Colour contrast ratio ?

Hi everyone...
I've 3 phones...
Xperia arc S
HTC one X
Samsung Galaxy Nexus
Now when i compare any 1080p movie from you tube at full HQ n full brightness of the respective phones ... this is what i noticed...
HTC one S has the best colour combinations contrast ratio n colours..... second cones Sony xperia arc S ... n lastly came the Samsung Galaxy nexus....
The display on GN was quite not satisfying.. I dont know why.. but there wasn't good colour contrast in it.... the colours weren't rich as the other two...
DO YOU THINK THIS WILL BE THE SAME CASE IN THIS NEXUS 4 ?
Please discuss this or lemme know coz yes.. I'm just one another person thinking to buy Nexus 4..

I was just about to post a similar thread. GNex had the PenTile arrangement of pixels, and a SuperAMOLED Display (which had defects and all). But the Nexus 4 has a totally different display technology. I hope someone will be able to explain the difference (as I don't exactly know the difference myself).

Look at the Anandtech review (scroll 3/4th of the way down). The Nexus 4 is looking to have the highest contrast display they've ever tested, even higher than the One X.

S4 vs note 2

can anyone tell me which phone is best for gaming s4 or note 2?
Sent from my GT-I9000 using xda app-developers app

both are good..

Since 4 is obviously a bigger number than 2, I would test them both yourself and then decide which you like best.

Personally I will go for note2..
There isn't any game that lags in note2
Battery-3100mah, undoubtedly above good
processor-very good(quad core)
Ram-2gb (same as s4)
Why not s4? Here's why-
Expensive than note2
Poor battery compared to note2
Phone heats up very quickly on hard gaming(it becomes so hot u can't even touch it)
Small screen(depends on u)
Not actual octa core (2Xquad core)
Rest is ur decision..I investigated a lot before choosing among both and then bought note2

S4 is more powerful in benchmark results so i guess it will be good for gaming
5 inch screen is not too small lol and also screen resolution of S4 is 1020 while its 720 in note 2
S4 is easy to hold with one hand for one hand operation i.e typing/texting
the only advantage of note is bigger battery and extra 0.5 inch screen

S4 cause it has better CPU and more important a faaar better gpu(the essential part for gaming) that support also OpenGL 3.0 +better display.
Note 2 also has good points (bigger screen and better battery) but overall the s4 is better for games.

Well the S4 has more than twice as many pixels to shuffle around so it really needs the extra power. While the S4 has a sharper display (441ppi vs 265ppi) the Note2 is slightly bigger (5,5" vs 5.0"). If you have no need for the S-Pen I'd say, go with the S4... just make sure to keep a spare battery available.

Anyway I'd suggest you to wait for the s4 advanced,that will have a massively better gpu and a 20/25% better CPU(s800) or if you can get the the s4 lte-a (same as the s4 advanced but already on the market, HK and Korea only) that it is also 32gb ver.
IMO the best thing to do is wait a month to buy the s800 devices that will come out(Xperia z1,lg g2, note 3, nexus "5", and the htc one max)

The Note 2 has a bigger screen but less pixels, s4 a small screen with more pixels. So the video peformance is not very different because the s4 needs more power to manage those extra pixels. And of course personal preference.

simply wait for Note 3 :good:

The battery on the Note 2 will easily last more than a full day even if you use your phone a lot. When I had the s4 it struggled to get to the end of the day. The 1080p screen uses a lot more juice than the 720p on the Note.
S4 is more powerful for gaming though that being said the Note 2 is still a beast.

I've said this before, and I'll say this again,. you won't notice a difference in 720p vs 1080p unless you obsess over it and has a perfect vision. I have seen nothing different comparing both hand in hand, text is slightly crisper if you are being very anal about it. What you ought to consider though is price, if you use it for gaming, and the screen real estate vs one handed use.

But you have to consider that most games are played at 720p even on the sgs4 so the difference(even at native resolution) is huge.

Actually the case is not as simple as "1080p is 2.25 times more pixels than 720p"..
Let's count Sub-pixels on Note 2; there are 3 sub-pixel for each pixel thus giving us the number of 3 x 720 x 1280 = 2764800
Let's count sub-pixels on S4; there are one blue sub-pixel for every pixel and there are one red and green sub-pixel for every two! pixels giving us the number 1920 x 1080 = 2073600 blue sub-pixels, 1920 x 1080 x 2(for red+green)/2(for sub-pixel sharing)=2073600.
In total = 2073600+2073600=4147200 sub-pixels.
The expected ratio= 2.25
The real ratio= 4147200/2764800=1.5
Still, the GPU has to push every image rendering for a 1080p calculation. This is why the power is wasted. It calculates everything 2.25 times more than a 720p GPU just to be able to draw it inon a 1.5 times sharper screen.
I am not against a 720p pentile screen because it pushes the 300ppi barrier so it can be more sharper for human eye in certain conditions, however a 1080p pentile screen with a "false/fake" 441ppi is just overkill for both the battery and the GPU..

I had the same choice. But am not a big gamer.
Went for the note 2 because:
- better battery
- bigger screen
- S pen
- cheaper

There are obvious (minor) plusses and minuses to either one in terms of gaming. I think you should take everything that's been said and determine whats most important for you to have...bigger screen, more pixels, better CPU, etc. I game but wouldn't classify myself as a big gamer...I've used both and I think the experience is comparable.

For me is better Note 2 for play.. The bigger screen is a big help and is different to see. My friend, when they see me to play, say that like a different phone that theirs HTC one or GS4.. And also, with the same game, i don't see difference about power...

Get a PS3 or an XBOX 360

Ive gone to s4 from note 2. Not much difference gaming at the min. The screen is brighter on s4 and is sharper but I still miss note 2. Although im feeling better with size in pocket and like design better.
Would I go back to note 2? Yes easily.
Ps battery lasts all day on s4

Do you like to use MHL to output your phone's screen to a TV? If so, I very briefly got to try my Note 2 vs an S4 a few days ago and the latter struggled in Epic Citadel (as an example). In general terms the Note 2 felt slightly smoother everywhere when using MHL too (although the S4 can power the MHL adapter by itself which was quite a cool feature, though obviously the battery nose dived pretty quickly!).

Note3 has the brightest display ever?

Just saw this:
http://www.androidauthority.com/note-3-display-review-brightness-display-mate-278726/
http://www.displaymate.com/Galaxy_Note3_ShootOut_1.htm
Is this legit or did Samsung give them a super-model for their lab test? I like to believe it, but it sounds a bit of a stretch...
The Note 3’s is extremely bright. According to DisplayMate’s testing, the Note 3 is 55 percent brighter than the Note 2 and 25 percent brighter than the Galaxy S4. The Note 3 performs better than or comparable to “most LCD displays in this size class”. With Automatic Brightness on, the Note 3’s display reaches an impressive 660 cd/m2, which is the highest value that DisplayMate ever recorded. For comparison, the iPhone 5, long considered a standard in display quality, outputs 600 cd/m2.
DisplayMate praises the user selectable color modes of the Note 3, noting that the Professional Photo mode delivers a “fairly accurate calibration to the Adobe RGB standard, which is rarely available in consumers displays”.
The reflectance levels on the Note 3 are very low, which, along with the high brightness, improves readability under intense ambient light. The Note 3 has the highest “Contrast Rating for High Ambient Light” that the company ever measured.
At viewing angles of 30 degrees, the display loses just 22 percent of its brightness, compared to 55 percent or greater in the case of a typical LCD display.

Do you have something meaningful to say? I'm just wondering how an OLED display can be brighter than an LCD one (by nature of the technology used, LCDs are brighter).
From gsmarena:
The Super AMOLED panel on the Galaxy Note 3 isn't the brightest we've seen and it's inferior to the Galaxy S4 in this department. However in most cases you won't notice this in practice unless you pit the Note 3 side by side with an HTC One or iPhone 5.

Not sure where you got that info from. Personally, i'd go for numbers from displaymate over gsmarena.
For reference, Displaymate's Measured Peak Brightness numbers are:
Galaxy SIII: 283 cd/m2
Galaxy Note II: 353 cd/m2
Galaxy S4: 475 cd/m2
iPhone 5: 556 cd/m2
Galaxy Note 3: 660 cd/m2
gsmarena don't have any actual numbers.

Actually, they do. It's on page 2. They've put them in a table and everything, so it must be legit, right?
Anyways, I think I figured out the disparity between the two sites. Gsmarena measured brightness at manual brightness setting at 50% and 100% setting. Displaymate measured it on Autobrightness to achieve c660 cd/m2. So, assuming this is correct, Note3 can achieve far higher brightness levels on its Auto brightness than adjusting the brightness manually.

I wonder if they do that so people don't jack up the brightness too far and leave it there and burn out their AMOLED screen too fast. Meanwhile auto-brightness goes into asskicking mode when in bright sun but then comes back down to sustainable levels as soon as possible.

So you trust GSMarena which don't have tool or experts to do these kind of testings over trusted corporation which main job is optimizing, calibrating, testing, evaluating and comparing all types of displays, monitors, projectors, mobile displays, HDTVs, and all display technologies, such as LCD, OLED, 3D, LED, LCoS, Plasma, DLP and CRT
Cool

I doubt it has the brightest screens of all cellphones out there. The WhiteMagic screen of the Sony Xperia P is over 800nits.

That's what I said. They don't have a number for auto brightness, which is the only way to measure max brightness

Note 3 1080p Pentile Display

is only slightly better than Note 2's non-pentile 720p display.
As a former Note 2 user, I tell you this:
To avoid further disappointment, please do not compare it with iphone 5's display.
Thank you Samsung!

As a current Note 3/Note 2 user, I completely disagree.

As a former Note II user I think you're out of your mind.
Here's text from both.

N3
Here's a detailed review from DisplayMate who makes the equipment all OEMs that use displays in their products use to test them.
The Galaxy Note 3 has the newest generation of OLED display technology. The Lab tests show that it is better than the Note II in every measurement category, and also comparable or better than the display on the Galaxy S4. It has double the resolution of the Note II, which is a major improvement, but the most impressive advancement for the Note 3 is its significantly brighter screen, which hits an incredible 660 cd/m2 in high ambient light, the brightest mobile display we have ever tested in the Shoot-Out series. An impressive achievement for OLEDs!
OLEDs need to continue improving their power efficiency, which is critically important for mobile displays. We measured an impressive 26 percent improvement in power efficiency between the Galaxy Note 3 and Note II. While LCDs remain more power efficient for images with mostly white content (like text screens, for example), OLEDs are more efficient for darker content because they are emissive rather than transmissive like LCDs. In fact, Galaxy Note 3 is already 31 percent more power efficient than the Full HD LCD Smartphones we recently tested for mixed image content (that includes photos and videos, for example) with a 50 percent Average Picture Level, APL. If this keeps up then OLEDs may pull ahead of LCDs in total power efficiency in the near future…​

Why don't you return your Note 3 and get an iPhone then? I don't understand the need for this thread besides trying to annoy everyone who is enjoying their recent purchase.

dude its makes the note 2 screen look like a piece of ****. no more black crush. and clear. theres def something wrong with u lol

OP, post a time stamped pic of your Note 3 and Note 2 preferably.
I think someone is trolling......

Dude is dumb. Girlfriend has the iphone and I have note 3 coming from note 2. Firstly compared to note 2 it's like comparing ps3 to Sega Genesis. The crystal clarity of the 3 awws even iphone users. My girlfriend realized (after looking at my phone) there is not a thing that her phone does better than mine.

How bright is it?

I've read reviews that claim:
- Not as bright as the Note 5
- Just as bright as the Note 5
- As dim as the Nexus 6 (last years)
- Dim, but bright when adaptive brightness turned off.
So, anyone know for sure? A cd/m2 measurement would be great. The brightness of the original Nexus 6 was a big disappointment.

Friends on what you consider dim/bright to be.
Majority say no problem in bright sun, so it's "bright" enough.

There is an app for the Nexus 6 to blast the screen real bright when outdoors. I have not tried it, but I've read ppl like it. If the P is not bright enough I'm sure an app will be available for cranking the brightness up.

356 nits ....but im hoping it can be more based on many of the (almost as bright as note 5)
Nexus 6 was 270.....so much broghter than last year, but much dimmer than note 5.
By Much i mean 30% more than last year but 30% less than note 5.....

I think it should be fine. Nexus 5 is 400 but I have never turned it above 75% even outdoors. 356 would be at the high end but I have no worries about it.

Brightness seems to be pretty sad unfortunately :-/
http://www.phonearena.com/reviews/Google-Nexus-6P-Review_id4110
Another thing we have to point out is its poor visibility outdoors when the sun is present – it washes out tremendously to the point that it’s unusable unless we shield it. Achieving a maximum luminance of 356 nits, it’s not as potent as the Nexus 5X mark of 487 nits, and nowhere close to the blinding 593 nits reached by the iPhone 6s Plus.

I heard you turn off adaptive brightness mode and the phone gets brighter, like it said above.

Wait this is less brighter than the LG G3.......and the LG G4 is the one I have and it's the darkest most uncomfortable handset to use with minimal sun.... wtf??? *cancels order* I'm just gonna wait for nexus I/O 2017 this is horrible... but I doesn't make sense why every reviewer says it's the brightest screen they've seen thus far....smh

You have to take into account that brightness isn't the only thing that matter for readability under very high ambient luminosity.
Screen reflectivity, contrast and color saturation are as important as brightness. And the LG G4 (like most of the LCD) is very reflective, not even close to an AMOLED in contrast and can't achieve the same saturation that what is possible with an AMOLED panel.
In fact, if you go read a GSMArena review, you will see that under direct sunlight, the G4 isfar less readable than a Motorola Nexus 6...

Reflectivity etc is important, I agree. But I am hoping that the nits readings are with the standard adaptive brightness etc on. The mid 300s isn't as great as I'd like, and is around the overall average.
Nevertheless, the UK winter is coming and sunlight readability becomes a moot point!

I agree that 350nits is average at best.
But the biggest problem, IMO, is that the display on the 6P seems to be not as close to the glass as the latest Samsung devices. This will lead to an higher reflectivity.

Very poor brightness
Just got the 6P. Don't like the brightness at all. Am coming from the G3 and it's really sad. The Galaxy S6 is awesome. I always keep the phone at max brightness. Damn the battery, I say. I thought initially that perhaps the adaptive brightness setting was enabled. But it's not.
On paper it's brighter than the Nexus 6. But looking at them side by side, I don't see it even remotely brighter.
I hope that it's not really a limitation in the hardware and can be increased with a software mod.

i just walked outside in california sun at 1:00pm. i can read texts just fine. might have hard time looking at dark images because well black is...not lit... but i rather have little dimmer screen to preserve battery life and plus less prone to burn-ins.
