Screen Comparisons: Contrast Ratio

I've been trying to understand the relative differences between the IPS displays used in the IPAD 2 and the Transformer, the Super PLS display of the Galaxy Tab 10.1 and the TFT used in the XOOM. I settled on contrast ratio as an objective means of comparison.
Article 1 XOOM: 750
Article 2 XOOM: 597!
iPad 2: 775
Galaxy Tab 10.1: 830
Transformer: 763
Article Quote: "Contrast ratio is also better on the Galaxy Tab 10.1: 830:1 vs 763:1 on the Eee Pad Transformer."
What surprises me the most out of all this, besides the XOOM discrepancies , is that the contrast of the Galaxy Tab 10.1 display is not as incredible as we were lead to believe. It compares favorably with IPS, but isn't really leaps and bounds better. In fact, it might have equivalent or slightly lower contrast than an IPS display, or conventional display but better viewing angles.
Interesting quote: "On the other hand IPS (and PLS) has significantly lower contrast ratios compared to the best VA based panels that Samsung and other manufacturers have used in high-end phones for years."
Side note is that the multiple contrast ratios for the XOOM screen might reflect the multiple screen sources/manufacturers that were used in different XOOMs.

The most important things to me on a tablet screen:
1. Color reproduction. Is it uniform and even? This leads me to
2. Viewing angles, top, bottom, left and right. Does the screen stay relatively sharp or does the image dissolve/wash out?
3. No back-light bleed. This is inexcusable regardless of the lectures people spout out about it being inherent to the technology. It's not when the product is designed correctly.
The panel in the GTab 10.1 is beautiful. It meets my criteria where the xoom failed on all of them and the iPad failed miserably on back-light bleed.
Contrast ratio to me is just a number. I have tolerances for all my electronics devices and to me, the panel on the Samsung is the clear winner in the tablet race. Let's hope the build quality follows suit. I'm already starting to get annoyed at how long a full charge takes.

The screen looks amazing! The only thing I noticed is that the screen calibration is a
little bit oversaturated. I'm planning on using mine as a photography/design portfolio and have noticed color shift when compared to my calibrated monitor.

I had Xooms (with both screen versions Auo and Sharp), an I pad and now a Galaxy Tab 10.1 and the screen on my tab is far and awy better than all of them.
The Xoom has 2 screen fkavors, Sharp and Auo optronics. the screen mfg by Sharp had much better color saturation and better contrast, but unfortunately for me, a ton of light bleed due to a defect in the panel.
Specs only tell part of the story.

When Samsung releases the kernel source, supercurio can start developing his Voodoo Sound and Screen tweaks for the SGT 10.1, which will make color reproduction much more realistic.

I'm new with android and this is awesome to hear. I also own the iPad 2 and Datacolor made an in app color calibrated picture viewer called SpyderGallery but an overall screen color calibration would be awesome!

I threw these numbers out there because, so far, almost all the info on PLS panels used in the Galaxy Tab 10.1 has been primarily subjective. Its totally new technology.
However, recently, Samsung has started to develop the PLS Panels for use in stand-alone computer monitors, and some reviewers are beginning to analyze and reveiw the technology. This is a really interesting article, and "sheds some light" (to make a bad pun) on the PLS panel technology used in the Galaxy Tab 10.1, how it works and some of its pros and cons:
http://www.xbitlabs.com/articles/monitors/display/samsung-sa850.html
Remember this is a stand alone PLS monitor, so one would expect its performance would exceed that of an integrated tablet screen, but they found a contrast ration of only 545:1. Thats pretty bad in my opinion. They try to theorize why this occurs:
"The low contrast ratio may be due to the poor uniformity of the backlight. The picture based on the results of my measurements shows a bright spot in the center of the screen, just where I measured the contrast ratio. That spot is not as bright as the bottom left corner, though.
Although the extent of the variation in brightness is exaggerated in the picture for illustrative purposes, the monitor is obviously far from ideal, especially with black. Talking about the exact numbers, the average nonuniformity of brightness for black is 8% whereas the maximum deflection from the base level is as high as 45%! For white, the average and maximum are 3.6% and 8.3%, respectively. It’s hard to say why the monitor is so good with white and so poor with black....."
So, disturbingly, they found the first dedicated PLS prototype monitor to have POOR contrast ratio!! Not what you would expect. They theorize that it might be due to poor backlighting, but it is worrisome.
To summarize what the reviewers found after examining this prototype PLS monitor:
Highs:
•Low response time, good color rendering, excellent viewing angles
•Full coverage of the sRGB color space
Lows
•Low contrast ratio
•Poor uniformity of backlight for black
If this review is accurate, these first panels seem to show that the PLS technology is good, but not great. Its an OK alternative to IPS but really not that stellar in its performance. Its biggest advantage seems to be that it is a cheap alternatative to IPS that has much better viewing angles.
Remember, one of the biggest selling points cited by Samsung was cost! Its cheaper to produce than IPS. That may be a larger motivation to Samsung than increased performance.
Of course, how this translates to the performance of our own toys is debateable, but its something to think about beyond the subjective impressions we have already heard.

That's definitely interesting. Perhaps the larger the panel, the greater the difficulty in achieving a uniform amount of back-light. I have definitely experienced this with clouding and flash-lighting on TV sets (and mainly the reason I switched to plasma - I'd rather roll the dice with image retention than sit and stare at uneven back-lighting during movies)
Have you read about the issues Samsung's having with the panel thickness on the GTab 8.9? There's not much other than a translated-from-Korean report, but it seems the company (and panel suppliers) use a very thin "G1F" touch panel for the 10.1, and may be forced to use a (40%!) thicker application (GFF) for the GTab 8.9 due to either shortages in supply or complications in the manufacturing process.

Thanks. Very interesting article. Especially considering that there has been a lot of talk about the quality control of the existing 10.1 panels. There have been threads about moisture under the screen, dust under the screen, lots of people with dead pixels. Haven't encountered nearly so many screen anomalies in other device forums. Wonder if that's the reason the GTAB 10.1 is so scarce in many places. Perhaps there are problems producing the 10.1 screens.
Oh and I went Plasma for all my TV's as well for the same reason, in addition to the faster response time. Even my video gaming TV is a Plasma. And I have never had a single problem with image retention.
Edit: Looks like another website has an article about the screen supply problem, only this time relating specifically to the GTAB 10.1. They speculate on a change in GTAB thickness if they can't make enough of the screens.
http://www.slashgear.com/samsung-galaxy-tab-10-1-to-be-thicker-than-ipad-2-due-to-supply-shortage-10158766/
Maybe soon there will be THREE versions of the GTAB 10.1: The 10.1, the 10.1v and the 10.1 series 2 extra thick!

I just found dust on my screen. Its definitely behind the glass panel.
Samsung Galaxy Tab 10.1

Slashgear is rife with editorial errors. that article misquotes the one I linked earlier. They even have published content that indicates it's the 8.9 and not the 10.1 affected but the different panel thickness:
http://www.slashgear.com/galaxy-tab...tter-screen-in-some-areas-at-launch-10158611/
Either way, I doubt the US will see the thicker screen - they continued shipping AMOLED phone displays here despite a worldwide shortage, causing many other markets to receive Super LCD screens instead.

Note 1 vs. Note 2 vs. S3 "SPPI" Comparison

So before I post this i'd just like to say this is my 1st post, and because of that I was not able to share links to the websites that I wanted to. So if you would like to visit the websites that I point to where I have only quotes with no links, just Google "oled-info note 2 display" and the first website to come up should be where I posted essentially the same thing and you can see the websites I am pointing to. Thanks!
Ok so all of the talk on different articles and forums about the Note 2's display about it not being a pentile, but also not being the SAMOLED+ with the typical RGB stripe got me thinking. Before the pentile discussion began to get heated all over the web, everyone was concerned about their phones' PPI. But obviously once the pentile displays came out and veered away from the typical RGB stripe (maybe there have been other display types b4 the pentile but that’s kind of irrelevant to the point I am going to make) there became a whole ‘nother thing to consider when it came to display clarity. IMHO this clarity comes down to the smallest part that makes up the picture, and that, for all intents and purposes, is the sub-pixel, not the pixel itself.
Now personally when the Note 2 was 1st announced I was pissed that Samsung decided to make the screen bigger and lower the pixel count because I currently have the S3 with Sprint and for me personally, the bigger the screen the better because I use my phone for TV and movies all the time. Now I understood that they wanted to have a 16:9 aspect ratio, but then why not just increase the horizontal, or both, resolution, not decrease the vertical! Especially since it was not a SAMOLED+, but just a regular SAMOLED which obviously meant another pentile right? But then I started reading into the screen and found out that even though it does not follow the typical RGB stripe, it does in fact have all 3 red, green & blue sub-pixels in each pixel instead of sharing pixels like the pentile does, which is shown very clearly in this picture:"".
So this got me curious because as I stated before, at least to my eyes, the sub-pixel count seems to have a greater affect on image quality than just the pixel count itself, which to me was proven when I got my Sprint Galaxy S2 and even though it had the same number of pixels with a .52" larger screen than my original Galaxy S, the screen clarity on my S2 was noticeably better which, if you dont consider the sub-pixel difference, should not be true. So I decided to do a comparison between what I am going to call the "SPPI" (Sub-Pixels Per Inch) of the original Note, the S3, and the Note 2 as I own a S3 and as much as I would love to have a larger screen, I really would not be happy with the huge loss of quality that would normally come when you stretch the same amount of pixels by .7" as the S2 has a 4.8" screen and the Note 2's display is 5.5", and what I found out really surprised me.
So here's the math of how I got to my conclusions. 1st of all according to the information from Samsung that can be found here: "" the sub-pixel count on the SAMOLED WVGA screen is 768,000 and for the SAMOLED+ WVGA screen it is 1,152,000. Now a WVGA screen is 800x480, which comes to 384,000 total pixels, the Note 1 is 1280x800 which = 1,024,000 and the S3 and Note 2 both are 1280x720 equaling 921,600. Now at this point I needed to figure out the number of sub-pixels on each phone by doing a simple algebraic comparison of the number of pixels to sub-pixels between the WVGA screen and each one of the other phones, which is done here:
Note 1: 384,000/768,000=1,024,000/x and x = 2,048,000 sub-pixels
Galaxy S3: 384,000/768,000=921,600/x and x = 1,843,200 sub-pixels
Note 2: 384,000/1,152,000=921,600/x and x= 2,764,800 sub-pixels
Now at his point I needed to take the aspect ratio of each phone, which is 16:10 for the 1st Note and 16:9 for the other 2 phones, and use the formula on this website to get the horizontal and vertical “sub-pixel resolution”: "". In doing this I came up with the following resolutions:
Note 1: 1,810 x 1,131
Galaxy S3: 1,810 x 1,018
Note 2: 2,217 x 1,247
I then put that information in with the screen sizes in this website: "" and came up with the following “SPPI” results:
Note 1: 402.7 “SPPI”
Galaxy S3: 432.6 “SPPI”
Note 2: 462.5 “SPPI”
So in a similar scenario as the Galaxy S vs. S2 screen clarity comparison, as long as my calculations are correct, theoretically not only should the Note 2 have a better clarity than the original one despite having a larger screen and lower resolution, it should also be clearer than the Galaxy S3! I have to say I was shocked at that and very much look forward to actually holding one in my hand to compare against my S3. I’d like to hear some opinions as to whether in general people agree or disagree with what I came up with here and for anyone that has held the S3 and Note 2 side by side if these calculations hold up in the real world.
Thanks!

**Quick edit: as someone on a different site pointed out to me, the screen size on the Note 2 is actually 5.55", not 5.5". So according to the members.ping.de dpi/ppi calculator that I used for this calculation, the "SPPI" for that device would actually be 458.3. Not that it really makes any difference, but if I'm gonna do all this work I might as well do it right

In the words of Mythbusters.... "myth, plausible" lol
Swyped from my finger to your face, on my Samsung Galaxy Note.

What you say it's completely true... What you call sub pixel its just a diode led... So adding more leds per pixel gives you better quality.. Indeed the pixels are Rgb and not pentile as someone will try to say here... Does not matters how are they arranged a red/green/blue pixel its an Rgb pixel... That said your math are to complicated and it's easier..
It's 1280x720 =921600 pixels note 2
For Rgb its 921600x3= 2764800 sub pixels or leds but distributed in 921600 leds of each color
It's 1280x800 = 1024000 pixels note 1
For pentile its 1024000x2=2048000 sub pixels or leds because it's 2 leds per pixel distributed in 2048000x¼ red + 2048000x¼ blue + 2048000x ½green
So clearly Rgb arrangement has way more leds than pentile arrangements and finally as easy as
2764800÷5.55=498162 leds per inch in the Rgb arrangement and
2048000÷5.3=386415 leds per inch in the pentile arrangement
So that's why note 2 screen its way better than note 1 screen

Because the S3 and Nexus are both pentile displays with a 1280x720 res, they both have 1,843,200 sub-pixels and if u put that into the same ppi calculator as I used b4, inputting the same horizontal and vertical resolutions and just changing the screen size to 4.65", it comes out to 446.6 "SPPI" which is still less than the note 2

c'est bien ça.

Will you honestly notice the difference? At a glance I doubt it very much. If you are in a dark room and staring at it for long periods I'd start thinking about the refresh rate than the pxl density what is the refresh on all of these anyway?

The original Galaxy S has a total of 768,000 sub-pixels and an aspect ratio of 5:3, making the number of horizontal & vertical sub-pixels 1,131x679 on a 4" screen which once again according to members.ping.de ppi/dpi calculator the "SPPI" would be 329.8. So the difference between that and the Note 2 should be pretty significant!

right, pentile is not limited to RGBG
BUT: as the pics from verve showed it looks like we get a real RGB matrix (not the regular stripe, but still RGB)!
for us this means that the note 2 will have 50% (2x1,5=3) more subpixels (actually lesser because of the lesser resolution, see calc afterwards), and due to this fact it's almost sure that the "disadvantage" (in terms of DPI) of having a slightly bigger screen will be overcompensated by this fact!
some maths:
note 1: 1.280x800x2 = 2.048.000 subpixels
note 2: 1280x720x3= 2.764.800 subpixels
in total this is an increase of exactly 35% in terms of subpixels!
additionally the manufacturing quality of OLED screens from samsung increased during the last year, so i guess that at least the screen will be a real improvement! and i tend to say that 2gb ram will also make a feel-able difference!
don't get me wrong, i'm also a little bit disappointed about the specs,
but over all they are worth upgrading, at least from my point of view!

My apologies, I would have given you credit for finding out the total number of sub-pixels for those 2 phones in my post if I had seen it. It would have eliminated the need for me to have to figure it out to get to my conclusion. But I was more looking to find how many sub-pixels per inch there were more so than just how many total because I feel like having that allows for a good mental idea of how the screen clarity will compare to peoples' current phones. For example I have the S3 right now so I wanted to do this comparison so I could have some idea of whether or not the clarity will be comparable to that phone since it has a .75" smaller screen with the same resolution. Come to find out that theoretically it should be better and. Thats more why I created this post.. Once again though I apologize for not giving you credit where deserved

Well before I give you the figure I have to say first that all the screens I have been comparing so far have been Super AMOLED screens. And organic LED screens are VERY different than regular IPS LCD screens. I actually owned a HTC ONE X for a little while because I didn't want to have another pentile display because I was worried that the S3 would look kind of grainy like the original Galaxy S. So I upgraded from the S2 to the One X and within 2 days I couldn't take it and returned it for an S3(which ended up looking amazing). But when I had the HTC I even missed the 800x480 display on my S2, and that's because even though the One X has a VERY clear screen as far as not having any pixelation, the LED screens on the Samsung, IMHO, blow away the LCDs on One X. The blacks are actually totally black, not just dark gray lol, the colors are sooo much brighter and saturated because the contrast ratio is technically infinite as compared to I believe 1400:1 on the One X. So compared to the S3 the colors just look washed out. Now there are some people out there who don't like the colors being so intense, but I believe that it just makes everything you watch on your phone just so much more enjoyable. And as I said not everyone agrees but if you never used an S3, go to the store and put your phone side by side and you will notice a TINY bit more pixelation (I mean your nose basically has to be touching the phone lol) but MUCH brighter colors and MUCH deeper blacks. And because of the difference of how the LED screens display as compared to the LCDs just the numbers really aren't going to tell the whole story. So I would STRONGLY recommend not letting the numbers deter you from at least checking the Note 2 out in person. (If you couldn't tell by now I'm a strong advocate of Samsung's LED screens lol, but for good reason) So after that long-winded speech the simple answer is the One X has a "SPPI" of 541.2 lol

I was only disappointed by the screen resolution But this thread changed my mind, might switch to note 2 from S2, I still think the screen is big but the S-Pen and it's features are too much attractive :silly:

My apologies, I would have given you credit for finding out the total number of sub-pixels for those 2 phones in my post if I had seen it. It would have eliminated the need for me to have to figure it out to get to my conclusion. But I was more looking to find how many sub-pixels per inch there were more so than just how many total because I feel like having that allows for a good mental idea of how the screen clarity will compare to peoples' current phones. For example I have the S3 right now so I wanted to do this comparison so I could have some idea of whether or not the clarity will be comparable to that phone since it has a .75" smaller screen with the same resolution. Come to find out that theoretically it should be better and. Thats more why I created this post.. Once again though I apologize for not giving you credit where deserved

Well before I give you the figure I have to say first that all the screens I have been comparing so far have been Super AMOLED screens. And organic LED screens are VERY different than regular IPS LCD screens. I actually owned a HTC ONE X for a little while because I didn't want to have another pentile display because I was worried that the S3 would look kind of grainy like the original Galaxy S. So I upgraded from the S2 to the One X and within 2 days I couldn't take it and returned it for an S3(which ended up looking amazing). But when I had the HTC I even missed the 800x480 display on my S2, and that's because even though the One X has a VERY clear screen as far as not having any pixelation, the LED screens on the Samsung, IMHO, blow away the LCDs on One X. The blacks are actually totally black, not just dark gray lol, the colors are sooo much brighter and saturated because the contrast ratio is technically infinite as compared to I believe 1400:1 on the One X. So compared to the S3 the colors just look washed out. Now there are some people out there who don't like the colors being so intense, but I believe that it just makes everything you watch on your phone just so much more enjoyable. And as I said not everyone agrees but if you never used an S3, go to the store and put your phone side by side and you will notice a TINY bit more pixelation (I mean your nose basically has to be touching the phone lol) but MUCH brighter colors and MUCH deeper blacks. And because of the difference of how the LED screens display as compared to the LCDs just the numbers really aren't going to tell the whole story. So I would STRONGLY recommend not letting the numbers deter you from at least checking the Note 2 out in person. (If you couldn't tell by now I'm a strong advocate of Samsung's LED screens lol, but for good reason) So after that long-winded speech the simple answer is the One X has a "SPPI" of 541.2 lol

another thing:
i'm with you that amoled is superb to lcd,
but few things about their disadvantages:
possible burn-ins
much more energy consumption as most people think
almost all displays have some tint (mostly yellowish or blueish), due to
big production (quality) differences between screens (had to cherry-pick my perfect one out of over ten (!) devices), there are a lot of threads about this. in short: screens from the middle of the 'wafer' are best, the more from the off-center your screen got cut out the more tint and uneveness you would have). this is due to the 'old' lithography process used, the new one (hope they used it with note 2 screens) with fine metal masks and perhaps lasers should improve this dramatically!
litte oversaturated, almost ever a not so good low grey level seperation (and often a bad gamma or mdnie factory calibration as well), search for gamma.png and or 'black crush' where low greys got cut-off
about contrast:
technically impossible to be oo!
black is NOT 100% black, as every (!) active oled screen emits a very small amount of light when active! also lots of threads regarding that, try it out: go into a totaly dark environment, display a black image and,VERY IMPORTANT, let your eyes accomodate for 1min! then look at the screen also with this method you will notice the uneveness and lithography projected dirt (dust) particles as with a microscope!
don't get me wrong, i love my amoled screen and i do not want to sound like a teacher!
but one has to be aware about this things as well...

Does the GS4 have the best phone screen?

I was playing around with the GS4 yesterday and the screen probably impressed me the most. I held it next to the GS3 and it was quite a bit better: sharper and brighter.
I haven't had the opportunity to look at the One yet, but I have to think the GS4 is a strong contender for the best phone screen. Of course it depends on your preference for AMOLED versus LCD; I probably prefer the former.
So to those who have been using the phone: how would you rate the screen? Do you consider it a big jump over the GS3 and how would you compare it to other phone screens, especially the One?

WAY better than GS3 but trades shots with the One.
I prefer a larger screen with true blacks so I prefer the GS4's screen. If you prefer a smaller screen and colour accuracy then the One's screen would be better.

"The best" is highly subjective. For instance, if you prefer outdoor visibility, it's still nowhere near iPhone or the One. That said, I prefer (properly calibrated) AMOLEDs for the contrast ratios and superior blacks despite all the drawbacks
Personal preference, really.

I have a One, and I have had a look at the S4 display. I have to say both displays look great.

You like Amoled then this is the best, if you like LCD real colors then One is the best. Personally prefer the One display.

It really depends on your preference. I have owned all the Galaxys, and some sony/HTC`s and i will say it is not.
There is no doubt the S4 screen is amazing, but only when it comes to colours. After using the S4 for a period of time, my eyes is starting to get tired. And thats because of the deep, saturated colours.
In the end it comes up to your personal preference. For me the Xperia Z/One is the best one. Nothing beats watching a movie on an LCD-panel.

While I love the screen on my GS4, I must humbly admit the SLCD3 screen in the HTC One is superior. While the blacks aren't completely black because it can't shut off pixels like AMOLED does, it's blacks are however very very impressive, color accuracy and sharpness are also more superior on the HTC One as well (the S4's Adobe RGB mode, aka (Professional photo) looks off a bit, especially on reds, so don't be fooled into thinking this option will make up for the inferior color accuracy). The only downside to the HTC One's screen, is it's only 4.7" which is a knock in my opinion as I prefer a larger screen.

So use Adobe RGB mode...

No it has really bad ghosting.

One of the best. I've recently switched to "movie mode" as various professional display reviewers have noted this mode as having the most accurate colors and I've been loving it. Feels more like an LCD which I used to prefer. I was also surprised at the amount of additional detail I'm seeing in movie mode that were not present in standard (for instance, the tapatalk app icon)
You will need a day to adjust from standard mode, but once you do I'm betting the standard will be hard to look at for you.
The resolution and PPI speak for themselves, obviously.

Note 2 screen looks great. No pen tile.
my gnote2 is bigger than your puny iPhone.

The s4 screen has a wow factor since the colors pop and the blacks are inky. The One's screen is great too much IMHO, the I prefer the S4 since it is bigger and more vibrant. The One's screen is like looking at the Iphone's screen but bigger since even on the Iphone you can't see pixels so it didn't wow me as much.

Guys i just compared my s3 to also mine s4 and must say the s3 display is sharper and I see more details on it. I just run few same clips on both. Can someone confirm it.

Samsung displays are horrible when it's outside in bright sunlight.

If you want vibrant colours they are the best. If you want realistic I'd say the One and iPhone 5 are the best. The movie mode is very good on the S4 but it's not as well calibrated as the iPhone 5s screen. Looking in the forum the S4 has ghosting/smearing and some weird pink tint issues. AMOLED screens also are poor in daylight and can get burn in.

Now that it has an option to show accurate colors. Displaymate rate it on par with iPhone 5 which is rated as the best LCD screen they tested in a mobile phone. For me SGS4 is the best out there simply because it offers best of both worlds. There is a mode to show vibrant colors which I personally like especially when watching movies. LCD will pale in comparison next to AMOLED which can show pitch black . It is still Pentile arrangement however I tried hard looking closely as I can and men I can't see any pixels or cross hatch pattern that I can detect on SGS3. I even think that it's icons are much sharper compared to iPhone 5. Now that the Pentile weakness has been totally eliminated by ridiculous 441 pixels per inch. Is there another phone out there that can beat this in terms of display?
From Displayemate which is world renowned for display diagnostics
Comparing the Galaxy S4 with the LCD Display on the iPhone 5:
The iPhone 5 is now more than half way through its product cycle, which is important to keep in mind for our comparison. However, high-end LCDs like the iPhone 5 are a very mature and refined display technology, so other than screen size, resolution, and the Pixels Per Inch not much is likely to change in the next generation, no matter what Apple decides to do. The iPhone 5 is significantly brighter than the Galaxy S4, particularly for screens with mostly peak white backgrounds. Its color calibration is a bit better, although the Galaxy S4 has a more accurate White. The Galaxy S4 has a much bigger screen, higher resolution, higher PPI, much darker blacks, and better screen uniformity than the iPhone 5. They each have their own particular strengths and weaknesses, but if you scan our color coordinated Comparison Table below, both displays are quite good and comparable overall – so it’s currently a tie – we’ll see how they both evolve and improve in the next generation…

With the current pentile matrix they are using and as high density as the 1080P display is, it doesn't affect the quality of the display.
Pentile really is no longer a useable arguement.

Seriously guys, calibration is not an issue. As long as you can get rid of that blue tint, I'm sure you'll get Perseus kernel with top calibration. I do on my Note II and it's absolutely perfect, if not better. Properly calibrated, AMOLEDs have an advantage when it comes to the contrast ratios.
Brightness still sucks though.

I've alway thought Samsung screens always looked too blueish and not so true to life. HTC always seems to get it right when it comes to screens. Just my opinion.

The ones slcd is superior to the sgs4... Yes the colors are more vibrant and black is real black... But there are too much downsides in my opinion:
- White just doenst look white - ok and full brightness, but not below that
- Loss of detail in dark areas
- Low brightness on automode (even on +5)
- Low brightness on maximum brightness (the ones slcd is superior in sunlight)
- Burn-In
- Pentile - still visible for me
- Smearing / ghosting
- power consumption on browsing
- red black (fixed?!)

Galaxy Tab Pro 12.2

Thinking about buying one.
Why?
1) Getting blind in my old age, well not blind but I need reading glasses
2) Bigger screen should be more natural with magazines
3) Has Android 4.4 (now I know I can root install custom ROMs etc... but I also had bad luck doing this with tablets)
Two questions,
It is only 2 inches bigger does that two inches make it much harder to travel with?
It runs the latest Android, does it run better?
It is expensive and I which when I bought my Note 10.1 (2014) .... what 3 months ago I knew this was coming.

has crossed my mind as well, I do a lot of reading/surfing/viewing and I don't really take it out much
saw one in a shop ...not exactly cheap not sure worth the extra coin being asked

Personal preference of course. Some things to consider.
It's huge and comparatively heavy.
The N10.1-14 is getting 4.4 and M-UX; it's already listed as a feature on Samsung's commerce sites. It won't get the Pro features but you can download the most meaningful, Hancom Office, in the app sub-forum here. There was some question about a modified version of the Tab/Note|Pro s/w because we have a menu button and those devices have replaced it with a task button. N12 owners have reported that long-pressing the task button provides the menu function we have which means it's one set of s/w with different button function mapping. Other than the remainder of missing Pro features the only two other unique features to the N12 are four multiview windows (vs. our two) and an expanded keyboard with FN, ALT, CTRL keys.
The N12 has an inferior display because the same pixel count that's on the N10.1-14 is stretched out over a larger area. The N12 has a gross PPI of 247 compared to 299 on the N10.1-14. Both use a RGBW PenTile display which means the net RGB pixel count is 227 and the N10.1-14's is at 274. The iPad Air is 264. A couple of reviewers have mentioned seeing a difference between the Tab|Pro 8.4/10.1 and N10.1-14's displays when compared to the N12.
It's got a bigger battery and will outlast the N10.1-14. But the Exynos N10.1-14's take forever to charge so increase that even more for the N12.
It's got USB 3.0 but it does nothing to improve charging time and increases data transfer rates on Windows (only) PCs that are USB 3.0 equipped.
So in the end, especially after the N10.1-14 gets its updates, there's not a lot of difference between the two h/w and s/w wise with the biggest exception being a fairly low (for a 1080P display) net RGB pixel count of 227 on the N12. For reference the N2's 720P display had a net PPI of 267.
Happy deciding.

It's really nice. I don't think the extra size makes it harder to travel with. It is noticeably larger, and you see it the most when holding it with one hand while tapping and navigating with the other. Because it is larger and heavier, there's a lopsided weight to it to where it feels like it's trying to twist out of your hand. Nothing overly dramatic, but you do notice it every time. Unlike the Note 10.1 where your hand covers a larger part of the device and so there is less / none of that feeling. Any type of case etc would most likely mitigate the issue. Other than that the screen is beautiful, sure it may be lower density but nothing I ever noticed after using the Note 12.2. You'll really appreciate the larger nature of text and graphics however, and that is priceless.

May I ask how did you get the net PPI figure?
Note 10.1 has an RGBW matrix made of ~4 Mpixels (2560x1600).
This equals to the same subpixel count as a ~2.7 Mpixel RGB panel (PenTile only have 2 subpixels per pixel compared to RGB's full 3 subpixels)
Which means that our Note's effective resolution is 1306x2090.
So the hypotenuse of the panel (via the pythahorean theorem) equals to the equivalent of 2464 RGB pixels
Which finally means that we have an effective 244 PPI (2464.5/10.1)
Which is lower than Ipad's but higher than other 10.1 inch android's. iPad's screen also consumes far less battery has (arguably) better colours and most importantly does not suffer from the grayish blacks we suffer. In short if you want the best "large" panel in the market you have to go to Apple, for everything else our note is the best deal.

Seriously?
The effective PPI of the N10.1-14's display is 299 PPI. It's achieved somewhat by slight of hand by using combinations of sub-pixels to create the illusion of more. That's the very definition of PenTile whose impact varies greatly based on implementation. My simple formula is essentially just factoring in the loss of 25% of the RGB sub-pixels to the added white ones and distributing the lost pixels across each of red, green, and blue. .
From WiKi...
PenTile RGBW technology, used in LCD, adds an extra subpixel to the traditional red, green and blue subpixels that is a clear area without color filtering material and with the only purpose of letting backlight come through, hence W for white. This makes it possible to produce a brighter image compared to an RGB-matrix while using the same amount of power, or produce an equally bright image while using less power.
The PenTile RGBW layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the human eyes' red-sensing and green-sensing cone cells, while using the combined effect of all the color subpixels to present lower-resolution chroma (color) information to all three cone cell types. Combined, this optimizes the match of display technology to the biological mechanisms of human vision.[13] The layout uses one third fewer subpixels for the same resolution as the RGB stripe (RGB-RGB) layout, in spite of having four color primaries instead of the conventional three, using subpixel rendering combined with metamer rendering. Metamer rendering optimizes the energy distribution between the white subpixel and the combined red, green, and blue subpixels: W <> RGB, to improve image sharpness.
The display driver chip has an RGB to RGBW color vector space converter and gamut mapping algorithm, followed by metamer and subpixel rendering algorithms. In order to maintain saturated color quality, to avoid simultaneous contrast error between saturated colors and peak white brightness, while simultaneously reducing backlight power requirements, the display backlight brightness is under control of the PenTile driver engine. When the image is mostly desaturated colors, those near white or grey, the backlight brightness is significantly reduced, often to less than 50% peak, while the LCD levels are increased to compensate. When the image has very bright saturated colors, the backlight brightness is maintained at higher levels. The PenTile RGBW also has an optional high brightness mode that doubles the brightness of the desaturated color image areas, such as black&white text, for improved outdoor view-ability.​RGBW is funky in that when displaying certain fully saturated colors (yellow and green have been given as examples) on a white background there's some granularity issues on hard graphics edges.
Also from WiKi...
However, for the same resolution and size the PenTile screen can appear grainy, pixelated, speckled, with blurred text on some saturated colors and backgrounds when compared to RGB stripe color. This effect is understood to be caused by the restriction of the number of subpixels that may participate in the image reconstruction when the color is fully saturated. In the RGBW case, this is caused as the W subpixel will not be available in order to maintain the saturated color. For all other cases, text and especially full color images are fully reconstructed.​The impact of PenTile depends on PPI and even more so on visual acuity - the point at which the viewer's vision intersects one arcminute. For people with 20/20 vision holding a device the typical 10-12" away you can't see that the N10.1-14's display is PenTile; at least from a clarity perspective. Some people here with 20/10 vision have seen the RGBW saturation issue. I, with 20/20 vision, haven't.

I honestly don't get your point, a rectangle is made of two triangles whose hypotenuse is the diagonal of said rectangle, which is why one can use the pythagorean theorem to find the diagonal's pixel count.
As for the rest I calculated what's the effective PPI of our device is in RGB terms, again I don't see where I'm wrong. I called it effective because most screens use an RGB panel. A 1306x2090 panel produces exactly the same sub-pixel count as our note. Now due to subpixels' placing one may see a different picture altogether, but holding our note side by side with an Ipad it is more pixilated, which shows to me that the 299 number is literally meaningless since we are talking about a different screen tech...

Yeah I would have done it the same way Stevethegreat did. But I'm not familiar with how they create the illusion of more subpixels.

You guys do know that a rgbw pentile display doesnt render images in full pixels like a rgb panel right? Thus making a comparison of the two technologies a pissing contest at best. A rgbw panel renders images at the subpixel level using any arrangement of the subpixels to achieve the desired image (in a way more natural and easier on the human eye) whereas a rgb renders images using the entire pixel (all 3 subpixels as a solid unit) it takes a rgbw display 1/3 less subpixels to display the same resolution image with no loss of image quality. Yes if you jam your face into the thing you will notice the pixels slightly sooner than a rgb. All that means is you look less like an idiot while pixel peeping with the rgbw. On text you will never notice a difference. One of the biggest electronics companies of all time keeps using pentile panels and keeps getting great screen reviews in its products. Shut the stupid pentile assault down. I cant even recall a reviewer knocking any of these screens. At normal viewing distance they are marvelous. If you dont use it at a normal distance congratulations your the minority that uses his tablet pressed to his face. Oh the and the "slight" loss of sharpness on the display in comparison to the note 2014 is made up for by a larger screen used FARTHER AWAY meaning that with normal vision no discernable difference. And lastly in what universe have you compared the note 10.1 to the ipad air and found the note more pixelated? Even factoring the lost pixel count (BarryH_GEG is right) the note is superior to the ipad. The rgbw panel doesnt need the extra pixels because it looks just as good without them. And if it looks just as good whats your problem?
Op the 12.2 offers alot more screen real estate. It is a bit heavier but unless you have lost tge ability to wipe yourself you will easily be able to carry it around. My 90 year old grandmother still carries an ipad 3 (same weight). The screen is very efficient and this tablet is consistently beating the ipad air in battery tests. It will take awhile to charge if you allow it to drain all the way. Which you shouldn't do. Charge it when not in use and you will be fine. 4.4 is smoother and the pro features are nice. I would also point out that the charging port is on the side making use while charging much easier. If you are intrigued by its size try it out. Worst case you return it.
Sorry guys for ranting but I keep seeing the same false information over and over again. Your splitting hairs between ridiculously good and slightly more ridiculously good and smaller.......just like that stupid 4:3 is better for reading thing. (IT IS NOT IN ANY WAY BETTER)

Samsung obviously believes that pentile is the way of the future. they seem to be selling the idea very well.

@ Duly.noted: OK I get you dislike of ipad and it is not without merit but I was comparing the sub pixel count of our device with that of ipad's and unlike what BarryH_GEG said my calculations are not wrong, you said it yourself we have 1/3rd less subpixels. Now I often keep my tablet at a distance of 8-10 inches close to my eyes. Granted I keep it closer than most people, and also -granted- text looks better but everything else *doesn't* and *that's* my point, technically we have a worse screen but to most people it is just fine. It is not splitting hairs though, I would much prefer ipad's panel but then I would lose android's flexibility and the spen
As an experiment put a red text in a yellow background and *tell* me that it looks the same to you (same clarity) as in an ipad, because it sure as hell doesn't to me.
Anyway, this thread is about Note 12.2, so imagine it as a thought experiment in an even larger more spread out fashion. Again to many people this is splitting hairs but I think it is more important to let more people learn of the impact of pentile technology than simply call the panel a 2560 x1600 panel and be done with it. I'm surely not as happy to learn about it *after* I bought the tablet, but you're right it may not be that big of a deal, the biggest deal by far (for me) was/is the "milky" blacks and the atrocious gamma raise when looked at from different angles, both not expected from a panel of this calibre. I sure hope that note 12.2 have/had this issue fixed, because especially in such a large panel it would make quite an impact to its picture quality. Much more than the pentile arrangement would (even in principle) be able to make.

Sorry guys for ranting but I keep seeing the same false information over and over again. Your splitting hairs between ridiculously good and slightly more ridiculously good and smaller.......just like that stupid 4:3 is better for reading thing. (IT IS NOT IN ANY WAY BETTER)

Yes you are ranting, fine if you want to do that, but your rant has almost nothing to do with the post you quoted. It it not about false information, whether the screen was good enough, nor 4:3 ratio. It is about methodology for calculating PPI. That may be interesting for someone comparing a Tab Pro 12.2, Note 10.1 2014, or an ipad.

I am debating which one to get- the note 10.1 2014 or the tab pro 12.2. Does the screen size make it a must have?

Here's my input. I had the Note 12.2 for about a week. I returned it without hesitation for the Note 10.1 (14). Why?
1. It's heavier. I came from an original Tab 10.1 and one would think that 4 ounces more isn't a big deal. That's what I kept telling myself. Yet it is. My hand got tired holding it very quickly where it never got tired holding the 10.1.
2. It's larger. Well, you say, that's the point isn't it? Yeah, but there's an odd thing about it being larger, it's harder to hold it. If you remember your physics class then you'll understand that the center of gravity for the 12.2 moves further from the hand than the 10.1. Throw in 4 ounces more weight and the torque applied to the hand makes it uncomfortable to hold in one hand.
3. The screen is just bigger, not better. The apps don't use the real estate better. They're just larger. It's like putting larger buttons on a pushbutton phone. You don't get more buttons, you just get larger ones. It's the same with your TV. A 50" screen has the exact same number of pixels and resolution as a 40" screen, just larger. Now, for us folks getting older one would think that this would be a good thing. It wasn't. It just didn't feel right.
4. Magazine UX. It was fun. For about 30 minutes. Because it was so limited I found it to be boring after a short period of time. I installed Apex.
5. When I combined it with a Zagg hard keyboard case it did a fine job as a desktop device. The keyboard was full sized and easy to use. Felt great. But, then I found myself pulling out my 15.6" laptop for those times instead. After all, if 12.2 is good on the desktop 15.6 is better.
6. One thing that I really liked on the larger screen was the ability to have up to 4 apps running at once. Mult-apps feels cramped on the 10.1" screen and it felt much better on the 12.2" screen.
My comments here are very personal and may only apply to me. They're intended to be a "heads up." Here's what I'd recommend to anyone thinking about getting a 12.2" tablet. Buy it at Best Buy or any other brick and mortar store that permits easy returns. Try it out, you'll know in a few days if it's for you. If you don't like it just return it. No harm done. (Don't do this at Fry's, they charge a 15% restocking fee.)

Side note on PPI:
PPI doesn't matter. Look at the screen. Run the apps you normally use. Do you like what you see? Yes? That's all that matters. Period.

So I'm hoping to try all this out and see if it bothers me. I've never had a tablet before, but I've used the tablets of others.
I am hoping that I can root the thing and change a couple of the things you were mentioning. For example, I'm on a G2 right now, having the same issues with a bigger screen/apps are just bigger. I changed my LCD density (effectively the screen resolution) and now have a much better use of the real estate on the screen.
Another big test would be if the S-Pen works well on the Tab Pro (yes that's right Tab Pro). You would instantly save $100 minus the difference for buying a stylus. I don't care for the S-Pen software, just the handwriting capability.
I am also nervous about all the bloatware/UX that comes with it... I'm a guy that buys a phone and has it rooted/ROM'd before I go to bed. We'll see how long I last....

There are many of us who like to read , for many hours. Be it literature, articles, long emails. While a screen may look beautiful at first glance after long hours it can and will become tiresome if the PPI is below some threshold. As a reader PPI is the first I look for when buying a new tablet. Fortunately note's pentile handles text beautifully so I suspect it would not be a problem for note 12.2 either

It won't work. The tab pro doesn't have an active digitizer. It wouldn't even work as a capacitive stylus. You'd just get nothing.

Well that blows. I mean.. you can draw with your finger... so why wouldn't any stylus work?

A capacitive stylus is made with a material that effects the electrical current of the touchscreen causing it to register as a touch in the same way a finger does. Pieces of metal will register as well. The spen is a active stylus. The tip is a nonconductive rubber or plastic tip and it affects the touchscreen using a magnetic field detected by the digitizer layer. This allows much greater accuracy and by increasing the magnetic force with a button sensitive to pressure allows pressure sensing. However, it would not function on any device that did not have either a resistive touchscreen or digitizer layer.

People still on Note Pro 12.2, will you be jumping ship to the Galaxy Tab S7 Plus?

Link:
https://www.sammobile.com/news/exclusive-samsung-galaxy-tab-s7-plus-specs/
I personally am thinking about it but the bigger screen uses AMOLED, which is a turn-off for me with regards to longevity but the other model feels like a downgrade in terms of screen size.
How about you guys?

For the amount of money the ask, no.
Maybe with future discounts.

I've been reluctant to give up on my unlocked Verizon Samsung Galaxy Note Pro 12.2 with the original keyboard. As long as I can get a decent price on the Bay for the 12.2, I'm gonna be picking up the S7+.

Yeah, it's literally double the amount that I paid for for the Note Pro. I've seen it IRL and it's smaller but I'm not that impressed and it uses AMOLED, which is a big turn off. The S7 would have been nice but the screen downgrade stings.

For that price, why not go for any windows machine with an aspect ratio that doesn't letterbox everything?Assuming you use it for media consumption anyway.
Wish it was easier to find a reasonably priced replacement for this old boy though.

I was going to the S7+ 5G , because the P905 is now so slow, that I can't use them anymore to play pinball. Interesting fact is, that it was possible in history....Also if I fall back to the stock rom with minimal apps...The games freeze more or less.
The S7 is another Liga...but if I think of the price 6years ago for the P905...it was nearly the same

Not until the price comes way down, or I get a second hand one. Plus I want to see if anyone roots it and begins providing OS updates, given manufacturers all have a history of quickly cutting us adrift regarding updates.
I cut out a sheet of paper the same size as the S7+ screen yesterday and laid it over my Note Pro. The S7+ display is only a few mm difference.
I have waited for the S7+ but its 16:10 aspect ratio irritates me. I don't know why Android manufacturers are fixated on it. Samsung has cut out a large number of potential purchasers by not adopting something closer to the 4:3 aspect ratio of ipads. While I realize it's because most movies fit that better, ipad users watch plenty of video too and it doesn't seem to be hindering ipad sales any.
One examples of buyers they've cut out are the many people who deal with anything related to paper. Turn a tablet vertical to read documents and the 4:3 aspect ratio is a much closer fit. Whereas the 16:10 aspect ratio is narrower with bars of blank space top and bottom. This narrower width compared to its height also makes text smaller.
To match the width (and therefore text size) as a sheet of A4 paper on a 16:10 screen, you must go all the way up to 17". Whereas a 15" 4:3 screen is perfect.
Another group of buyers driven away (not all of course, but many) are musicians. Those musicians who use tablets mostly go with ipads, which are not ideal either because ipad pro screens are still smaller than paper. But at least they're much closer to paper aspect ratio without the 'side scrunch' and black bars of 16:10.
There are e-ink devices made specifically for musicians. But they're far too expensive given the typically ONLY good things about them is their e-ink screens, and due to that, long battery life. But their lack of features, limited hardware like processors, storage, and lack of provision for peripherals are pitiful to ridiculous given their price.
