I have two Nexus S at the moment and they both have significantly different screen rendering while running the same ROM with the same customizations and brightness. This shows up most clearly with the wpclock wallpaper. I took a screen shot of each to post in the wpclock thread to see which of the renderings was most similar to other people's screens. The screen shots for both phones looks the same on my monitor, which I guess makes sense because a screen shot is a representation of the data of the picture and not an actual picture of the rendering on the screen.
Is my most accurate NS as far as screen color goes the one that matches the screen shot on my monitor? This assumes my monitor is fairly decent. I need to return one of the NS and I really don't know which is the more accurate screen rendering, one looks saturated with red and the other looks saturated with blue.
I had only looked at the phones individually before and thought the screen looked great on both, so it's really not that big a deal. When I looked at them together I noticed that they rendered quite differently and the red saturated one is slightly brighter than the blue saturated one. The red one has only been used for a few hours and the blue one for almost 30 days.
replying directly to the topic tittle question
i'd say no
the screeshot is capture within the machine, it will always show the correct color even if the physical device (screen) is not displaying the correct color
there have been very few SAMOLED screen that came defective from factory (from SGS)
but so far we've not see that as of yet in the SNS
^^ Thanks for the reply.
I found some good information in this thread, in particular post #7: http://forum.xda-developers.com/showthread.php?t=883109
We can probably close this thread.
I have 2 Dell 22 inch LCDs here bought them at the same time and the colors are slightly different between the two.
my point being is that monitors and such display colors differently,
hi,
i just started this thread to get your opinions regarding the display quality of the note3!
i have to admit upfront that i'm a hypocrite when it comes to amoled screens, so far i had to switch all of my amoled devices a least 5 times until i got a unit which satisfied me. done this with the first note, and also with the second.
as far as i can say the screen of the note3 is the best i've ever seen (by far better black-levels as note1 and note2), although i also identified a few flaws as well:
the color RED has very bad viewing angles: when tilting the device a little bit the color gets orange immediately.
try this by enter *#0*# in the dialer, and click on "red" then tilt the device. let us know how "your red" is, thx!
the gamma of the screen is totally screwed: can see down to "1" in gammatest.png:
the disadvantage of this is that you are actually able to see dark grey screens which you should not.
on the left side of the screen border there is a small strip which has also more gamma then the rest of the screen, in menus etc.
this is clearly visible when its dark around. also only visible when at least a little grey is to display, pure black is ok!
this week i will test one or two more note3's, just to have a comparison and to determine if the quality spread is as big as with previous devices. for note1 and note2 the differences between devices were really huge. some screens were near to perfect, most of them had flaws with color unevenness.
what are your impressions?
and: do you care?
regards,
markus
edit 03.10.2013:
just got my second note (this time from amazon.de): the screen is considerably better!! the "more gamma" strip on the left side is non existent on the second device, in gammatest.png the screen is much more uniform! also the red viewing angle is better, it still fades to orange when tilted, but not as much as with my first device!
conclusio: the big differences in screen quality are still existant, it's still luck of the draw if you get a decent one or not...
also the general build quality differs: on the second device the pcb is not exactly in the middle of the casing, the camera hole is not centered in it's protrusion, and the power button extends a little more out of the casing.
again, i may be a "little" freaky about this things, but for > €700 I want to have a decent device!
screen quality is very important for me, because i read a lot with the device, especially in dark environments where the left gamma strip i mentioned was really annoying! i also showed this to a few colleagues of mine, and they agreed.
edit 04.10.2013:
another finding: when CPU load is high, the brightness jumps between a lower (darker) and a higher (brighter) state, even if brightness is set to manual: both devices show this behavior, although not exactly identically: my first device needs more load to start with this (it takes longer), the second one starts the dimming relatively early.
how to test: load a stress test tool (cpu prime benchmark from google play) and let it run, set the brightness to manual maximum and wait.
you will see that after a few seconds the screen will go darker, and will switch between this states. this is independent from the brightness level, it is only better seen at maximum!
i guess this is some power and/or thermal limitation (when more cores are under heavy load), it would be interesting how this kicks in in summer when ambient temperatures are higher...
edit 25.10.2013:
just to let you know: i'm now through 6 devices, all of them had display flaws in terms of uneveness.
a issue most of the devices suffer is the lower dark half of the screen: on 4 of my 6 note3's the lower half of the screen has been signifcantly darker then t´he upper half,
one had a very bad gamme increase on the left 2mm, one had a bad gamma increase on the top 2cm. 4 had a warmer white, two of them were more cold (more blue). could be due to missing or wrong factory calibration...
what is gone is the "blotch issue" i had with sgs2, note1 and note2, and: black is now really black!
but on dark grey levels the uneveness is clearly visible, look at the attached "gammatest.png"
this shows the lowest grey tones. and should be a very visible gradient from top to bottom.
go in a totally dark room, open the pic, zoom in max, and navigate to the top left corner. then pull the
picture down, and look how the numbers fade. for example: "6" should be at the same brightness level on top
and bottom of the screen. it definitely is not...
go out and test for yourself, and post your findings!
Hi there, I should be receiving my N3 next Wednesday. Are the blacks the 'true blacks', as in taking the phone in a pitch black room and blacks cannot be seen?

OLED screens are the only ones I know of that can get true black. With OLED the pixels make there own light so no back light is needed, thus black pixels are not being used at all so a black image has a nice inky black color. You notice it the best when you have a colorful picture with black in it.

sorry, but this is a wrong statement. all amoled screens so far were NOT totally black, even if you displayed a totally black image! the reason is that if the screen is active the display controller is powered (which is the case when displaying a black image, and not if the screen is "off") which can be seen as a faint and VERY dark glow. you can only see this when the room in which you are is totally dark, and your eyes had time to accommodate. to make it worse: on all AMOLED devices i've seen so far there were patterns (like hair lines and blotches) in this grey glow, due to the manufacturing technique used (lithography).
see for reference:

and so on...
so the question of cd993 is reasonable!
answer: note3 is the first device where i cannot see this dark glow, even in a total dark room! so a big improvement on this side. not sure what they changed, but the glow is definitely gone!
Red turns orange here to, but it doesent bother me as the screen is nice overall. Much better than my note 2
Red turns orange when screen is tilted, yes. Black are true blacks in Note 3. If you go to a pitch black room, and display a completely black screen in Note3, the phone will blend in and disappear.
Thanks guys, cannot wait to receive my device!!

Please make a quick guide of what to test and what to look for on a new note 3, in order to decide whether or not to return or warranty claim. Basically: On arrival, what would you check for, and what result would make you return it and get a replacement? How much of any issue would be ok for you to keep it..?
N3 screen : brighter and look better than Note 2 and S4 but still can not compare to the best IPS screen about white color

You'll do that with any Android phone whether LCD or AMOLED because their screens aren't individually calibrated (iPhone's are). So there's some degree of acceptable production tolerances that means all built won't be identical. So whatevery you went through before you'll go through again with the N3.
Oled = true black
LCD = true white

Today I got my N3 and all I can say its SUPERB!!! Abs everything
My only concern with AMOLED is the blotches that show on a grey screen in a dark environment like the first time I noticed it using Facebook. I had to replace my first Note II and even the second has some blotches but not quite as big and bad.
I've attached a grey background for your convenience to see if your AMOLED has blotches. You'll need to be in a dark environment like reading at night without the lights on (simulate by going into the bathroom and turning off the light).

You only see them in a pitch black room but I think they are the same thing.

Pointing out to OP that the leaking light on the Note 2 (and s3) is extremely reduced in the S4 and Note 3 - you should not compare the Note 3 with the Note 2 in that aspect.
Black wallpaper on n3 = better battery life then?
Other than seeing imperfections in impractical situations, is there anything about the display that is actually bad in normal use? I mean do you see whites on this phone and think, hmm that's more of an off-white or is it like so small in difference that you need a color spectrometer to prove that it's not "true" white?

I know what you mean. I had that on my note 2. Not so on my note 3. When I open black screen in a pitch black room, the phone becomes completely invisible as it blends in perfectly with the dark. And yes, I'm not exaggerating. It's the deepest black I've ever seen on any display, it's like the phone is actually turned off.

Hi Guys!
Need info about PURPLE SEMARING. Does the Note 3 has this issue? Because all the S4 has this semaring issue although it has a pitch black. Please confirm this purple smearing. If it's totally pitch black and without smearing it will be the perfect screen out there
Thanks guys! :highfive:

Got my OnePlus last night and generally I love it. But I have one showstopper that I'm hoping has a fix that I just don't know about. Is there something wrong with my phone, or is there a fix, or is the problem with me that I’ve become perverted by AMOLED?
See, I use my phone to read at night before bed. Lights totally off, and the black background is just not black, it's grey. My last two phones are a Galaxy S4 and Galaxy Nexus, both of which have AMOLED screens. From what I've read, the AMOLED has a very deep black because apparently the lighting is per-pixel, so the pixel is literally not even on when black is on the screen, right?
So when I read at night, the lit pixels are a deep amber orange, and the black pixels are...black. On the OnePlus, the deep amber orange is washed out (comparatively), and the black pixels are...grey. This is pretty much indistinguishable if there's any visible light in the room, but at night with all the lights off, it’s very obvious since I’m used to the AMOLED black. This shows up in both my ebook reader, Moon+, and in Chrome and Gallery when downloading a "pure black" photo. I even use a program, Screen Filter, to dim the screen down below the lowest brightness setting, but the black background is still too bright for me. And yes, it’s there without Screen Filter.
Again from my reading on this, I seem to find that LCD screens (which the OnePlus has) light the whole screen for their backlight, so this may be pretty much inevitable. Is this accurate?
I’d post a photo, but in the kind of low light conditions I’m talking about, no photo would show that kind of contrast. At least no photo I know how to take.
PS - This does not appear to be the "yellow screen" problem I've been reading about. The colors seem consistent from top to bottom. But I'm not very good at color distinguishing.
Any help is appreciated! Thanks!
You're just used to AMOLED displays, the blacks on those are much deeper because it's not actually lighting up when it's displaying black, it's displaying nothing at all. This is because there's no backlight, each pixel is made up of three LED's, so when it's displaying black none of those LED's are firing up. An LCD display is completely different, even when it isn't really displaying anything (black) it's being lit up by the backlight. There's nothing you can do about this.

What he said.... the OP can adjust his screen settings accordingly to emulate a "AMOLED" experience as previous phones such as N4,N5 has done this.
http://forum.xda-developers.com/showpost.php?p=54321008&postcount=6 try those settings it might satisfy the OP when it comes to blacks being blacks and not gray
I bought H959 yesterday and I test the display function after I open the device.
I found that the LG POLED has serious mura (uniformity problem) on low level gray scale pattern.
I know OLED process for LG is still tough so I can accept this defect. But I want to know everyone's phone also has this defect or not?
If it's just a special case, I will try to change a new one.
I compare this with my wife's S6 edge in the same pattern and don't find this phenomenon. I still try to catch the pictures because it's hard to get this kind of pictures.
Sorry, my english is pretty basic.
Sorry to say but this is normal. The screen uniformity is terrible in gray which is likely why LG has set such a high minimum brightness so that it is not easily visible in other colors.

A lot of people have yellow spots visible in grey font with 0 brightness
I can confirm having small yellowish tints and terrible gray background quality. It looks like it's made 50 shades of grey squares xD I don't really mind, just stop thinking about it and look at the curves and beautiful deep blacks of the display.

I totally aggree!!!
Same issue here. The uniformity problem reduce if you increase the brightness.
I noticed that when I have Always On display at maximum brightness, the device turns on many random white pixels in the area that was supposed to be black, kind of simulating a LCD backlight.
It is noticeable by exposing the sleeping phone to a bright light so it will go to maximum brightness while Always On, then turning off the lights while the brightness is at maximum you can see the "backlight" (white pixels in the black area). As soon the phone adjusts the brightness you can't see it any more.
Here are some pictures, comparing maximum brightness, low brightness and also comparing to a S8.

Please note that by taking a picture makes it more evident, in reality it looks just like a LCD backlight, not a star constellation like in the picture. Even though it is not bad in reality I am concerned because this should not happen in a black screen in an OLED display right?
I tried replicating this with a regular image and I cannot, I can only see it while in Always On display.
Anyone else having similar issues with the regular Pixel 2? Or even in the 2 XL? I did not notice this happening when I had the 2 XL.
My blacks have always had that LCD type backlight look. I was wondering the same thing but I've seen others with it so I just assume it's the design. Not keen on it but it's not the end of the world for me
To me it only happens in always on display. If I have a black picture on my screen it doesn't show this "backlight"
