Nexus One Pentile solution?

I think most of us with Nexus One's have discovered or read about the display's PenTile pixel setup. I am frustrated, because I look at a Droid, and the resolution seems so much better. But maybe, hopefully something can be done about this.
My main question is: How would one go about tweaking/changing the Pentile display driver hardware?
Supposedly, you can eliminate color fringing by tweaking certain register values in the display drivers and reducing the amplitude of modulation. It sounds like you basically need to stop the locally adaptive filter detector.
This article describes the whole issue:
ww.metalev.org/2010/03/more-on-resolution-of-nexus-one-display.html
Have any of the developers out there discovered tweaks and/or fixes for this dilemma? Is anyone like cyanogen working on improving the nexus' resolution?

Sorry I have no idea how to address the issue, but as with the rest of the bugs my hope is that if we continue complaining/discussing them they should eventually register on googles radar as something important to their consumers and be addressed. I feel sure Google keeps tabs on sites like this and particularly this one, its in their interest to after all.

Are you actually looking at a physical Droid and saying this, or just looking at the article pictures?

Uh, no. Don't lie. You can't tell the difference with the naked eye.

Uh, yeah, you can. Within seconds of turning my screen on the first time I knew something was up. It didn't look as good as it should for an 800x480 screen.
The actual resolution is:
Green sub pixels - 800x480
Red sub pixels - 400x240
Blue sub pixels - 400x240
They're able to get away with this because the human eye is more sensitive to green, so the lower res red and blue don't detract too much from the image, but try displaying anything that is pure red or blue or really anything without green, and suddenly the actual resolution is worse than even something with a crappy 480x320 display.
I'm disappointed.

Seriously...this is a non-issue. The moto may have better "edge" detail for texts but N1's screen appears to have better color range than the moto. Unless you're looking at it in macro level (nose to screen), Nexus One more-than-satisfies the regular on-looker. Trust me, it's no slouch. The overall package of the N1 more than makes up for the less-than-perfect screen.

i read all about this PenTile display issue, and honestly when i look at my nexus screen, it simply looks fantastic. so i dont buy it, or just dont care either way as long as it looks good. even the XDA app which has black background with small white text, the letters look super sharp to me. i dont see any fringing or anything.

Correction. There are one half as many Red and Blue subpixels, but you are indicating one quarter. 800x480 = 384,000 and 400x240 = 96,000, but there are really 192,000 Red and Blue subpixels.
The confusing thing about the layout is that they are checker-boarded so you can say "each of the 800 rows have alternating R&B" and you can say "each of the 480 columns have alternating R&B", but you can't say "every other row has alternating R&B" or "every other column has alternating R&B" which is what your numbers would boil down to.
The actual resolutions are:
Green - 800x480
Red - 800x240 or 400x480 depending on how you count it
Blue - 800x240 or 400x480 depending on how you count it

comparing my n1 to my buddies droid using color flashlight app from market, we compared colors on eachothers screens, the droid does not have as deep/dark of a black color as the n1, but does have a brighter white.

At first glance, I didn't notice a requisite 't' in the title of this article, and thought this was an entirely different discussion...
Seriously though, I have no issue with the screen, it's pixel count or clarity, and I haven't even noticed the 'color-banding' that the tech blogs all showed was 'sooo terrible' on this phone... Perhaps it's just me...
I think that if this is an item of concern for someone, and I believe that to be true of the original poster, then maybe this was not the best phone choice... maybe... There is always going to be something better than what you have at that given moment, it's just how things are. And the fact that this phone came out after the Droid means nothing to me... I wanted the Nexus One, and I got one, period.
Hey maybe since Cyangen is so fond of blue, maybe there will be a display 'little blue pill' to fix our phone's 'pentile dysfunction' but if there isn't (or it's not possible) I have zero regrets about my decision to buy a Nexus One...

Actually I think it is this checker-boarding, even more than the lower resolution itself, which is responsible for most of the issues where you can see the lower resolution. The text antialiasing, for example, has a red stippled noise along the edges that looks a lot like they didn't take the alternation of the red pixels into account when choosing which sub-pixels to turn on.
If the edges were "cleaner" then I don't think the resolution would be as noticeable. (Just IMO)
I think some software tweaks will make the situation much better, but it will always be a hassle for the software to deal with compared to a cleaner "3 subpixels in every pixel" arrangement that LCDs have... :-(

For what its worth, as far as the white vs black comment, I believe that is unrelated as far as the problem the OP describes. It could be true though.
OLED's like the N1 not only have the deepest blacks, but also use way less power displaying black. That is why the new WP7 is so centered on black, because it's designed for OLED screens and battery life. Maybe thats why Android features alot of black too.
The Droid is not just a different resoultion / color depth, its also a TFT LCD, which is different all around. OLED's are new. Its just first generation tech. Software could help alot, like with the Droid multitouch.

I'm pretty sure the "lower resolution" is not an issue at all, but as u say it's the PenTile sub-pixel layout that is a problem for many. I think that one has to have good eye sight to be able to notice it since there obviously are many who can't.
People who say it's a non-issue don't know what they are talking about. for many (including myself) the "fuzzy" text is very disturbing. I don't have any problems reading text on an lcd screen with standard RGB sub-pixel layout and with lower resolution but i do have problems with reading text on the Desire (same screen as the Nexus One) and not only very small text but normal size text as well.
Let's end the discussion about this being a real issue or not and focus on finding out if there may be a solution to the problem.
Does anyone know if it's at all possible to create some kind of software patch to tweak the registers and if so, how?

this has nothing to do with colour banding / checker board or colour issues of any kind, they were all false and related to the 16bit gallery which is software..
the problem is the sub pixel layout which causes edges to extend:

and this is what causes the blurry looking text
in one of the blogs/sites i read that the creators of this screen, or similar versions of it, had the ability to turn this feature off and light each sub pixel individually (green sub pixel as 2 separate sub pixels) or something along those lines but it wasn't clear if this was available in the nexus screen.
i will try to find the link

Ummmm...
When I said "checkerboarding" I was specifically referring to the way that the Red and Blue sub-pixels are laid out on the graphic that you posted. If you ignore the green sub-pixels they look like a red/blue checker board, no? That layout does complicate the task of using sub-pixel components to antialias text (the standard algorithms for which assume that all pixels have the same 3 sub-pixels laid out in the same order).
My comment had nothing to do with the false comments made by the "engineers" at DisplayMate.

This.
Anyone who claims otherwise, is a liar. The human eye can not differentiate pixels that small.

Looks great to me and looks great to everyone that looks at the phone and a lot of people do because they are attracted to the screen which, lol, looks great. Honestly I am not trying to make light of what is a problem for some but I cant help but wonder how many people would have this issue if they hadnt read about it. My guess would be very few.

Then I guess I don't have human eyes because I can see a blurry effect.
I've been well documented to love my n1 but the screen issue is a real issue. This comes down do how your mind puts together a picture. when looking at the n1 my mind usually creates a blurred spot on one part of the screen and its always there until I focus on it. this tells me it is indeed the screen causing this.
This is kinda of similar to how 1080i tv work. Th screen itself is only producing part of the picture but your mind does the rest. for the oled on the n1 this did not work out.

Reading Text on Super AMOLED

I remember a while back there was an article on Ars Technica (can't link yet, but google "ars Secrets of the Nexus One's screen" and you'll find it) about the Nexus One's AMOLED screen. They talked about how the AMOLED screen technology/layout resulted in text that wasn't as sharp as on the Motorola Droid. I'm curious if this is still a concern with Super AMOLED technology, as with the Epic 4G?
I'm looking to upgrade from my Palm Pre in the next few weeks (hoping the Epic 4G is out by then), but I'm hoping to do some background research before that. I use my phone quite a bit for web browsing now, and would probably increase that usage on a phone with a bigger screen and better browser. I'm also looking forward to being able to use Kindle's software for Android. Bottom line is that I know I'll be reading a LOT of text on my phone. Super AMOLED is supposed to be incredible for pictures and video, but if it's lackluster on text, it's not as useful to me.
If any of you have any thoughts or experiences regarding this issue (if it still is one on Super AMOLED), I'd love to hear it. Thanks!

Yes, it's still an issue.

SAMOLED Pentil subpixel layout makes text look jaggad compared to LCD. The reason for this is that the true addressable resolution of SAMOLED displays is not 480x480 but 393x653. This is the one drawback of this display. See my other posts where i compared the LCD of the EVO vs the Galaxy S. Additional problems are screen burn in and poor power consumption for mobile devices. Text on white backround (web browsing, document viewing) consumes 330% more power than LCD. The color saturation, contrast, black level, and viewing angles are stunning though.

I checked out your "Galaxy S (Epic, Captivate etc) VS EVO Comparison and thoughts" thread and it was an excellent overview. I'm leaning towards the Evo for the larger screen and better text readability. I'm out of town right now, but when I get back home next week I might try to track down an Evo somewhere. If the Epic comes out within the 30 day trial period, I'll check it out then.
The main things tempting me with the Epic are the nicer CPU & GPU, but I'm pretty sure I'll be happy regardless after being on my sluggish Pre for a year. If only Palm had been bought by someone who could have brought some of WebOS's features to Android (I think I'll miss having cards and gestures). Either way, both look like excellent phones and I'm anxious to get started with Android.
Thanks for the feedback!

If that's the reason that it comes out like that, will the text be fixed when Android Gingerbread comes out? I've heard that gingerbread changes the resolution, but I don't know if that's true.

Visit a T-Mobile or AT&T store and look at the Captivate and/or the Vibrant..the Epic will have the same screen..once you see it you can judge for yourself...the text may not be as sharp but it may be acceptable by your use...so its worth checking..

I have a evo and do pretty much nothing but text reading (ebooks and the web). Text is very easy to read and I have not noticed any eye strain yet.
That sucks about super amoled not doing text well.

I tried doing that at a Best Buy yesterday but someone had stolen their demo unit(s). Apparently it's one of the more ghetto Best Buys in Boston. Who knew. I'll be checking it out when I get back home for sure though.

Hmmmm.... I went to the AT&T store last week, to check out the captivate and I didn't notice any problem in reading the text personally. I haven't made the switch to a smartphone yet so maybe my eyes are too inexperienced to notice something like that, but I'm pretty sure I'll be happy with my future Epic 4G

I have the captivate and yes, text on it is not as crisp as on the droid or droid x. But is it an issue, no. On really light colored backgrounds like white or light grey, if you look hard for it, you can see some fuzziness. But on colorful backgrounds you really cant see it. I can tell you, its a beautiful screen. Overall it looks better than the droid x, which has been described as dull or drab. The colors on the S-AMOLED really pop, and the fact that its an OLED means that black backgrounds are really true black (complete absence of light).
In my opinion its the second best display available, second only to the iphone4 display.

The only way the retina display is better is if you're reading text from under 10" away from your face, but then again who the heck reads with a phone up in their face? I read alot of e-books and other sites and I can tell you reading a page from a normal distance there is little to no difference.
As far as video playback and pictures the Samsung blows the retina display out of the water and by leaps and bounds is the #1 screen in the phone market hands down.

i have to agree that retina display looks better in my opinion. I have pretty good eyesight so that may be why. However, it doesn't make a difference in eyestrain or readability.
I own a captivate and read ebooks on a white background regularly. Its honestly not an issue.

I'm more worried about screen-burn in, which is a very big problem for S-Amoled//Amoled screens.
With less than a year's use of my Nexus One, there is a slight amount of screen burn in, which isn't really avoidable.

Screen burn ins were only a real problem with the early model amoled screens, much like plasma HDTV the screen tech has evolved and it doesn't hurt that the Super Amoled screens are developed by Samsung which are global HDTV innovators.
Besides for screen burn in to become permanent the screen would have to be on for hours on a static image, on a HDTV I can see that happening if you fall asleep maybe but who on earth turns off their phone's screen timeout and let's the screen stay on all day chugging battery life? That just won't happen.
I'm FAR more worried about the phone's future in regard of updates than I am of screen burn in on a mobile device. Not to mention you have a warranty which 100% covers such a thing as screen burn in and if you do happen to burn in a screen it usually happens sooner rather than later.

I wouldn't be worried about that if I were you. The Galaxy S series is on all four major US carriers and will undoubtedly get a pretty large hacker following, so even if Samsung does stop updating the Galaxy S phones, there will always be cyanogenmod or many other custom ROMS. And if you're posting here, rooting your phone and installing a custom ROM shouldn't be a huge deal.

It is not possible to have permanent screen burn in..as for temporary one...even LCDs state not to keep the same image on for too long to avoid temp burn-ins...
As for updates...we are not sure how much of a bone Samsung will give, but at the moment, event the Sprint Moment has gotten a Foyo 2.2 by the community.

Is that 330% more power figure accurate for the GS screens, I was under the impression that they are different than all previous devices? I read a lot of text in my personal usage. I wonder if an app could be developed to make all white pixels black and black white? Although white text isn't ideal if it amounted to 350% power savings my eyes/brain could adapt eventually?

Well that is for the regular AMOLED screen...the Super AMOLED screen would most likely be around like 260% for that..but you gotta realize that your screen will never be FULLY pure white like that...the next revision of Super AMOLED(for 2011 plans to go RGBW to fix that).
Either way you'd never have so much white on the screen for it to waist that much energy...

About our displays.

Im pretty annoyed of all the people nit-picking about our displays, and how its grainy, etc. (The whole pen-tile thing). I was searching up on it and it is actually an advantage! it gives us better battery life, images are sharper than normal, and are brighter than normal while not using more battery, so you dont have to dim it to save battery (which i hated with normal displays).
anyone who is going to complain about it read this.

haha i know right! that has nothing to do with the display though, that is the accelerometer. and i love the display on this thing, i can actually see it in the daylight!! that has been a HUGE issue for me with HTC phones (almost every phone i have owned has been HTC). i can see it perfect walking down the street with the sun bright as sh!t. also the views on it, i can see everything still good when tilting the phone.

OP you haven't owned an iphone4 or SGS have you? Our display may be good for battery life but viewing angles, color reproduction and quality is garbage.
Not to mention the horrible gradients.

I have owned the Captivate, Inspire, and Atrix. I passed my Captivate on to the wife, and now when I pick it up, I think the display looks horrible, and think the Atrix is crisper, and brighter than the others.

The captivate had a much better display in my opinion.
I love my atrix though and the display is not "garbage" either.

The widgets looks so small on the Atrix qHD 960x540 screen.
Is there a way or app to switch the display to 800x480??

Did you even read the article you posted?
You get a higher resolution and better battery life and better whites, compared to LCD displays, at the cost of blurrier text, grainier images, and poor yellow and green reproduction.
And it may give better battery life compared to normal LCDs that don't use pentile since it has fewer sub-pixels to drive, but it doesn't give the same battery savings that are possible from OLED displays as those completely shut off any black pixels for both battery saving and for true blacks. OLEDs also have better whites compared to LCDs due to the nature of the technology.

Question: do our displays use less power to display white or black?

Yes on white, since only 1 sub-pixel needs to be used vs 3, and no on black.

Dude, whites on amoled are blue. It is true that amoled is not lit up when displaying blacks. However, it is the only advantage. In my experience every other color, especially whites can drain the hell out of amoleds. Oh and amoleds are prone to a permanent burn in.

Why such a debate? A screen is a screen, it shows images, and does what its gotta do.
If you don't like it, then you shouldn't have brought it in the first place.

Because TFT screens are as "pretty" as Amoleds, but they don't kill the battery like Amoleds either...

And it may give better battery life compared to normal LCDs that don't use pentile since it has fewer sub-pixels to drive, but it doesn't give the same battery savings that are possible from OLED displays as those completely shut off any black pixels for both battery saving and for true blacks. OLEDs also have better whites compared to LCDs due to the nature of the technology.

I don't even need to read the article to know how these screens act. From my personal experience, TFT screens give waaay better battery life than Amoled or even SLCD.
I've owned 4 different TFT phones. 2 Amoleds, 2 Super Amoleds, and 1 SLCD.
Take a non-TFT phone on a dominant white background website like Engaget for a while, and see how fast it drains on white backgrounds. Even with Google, I had to switch up to something as simple as Blackle instead.
No double Amoleds screens are "Eye-Candy", but they are like Gremlins where you have to keep them away from the light.
TFTs may look plainer and grainy, but you don't have change your browsing habits because of them either to save battery...

Im pretty annoyed of all the people nit-picking about our displays, and how its grainy, etc. (The whole pen-tile thing). I was searching up on it and it is actually an advantage! it gives us better battery life, images are sharper than normal, and are brighter than normal while not using more battery, so you dont have to dim it to save battery (which i hated with normal displays).
anyone who is going to complain about it read this.

I would not call it nit-picking, people are stating facts ... In your link above you have decided to take the article as a positive article, but some of the people would take it as a negative because they can resolve the pixels (good vision maybe) and can not put up with any artifacts or imperfections ...
My story is that i bought the atrix at its full price but i could not put up with the screen (everything else was ok like battery, gps ... another annoyance was the inability to type in macedonian language ... and yes i've checked the market for keyboards and stuff, no video calls because of the unknown status with gingerbread) so i have decided to replace it with Inspire which had better screen (at least to me) but terrible gps, battery life and the same problem with languages ... At the end i've purchased iPhone 4 and all of the features that i wanted to have are available ...
My criteria:
1. Good screen (accurate) /i do not care how many cores the phone has, if the screen is not good then the phone is not good too/
2. Language (keyboard) / Video call (phone to PC with skype or google talk)
This is how i see the things ... Different people have different priorities when they want to purchase phones, electronics ...
When so many people say that the atrix screen is grainy ... probably it is ... some can put up with it, some can not ...
Another high level article describing the positives and negatives of a PenTile screen from an expert in that area:

Take care

The Best Tablet Display

I just found this article written by someone who knows his stuff.
http://gizmodo.com/5824807/the-best-tablet-displays-ipad-2-just-got-dethroned
I disagree with him though as I believe the transformer has a better and brighter screen than the Ipad 2.

I have both side by side and the iPad2 is clearly brighter at max, dimmer at min, and less reflective...

Any one else notice that this page has a caption next to the results: "Click to embiggen chart" ?
How can I take an article seriously if they use words that were made up on an episode of The Simpsons. I guess they would argue that their usage was perfectly cromulent.

The best one is the one that fits your eyes.

Right, I almost never use max brightness.
Also Transformer has 1.3 times more the number of iPad 2 pixels.

This guy knows his stuff, so I'd not be inclined to argue with him. However, I'll say this: the screen on my TF is outstanding, regardless of whether or not some other screen is better. It's like cars: I love my Infiniti G37, even though there are demonstrably better-performing cars available. And indeed, one of the things that I love about the G37 is that I paid $15K less for it than the equivalent BMW, and have 95% of the performance. That's an equation that I can live with quite happily...

ive seen other review of the screen(cant remember where) by a guy who knows alot about photography, he did all this measurement on the color and white balance on the k scale, and has said if your into professional photo applications the transformers screen is the best as it produces very accurate colors, also samsung had put a screen driver ontop of the tegra 2 one to over saturate colors to make the screen appear more vibrant but if your looking for image accuracy its a bad screen for that

I have done measurement of the transformer and iPad and find that both units have some inaccuracy, but are pretty close to the actual values when displaying a sample color panel. I would give a nod to Transformer for warmer (red and orange) colors and the iPad to colder (blues) colors. Both are miles more accurate than the Samsung which is dramatically over saturated.

My iPad's screen is too warm, and my TF's screen is too cool.
It's a bit frustrating.

Yeah, the color accuracy is great on this screen. It almost makes it painful to go back to my laptop.

Never have thought the TF had the best screen, way too many issues with light leak to even be considered. It looks aight though.

The Ipad is known for having light lead issues as well; it seems to be a "feature" of IPS panels. That does nothing, however, to detract from the fundamental quality of the screen when any light leakage isn't apparent (as in 100% of my own use, since I might have leakage but haven't even noticed it).

Tablets really need to have color profiles and brightness and contrast like you do on a Mac or PC. Then you could use a hardware calibrator to create a customize profile for the specific of your own display. I do this on all my laptops and desktop monitors and the results are very nice. The only downside is the calibrator hardware and software cost $250+.

i just had my screen replaced under warranty by asus for a white spot (backlight leak).
unless i'm imagining it, the new screen seems to be warmer and not quite so bright as the one it replaced
but it also has zero light bleed at the edges where the old one had quite a bit.
perhaps they're now using a different panel than when i first bought my b60 tf101 a year ago.
has anybody else noticed any variation in screen brightness/ colour between units?

Yeah Asus replaced mine too because it didn't wanna turn on. The new screen is magnificent no light bleed and yeah Asus Sammy and apple have the best screen

I can't complaint as asus renewed my screen cause of back light leaking. Im told that apple always use too many pixels looking at there screen resolutions.

I have TF101 (mid level bleed issues, I can live with them given I rarely run full brightness, never need to), iPad 1,2,3, A500, Nook Color, and a few others. IMO, ALL of the IPS displays are great, and more than safisfying. I don't compare them because I don't see the point, they are all way more than "good enough" for my and my family's casual use. If you are using these for photography or similar "on the road" and color accuracy is a concern, then you should probably get a Macbook or even better the new asus zen gen2 (which beats even the MAC displays for accuracy, check out Anand's review on the new Zen Ultrabook, drool ). My main point is, as long as your display makes you happy, who cares if there is another one out there that is better . If you are researching for a purchase on the other hand, be realistic in what your uses are going to be and read reviews that cover those uses along with reliability and customer support quality, see if you can borrow one or check one out somewhere, and let your budget and your eyes be your guide, and you will be happy with what you get.

How is THAT screen?

I created this thread specifically for all the members to talk about the new 2k screen of the LG G3. The screen is the most important feature of the LG G3 and it is what LG brags about the most. For many of us including me, the screen will be the deciding factor of whether we buy the phone or not.How does the new 2k display panel perform in real life situations compared to other high end phone display panels like the Galaxy S5 or HTC One M8? Let's have a nice dedicated thread to the most important feature on this phone.
Ideas to talk about:
•Contrast levels
•How your content looks on it
•Your thoughts of it compared to the previous display you had.
•Any weird issues? (Screen interlacing, ghost issues)
•Color production
•Do you find it nice and worthwhile?
•How are those BLACK LEVELS (Important!)
•Any heat issues with the screen?
•Good high and low brightness levels?

All of the above... Thinking of upgrading from a nexus 5...

I have seen a couple of reviews that say the max brightness is quite dim. Can someone who owns one confirm if this is true?
The G2 has the best display I have ever had and I don't want to downgrade to a duller screen (I am not bothered about the high res as the G2 has enough res. I want bright and vibrant!

Go to s5 ^^ it's too bright and too vibrant :laugh: (^^)

And ffs please, reviewers, don't simply declare that you can't distinguish individual pixels on 1080p as well as 2k and then conclude from that that the extra resolution doesn't make a difference. The question is: how do you subjectively experience visual items in 2k vs. 1080p--images, text, UI items, etc.. Past 325 dpi, a pixel is not an item, so it's irrelevant that you can't see one. Tons of those online reviews provide what the reviewer thinks their impression of the screen must be instead of the reviewer providing their true impression.

I don't like the s5. Various reasons but mainly the cover over the charging port and overall design.
I love my g2 but need more memory (64gb minimum). I am worried about the screen on the g3 but the reviewers all focus on the resolution but I want to hear from real users about the real world experience of the screen.
Many thanks in advance for any input from owners of the phone.

Great Arstechica review as usual
http://arstechnica.com/gadgets/2014/06/lg-g3-review-a-great-phone-with-way-too-many-pixels/

That cover on the S5 (my wife has one), is for water proofing and easily ripped off.
Personally, I could use a screen with less pixels and longer screen-on time. I consider the screen resolution to be a minus. My preference is less pixels and make it a 6", like the HTC One Max I just returned after a week.

Can't agree with you there. They did the same move as all the other reviewers where they presume that the inability to distinguish individual pixels automatically means people can't see any overall difference in image quality:
Even at point-blank range, it's hard to resolve a single pixel. 1080p screens are also beautiful, though, and when looking at the two, side-by-side, we aren't convinced the jump to 1440p is necessary. More pixels only matter if you can see them, and on a ~5-inch device, it's almost impossible to tell the difference between a 1080p screen and the 1440p screen of the G3.

That's why I asked above that any reviewers here avoid that particular groupthink and tell us how they actually experience 2k vs. 1080p.

I think the most important caveat is that hardly any apps will be optimized for 2k display when the phone finally arrives.
HAving said that, kind of hard to judge don't you think?

That's logical. But so is the idea that the human eye can't distinguish pixels at a density greater than 326dpi. So, yeah, it comes down to subjective judgment calls. In that case, I'm interested in the subjective point of view of people who actually have one of these devices and their actual experience. We already know how do deduce logically what everyone's experience must be, and all the reviews I've read only do that. Images and text may appear sharper at a given distance from the eye in a way unrelated to whether or not you can distinguish an individual pixel.

The LG G3 has the best smartphone display I've seen: It's sharp, but it's also bright and has great color. The colors don't pop quite as much as on some of the better SuperAMOLED screens I've seen (such as on the just-announced Samsung Galaxy Tab S), but the sharpness is off the charts.
Comparing the G3's display to the one on the HTC One M8 (my current favorite Android phone), I felt the LG's was just as sharp, and a few details — such as drop shadows in Evernote — stood out slightly more. And even though colors weren't as vivid as on the HTC, the G3 had more natural skin tones

From Mashable's review. Everyone's eyes are different I guess.
Contrast was superb. Black text on white background — one of the most essential things a smartphone, or any display, needs to get right — really stood out. The ultra-sharp characters nearly jumped off the screen, and I couldn't discern individual pixels, no matter how close I put my eye to the screen.
So the LG G3's Quad HD display is more than just hype. But only a bit. There's nothing wrong with the HTC One M8's screen — or the Samsung Galaxy S5's or the iPhone 5S's for that matter. They're still mighty sharp, and can display great images, just not quite as sharply or as impressively as the LG G3.

I truly hope that the screen is great on this phone but I can't wait any longer and have just ordered an S5. I have waited for all the flagships to come out this year and was truly hoping that the G3 would be the one. Two of the most important things to me are brightness and battery life and I'm worried that with the G3 I would end up having the brightness cranked all the time and would have poor battery life as a result. Really wanted to try LG this time but lost my nerve
Tapped it!

yes but not for marketing.

I'm most concerned with the viewing angles, black levels, contrast, and color accuracy. I'm definitely getting the G3 but I really don't want to have to play the panel lottery. I'd prefer a warmer display over a cooler display - as long as it's not noticeably pink/green/blue, I'm fine. A slight yellow/orange tint is okay, but obviously a calibrated display would be the best. My black Nexus 5's viewing angles aren't great, with the screen washing out at 30+ degree angle. My buddy's white Nexus 5 seems to have better viewing angles, so I'm not sure what the deal is. I'm pretty confident in LG's ability to produce good displays -- they pretty much made this phone just to show off their new display.

Actually, I'm now concerned about the narrowness of the bezel. Yes, it's a cool feature, and everyone dreams of a bezel-less phone, but I already have problems due to the narrowness of my S4's bezel. When I'm holding my phone for an extended time, referring to notes while speaking to people, my grip often gets interpreted by the system as a touch and hold. That pops up a dialog that I have to dismiss, and it's really obtrusive in real time situations. Sure, I could be more careful, but it's just too easy to make that problem happen during normal usage. It's not like I have big fat hands or a weird grip or anything. I've already been thinking that when we finally get bezel-free phones, there will have to be utilities to create a non-reactive border of pixels in a user-specified width, or else the user will accidentally be popping things up all over the place. At present, though, I think the G3's large size and tiny bezel are actually going to make it difficult to use the way I want to use it even though it's hardly bigger than my S4. You never know until you actually use it for a few days and try to adapt, but there's no way to do that without buying it, which I'm now hesitant to do.

You're holding it wrong ☺
