I wanted to branch out from the other thread and actually do a poll to see how many people are experiencing this problem, and how severely. In the other thread (http://forum.xda-developers.com/showthread.php?t=1515299), several people claim that their copies are absolutely perfect and show no signs of black crush. If you indeed have a "good" screen, your feedback will be incredibly valuable. Please post pictures of your phone, if you do the test below and the blacks display correctly!
The reason that most of us are seeing "black crush" or ugly blockiness in dark areas in videos and photos is that these artifacts are present in the source material. Blocky patterns are a result of compression, and are most noticeable at the extreme ends of the dynamic range, where there is the least amount of detail. So if these compression artifacts are present in the source material, why do we not see it on other devices? It is because most other displays are properly calibrated to gradually gradate dark tones from dark gray to black. In other words, on a properly calibrated display, the color #000000 (black, or RGB 0,0,0) is virtually in distinguishable from #010101 (RGB 1,1,1). In fact, it is hard to tell a difference until #050505 (RGB 5,5,5). Therefore, most of the clipping that occurs as a result of compression artifacts is hidden. However, with the Note, #010101 is very much distinguishable from #000000. Dark tones are too bright, and we're able to see clearly until #010101. Instead of gradually moving to black, at #000000, it drops off a cliff. This is why we see such a dramatic different between the darkest grays and blacks, and why this black crush issue is so noticeable.
The side effect of having grays that are too bright is that when watching Blu-ray quality HD video, the dark areas look washed out, and the picture lacks "punch". High quality video that is properly encoded very rarely have pure blacks (to avoid clipping). As a result, dark scenes appear too bright on our phones.
The method to test is with a gamma test pattern, which I have attached. Download QuickPic from Market/Play (free). Go to Settings -> Viewer, and check the box for 32-bit render. Then, download the attached .png file, and view it in full screen in QuickPic. Make sure to do this in a DARK room!
Each box with a number has a corresponding RGB value. For example, the box with the number 1 is RGB 1,1,1, and so on. Load it on your Note and report back the smallest number that you are able to see. Also, does it gradually go to black, or does it just abruptly go to black without a smooth transition?
Last week, I went to two AT&T stores, and tested every display model with this method. Even with the bright store lights, it was possible to see box #1 on every phone. Repeated the test on an iPad 2, Galaxy Tab 10.1, and Skyrocket. The iPad was too dark, as the entire left side of the test picture is unreadable. On the Galaxy Tab, I could see box #7 or so. The Skyrocket showed a similar problem to the Note, as it seemed to abruptly transition to black. However, it was still a bit smoother than the Note, and box #4 was the smallest I could see.
Here's a picture of the test on my phone. The right side is the test image itself, so you can see how it is supposed to look like on your computer screen. Compare this with what you see on your phones.

I'm not sure exchanging it will do anything. Like I said, I have tried 5 different display models. I have also had 2 Notes myself, so that's 7 copies total and they all exhibit this issue. When people watch a video, like starfield 720p and claim that it's "perfect", that can be subjective. But if you're able to clearly see the box with the number 1, and is dramatically different from the black box above it, then you can objectively conclude that the device has a problem. If you go exchange it, and get lucky, report back. One of the things I want to find out is what percentage of Notes (if any) display dark tones correctly.

Make sure to test with the attached .png file. Like I said, watching a video can be subjective. If you open up the test image in full screen and can see all the way to the number 1, then the videos may "look" better, but the underlying problem still exists.

Thanks for your input. I am going to show this to ATT and see if they can let me test the note's and hope to find one that is better. There has been some luck with others in the other threads posted. I hope I can get one that is better or Samsung fixes the problems. I saw the clipping problem for the first time on a 2gig 720p copy of Killer Elite and I was so mad that my new phone has this problem.
****, I never realized an issue, but I did the test and it looks like the picture of your phone. I can see all the numbers on the left.
Mine looks just like yours... so I guess I am severe
Test does look quite different depending on how much you turn up the brightness, but either way I can see all the numbers.
Edit: but no way in hell am I returning it for a model that runs hot, is laggy, purple blotches, or whatever other issues people complain about around here.
See on mine i can barely see the numbers on the left
Has anyone found a larger version of the test pic? 400x640 seems too small

Are you doing this in a dark room, and viewing the image in full screen using QuickPic as I suggested? The resolution doesn't matter, as these are solid blocks of color. When you display it on full screen, it will stretch to cover your screen.

Yeah, I was in the living room and looked and thought there was no problem, until I went into the bathroom with all the lights off...then it was clear as day.
So what can we do to fix this?
The Pic on my phone looks exactly like the one you show in the 1st post on the left I can clearly see all the way to #1.
So what can we do to fix this if there is anything that can be done or should we send our Notes back to Samsung?
I can see all the way down to 1 and this is my 4 phone. The black clipping issue is almost non existent on my phone. Don't know if this test is accurate.

As of now, there is no known fix. Supercurio has been working on a fix for this since January. I have linked his thread below. The purpose of this thread, like I said, is to create an objective method of checking if black clipping exists on your device. This is a reliable and easy way of reproducing the issue, with the hope that you can easily demonstrate this to an AT&T or Samsung rep.

If you can see all the way down to 1, then your phone definitely has the black clipping issue. As I said before, watching a video is subjective. I can download the starfield 720p video with tubemate, and it will look great - but that's because the blacks in the video are pure black. With a real world video, this will not be the case.
When you see the box with RGB values of 1,1,1 and it is dramatically different than the top left box with RGB values of 0,0,0, then your phone exhibits the problem. If you still have doubts, go create your own image, and fill in half with RGB 1,1,1 and the other half with RGB 0,0,0. Put it on your phone and you will see a huge difference. On a properly calibrated display, the difference should not be discernible. Try it on other devices (TV, laptop, monitor, other phones, whatever), and you will see what I mean.
Read Supercurio's description of the problem in his thread: http://forum.xda-developers.com/showthread.php?t=1430847
He says, "Worst offender being shadows rendering: my diagnostic: what's supposed to be dark is not so dark.. and then boom its black (ie black clipping)
As a result color look dull, some UI elements show not quite as they're supposed to, and videos exhibit awful banding, blocking and ringing artifacts."
This is an accurate description of what we are all experiencing, and this test simply proves his hypothesis. I don't see how such a simple and objective test can be disputed as inaccurate.
The phone I have shows minimal black crush compared to the others three notes I had. But I just tried this test on my monitor and it barely shows 21 and 22. On my phone it shows to 1 and I thought my phone was almost perfect. Its ok I am very happy with the one I got until if any fix comes.
Mad as Pete
What does Samsung have to say about this? Are they aware of the issue? Are they working on a fix? Will it be fixed on the new ICS Galaxy suite update? Do we have to wait for AT&T to get fix from samsung and then wait another 4 months for AT&T to send it out us? Is AT&T aware of the issue? Has anyone told PhoneArena, Android Police, or contacted the Press and Media? Should I justt return my Note and never buy Samsung again? This makes me really mad the N7000 was released back in Oct and has this issue and it still has not been addressed? We spend $650 for a phone because of the big display and it has black clipping?
When I open up the test screen using the browser, the resulting image looks pretty good with the gradual black fade to nothing. but using quickpic and gallery, it shows the clipping. What's the difference?

I'm also the proud owner of a samsung galaxy s2. However, when it comes to new devices, everything i buy, i want to know if everything is correct!
Now i came across these pics on another forum i visit. But I appreciate this forum more(was only reading untill now), as I can see alot of the people are like me here. Exploring every little thing that could be wrong with the phone and not saying it's annoying to ask a lot of questions.
Now this is the problem i came across, haven't seen it anywhere else here, tough i read somewhere else abouth a blue-ish tint on the screen.
These next pictures have the same brightness, and all the same display settings too! So no lcd automatic power management(i don't know the right english word).

As you can see here the right picture has slightly "harder" colours. But it seems like the left had more contrast. The yellow lines stay yellow on the left one, on the right it's orange allready.
Left one clearly blue ish shine.
Now as I hold my own phone in the same positions as the picture standpoints, i can see mine is also like the blue-ish one with whole white screens.
Can anybody check this on their phone, as I now am worrying wich one is the one Samsung intended it to be?
Also a little other question, does this "automatic screenpower adapting" also changes the whites more to grey on your phones? When i turned it off it changed alot.
I've also seen those pics on Tweakers and checked my screen but I don't see any blueish hue on my screen. However it's hard to check because I don't know how the "other" screen looks like in real life.
Most people won't be able to notice the blue-ish hint on their screens without having another non blueish screen for reference. But I've had 4 Galaxy S2's pass through my ownership, and all of them have this blue-ish tint.

Yeah i know, wouldn't have noticed it myself. But just by comparing my phone to the blue ish one, i could see mine was like the blue ish one immediatly.
The other one has more of the pink hue like more of the lcd screens is guess...
What causses the difference, is it just some little layer?
Do you think we can talk abouth one of them being broken?

I can tell you that, in real life, mine looks like like the blue-ish one from those angles. However when i look straight on to the phone it's not like that, it's pretty white, like the 3rd picture but without the blue in the left corner.
It's taken with a good camera.
It's not broken. I'm convinced it's a software problem. The colour temperature is set incorrectly, it's too 'cold'.
If you load up a video in the stock video player app, then go into the settings menu, and make a mental note of the white colour of the menu, then go into colour tone, and set it to 'warm', notice the menu now has a much more neutral white and isn't as blue? Unfortunately the colour tone settings set in the video player isn't saved for else where on the phone.

Thanks, but doesn't change much. It's just a sort of coating. When i just turn it to idle, and i reflect in in outdoor light, I can see some sort off the same blue ish hue on it... You can test it like this...
So very strange what it is...
Ah yeah I see.
Well my other theory is that due to the way AMOLED displays work, as we all know they die out over time, getting increasingly dull with age. But with AMOLEDs, blue pixels have a much shorter lifetime than the Red/Green pixels.
SO my theory is that either there is blue 'cast/coating' over the screen or that the blue pixels have simply much boosted 'intensity', so that over time as the blue pixels age quicker than the other pixels over time, this blue cast/coating/boosted intensity will mean that the blues will still match the other pixels as they age much slower.
Didn't Supercurio release a color fix in his Voodoo kernel for SGS ? I guess you'll need to wait for a similar fix for the SGS 2 series .

I tried that personally, changing it from Standard to Movie helped the problem a fair bit, but it's still there. Dynamic didn't seem to make much difference.
Hmm. Could it be a software problem? Have you tried reflashing it? Or maybe its the problem with the Gorilla Glass.
Does anyone know if the phones in those comparison pictures are both retail? Maybe one is a proto

Phones from a couple from holland. Posted on tweakers.net.
Anybody compared their phone from those viewing points? And see if the blue ish hue is visible?
Hmm it seems the difference is there. My phone is with my friend and his phone is less brighter than mine. This maybe because he has used his phone while mine is new.
Gutted...
I hadn't heard about this but my SGS2 is definitely Blue-ish compared to a white screen on my laptop LCD :-(
Can you take them back and get replaced on this? (I have also put a small but deep scratch in mine, so hoping this would be basis for a replacement)
boch501
Well I brought mine back to the store for a refund, it's just too annoying for me.
Especially when you put it to an angle. The screen of my galaxy s 1 is far superior in this respect
I will wait for a newer batch to see if the problems are solved. I do read very little about this problem, does that mean it's just a problem with few devices or most people just don't care/notice it?
Any news about not-blueish displays?
Is there any possibility to find a near white perfect display, or all display suffers of the same bluish issue? (yesterday I've checked a pair of samples here in Italy, and both were quite blu in my opinion)
I've read that blu oled pixel lifetime is lower than other colors, so Samsung could intentionally push blu pixel in order to compensate color balance in the long term.
Also Gorilla Glass is a bit bluish, so it could contribute to increase the overall blue dominant.

But I am deffinatly sure that my blue tint is not coming from the screen. When i turn my screen off and reflect it in some light and play with it, i can clearly see that it still is blue...
Here are some pictures taken from engadget... You can see it here.
This one shows it....
Uploaded with ImageShack.us
This one does not. So look carefully.
Ever since the .33 update my screen colors look like they did when the tab was in power save mode (on the original firmware). This still occurs with ICS and I have tried a factory reset and it has not worked.
My reds appear to be orange. When looking at my thunderbolt's screen, the colors look much more saturated (and a lot better) in comparison. This was not the case when I first got the tablet.
Is anyone aware of a fix for this issue? I bought from gamestop on Dec 21, so I think I might be able to exchange it if necessary, unless there is a fix.
Although I don't experience none of these and my display looks great, I'd say just return it. If you truly feel that's the case, just exchange it then. Chances are very high next device won't have issue. Another person brought same issue up before but he was like the only one experiencing it. Everyone else who came into thread said everything was fine with theirs. plus interpretations of colors are subjective to each person. Not everyone sees things exactly the same. what may seem orangish to you may be deep red to the next man. Just exchange it before your time runs out.
Yeah, I guess that's what I'll do.

edit: you are right. I can see the difference. my colors are alot darker n vibrant. yours does looked kinda washed out or lighter. hmmmm....I wonder why yours is like that. So this is affecting some users then but not all as you can see from my screenshot. Maybe you should pm Gary Key, Asus representative and give him link to this thread. I'm sure he would take a screenshot with his also to compare.
it does look like yours is stuck in powersavings mode. Maybe you should gather the others you know with same issue and make this the official thread for it. So all of you can be centralized here n Gary can address it.
mine only look washed out when in eco mode, switching to balanced or performance mode turns them normal.

If there was a problem with the display would a screenshot actually capture that? I don't think it would. Like when I take pictures on my sgs2 the pics look very saturated due to the screen, but when I transfer to my computer, it doesn't represent that.
Not saying your screen isn't fine. I just don't know if a screenshot could show one way or the other.
Yeah you would need to take a picture of the screen with a camera to actually show the bad color saturation. But I think other people are not having this same problem as a few of us are. I think it can be fixed with software, but I don't know if I should wait or just try to exchange at gamestop today

well for one, that screenshot I took looks exactly like that color test looks on my screen.
2nd. my display of color test looks alot darker than his pic he took with camera. So i can tell either way there is an obvious difference. His looks like its in powersaving mode. mine looks like in normal mode. all my colors look right n very vibrant and colors look like they supposed to. not washed out like from his pic.
Plus from what you saying, taking a picture of screen with a camera will more than likely not truly represent the colors seen. it could easily distort or oversaturate or maybe even washed out. Taking a screenshot with Prime built in screenshot feature will show you a shot exactly how it appears on the display. not distorted or any unwanted fx added to it. So the screenshot I posted is exactly how the colors look on the Prime.

the pictures from screenshot display on other devices still looks diff. so to have a 100% fair comparison it must be done hands on or eyes on it physically. displaying the same picture
posting a screenshot doesn't help at all.. i can also take a screenshot and get the same colors you get on your shot, that doesn't represent the colors actually shown on the display though.
i'm already in the process of sending mine back, otherwise i'd make a couple more comparison shots showing single colors only. the colors are definitely not right, another person i asked noticed the same.

well I know my screen colors on my display don't look washed out like that. Still don't get how taking a pic with a camera, that will distort/alter image is better than a screenshot. too many variables that can affect the picture when taken with a cam or phone cam. The megapixels size, any default fx added, camera quality, size of lens..etc... no two cams will take exact same looking picture. There will be variances in color displays. I dunno..lol the screenshot I took, IMO, looks exactly like the color test looks when going to page OK web browser. Plus another clear indicator of power saving mode was how the icons look on homescreens. powersavings mode would have icons looking less detailed, washed out n almost cartoonist looking. Mines doesn't look like that. I was the 1st. one when prime first came out to point out the display color and contrast change when going into powersavings mode. I think I talked about it also in my "Performance modes of Prime/tegra3" thread. in my sig.
you all might be on the older firmware like Gary described before n y'all stuck in power savings mode. I have very good eyesight n my display looks great. if my display was washed out like those pics then I would notice it immediately.
take a screenshot of your homescreen icons n I can tell if it looks like in powersavings mode or not.
look at mines below n see how all the icons n everything looks crisp. nothing washed out or cartoonish looking. Screenshot looks like Exact replica of my display.
Do you notice a difference in screen when you flick between the power modes? Because I don't... My screen also washed out/yellow tint
Is it firmware fixable?

well for one, that screenshot I took looks exactly like that color test looks on my screen.
2nd. my display of color test looks alot darker than his pic he took with camera. So i can tell either way there is an obvious difference. His looks like its in powersaving mode. mine looks like in normal mode. all my colors look right n very vibrant and colors look like they supposed to. not washed out like from his pic.
Plus from what you saying, taking a picture of screen with a camera will more than likely not truly represent the colors seen. it could easily distort or oversaturate or maybe even washed out. Taking a screenshot with Prime built in screenshot feature will show you a shot exactly how it appears on the display. not distorted or any unwanted fx added to it. So the screenshot I posted is exactly how the colors look on the Prime.

What I am saying is that if you have 2 devices, 1 with "correct" colours and one with washed out colours, take the same screenshot of the same website, pic or whatever, If you were to view both of them on the same device they would look exactly the same. The data you are taking with a screenshot is the same with both devices (basically saying what colour each pixel should show). How your personal screen represents that data doesn't change anything. So a screenshot can't prove one way or another good screen colours.

I seem to get a very subtle change when I switch to power saver and then back. It's not nearly so great a difference as it was prior to .33, but I do believe it's there.
And if my colors are indeed washed out, I certainly haven't noticed. I'd love to see this problem side-by-side with a known working unit to see just how much the difference is. I'm not getting anything from the pics and screenshots in this thread.

I guess so then..lol. all I know is that that screenshot I posted looks like a carbon copy of my display. not enhanced or anything like.
Either way I know how the washed out power saving mode looks. It seemed to me like they changed it out from a later update in HC and ICS. zit isn't like before where as soon as you put it in powersavings mode the contrast n details would change. now it seems to do nothing. For me its more like its permanently in balanced or Normal mode colors. It looks great to me.
OK, someone experiencing the washed out colors, take a pic with your cam of your homescreen then have a screenshot of exact same screen next to it.
Plus a camera can't show good color quality when you taking a picture of a LCD or computer screen. That's what I'm not getting. Why use a cam that obviously distorts the real image of a digital display? Cam taking picture is converted to data. Screenshot is converted to data. only difference is with screen shot you don't have to worry about the various variables that would affect the final picture. you can take 2 camera and take a pic of the same thing and there would be slot of differences. Color, temperature, contrast, hue, brightness, etc.. Plus showing another device, a phone, for side by side comparison isn't a true test. phone display is different. resolution different, color, contrast. etc...
My main complaint with the screen is that last 2 out of 4 TFP's I had had washed out colours. Yes, there is a thread in regards to colours, but I want to take slightly different approach.
On Sensation, if you run command "dmesg" without brackets it brought load of info, including PANEL_ID_PYD.... Which gave you type of the screen. Since I had 50/50 good/bad screens, I wonder if we have different screens being shipped with TFP. Unfortunately, that command doesn't bring up anything like that, so question is, how to check screen manufacturer.
Now, I bet 100% that some of you have it and don't even know about it. My family thinks I'm mad, but being an amateur photographer made me see colours a bit more than your average person. So, even if you don't think your colours washed out, please check it and let me know your findings.

from the reports on this forum there definitely seems to be a lot of variation in the calibration of the tf201 screens that have been shipping. people who care about color and have gone through multiple units have observed that one is warm, another cool, another washed out... putting color tests up side-by-side against my HP ZR30w (S-IPS) and samsung GSII (super AMOLED plus), my tf201 is definitely a bit too warm and it doesn't have the best gamut compared to high end displays. but that's not really fair because both of these screens are more expensive and higher quality than what the tf201 is spec'd out to be. imo the tf201 screen is still very nice compared to other tablets out there so i'm fine with it.
Thanks for the input. I don't mind it to be on a warm side, but I like my red to be RED, not pale red. Same goes for blue. These seem to be most affected colours.
Anyone else?

The colors on my screen aren't even consistent lol
If I manually set my brightness, sometimes I'll unlock the screen to find deep, vibrant colors, and other times I'll unlock it to greens that I can barely see and reds that are nearly a shade of dark pink...
I personally believe that aside from actual individual defects of these screens, that ICS is at least partially to blame.
Anyone still on Honeycomb who can check this out? I swear I can't find a pattern to what causes them to look good or washed out, but I never know which I'll get. Reboot generally comes up to good colors (haven't noticed otherwise anyway)
I can tell you. Watch MAPS icon carefully, switch to battery mode, then back to normal or performance and watch the magic happen. Then lock and unlock screen to find normal-ish colours again.

But I never take it off the battery-saver. Ever. And my colors still get tweaked (although that explains lack of issue on boot up) sporadically. This is what I assumed it was at first, and may play a part, but isn't (in my case at least) the whole story...

battery saver mode definitely degrades display quality, wouldn't be surprised to find that it induces color shifts as well. run balanced mode for a while and see if you still have the problem.
Actually, in my case saver mode gives more accurate colours than two others. Did you do the test I mentioned in op ?

Lol, I ran that "test" just by looking at home screens, then inside the market the first day of owning. All you really need to look at is your market, then look at the green, orange, blue, and red rectangles for the different sections. My tablet is ICE compared to my HTC Vision. I mean, almost looks like different pallets entirely.

Yes, this is the exact problem I had. My colors were good until the .33 update. Now it is washed out. I returned it for another one and it is just as bad. I guess I got unlucky twice. I wonder if theres a firmware/software update for this issue. My HTC thunderbolt looks a lot better

This is why I think it is an issue of software more than anything. I do know that screens by default will be cooler or warmer than another; my identical LG LED monitors are just the slightest bit different. But the issue with washing out is something I did not notice in the few hours I was able to use my Prime and root it before it updated.
Yes, some will be slightly "defective," but I'm waiting for this next update and some homebrew'in ROM love after the unlocker. Then we'll truly see what's going on.
It's not as noticeable as it really is, dig?
I think it's clearest on magenta there, this is on Performance and SuperIPS.
The reason I'm doing it that way is that the picture is aweful without the SuperIPS on, when side-by-side to my LED screens.
Power saving + SuperIPS. More noticeable, but still doesn't look as bad as it does on the naked eye
Side-by-Side [Power saving | Performance]

Your one is good, very good. I'll post mine in the evening.
Now to determine wherever it is sw problem, we need to see if all of primes are the same, and if they are not, do panels differ or not. If panels are different, then possibly it is software. If panels are identical, then we have same sw, same panel, different colours = bad screen.

You cant just compare the colors on two different devices and say its the primes screen. There isnt a single display/graphics card on the market that displays colors correctly uncalibrated, regardless of how much you paid for it. With most displays the colors will be affected by the luminance levels. Most people adjust their displays for higher contrast and more saturation than what is actually true which can make other devices look pale or washed out. Im a professional photographer and know all to well that you cant use and uncalibrated monitor/grahics card combination for color adjustment in the photos. Ive seen many people over the years blame their cameras or printers for bad colors in photos when in reality it was the fact that an uncalibrated monitor was used in post processing. I use Xrite colormunki calibration tools on my PC and printer to make sure that what you see is what you get and its all true colors. This solution uses an optical measuring device and sends color offest values to the grahics card and print drivers. Any color variations are defnitely a matter of drivers to the display and unfortunately there are no adjustments available on android tablets although Spyder did release an app for Ipads.
I understand where you are coming from. It's not realistic to expect everyone to have calibrated screen. And yes, colours will vary between computer screens.
I had 4 primes, so I do have something to compare it to. I didn't notice anything like that with the first two, but it was obvious with last two.
Also, I compared it to all devices I have, and every device outperformed prime in regards to colour reproduction, especially red and blue.
Could you check yours with colormunki or against your calibrated screen please?
I really hope it's down to software, but I can't afford to gamble £500 on it.
I had some prints done professionally and compared them to my screen, so my screen is fairly close to real colours.

Never had this bluish tint on any phone before. Is there a setting for this? Im gonna wait for more replies to see if this is normal. I have 13 more days to return.
Mine has it but I don't find it to be extreme. I prefer the slight blue hue to some other devices that are slightly pink or yellow at an angle. I have to put my device at an angle I'd rarely (if ever) use to see the blue tint.

Actually is "normal".
All reviewers I read in my country (Italy) said something about blueshing whites with different angles, so I think that it's a common issue with the P-OLED technology ATM, so if it's a problem for you change phone and avoid the Pixel XL2 and the V30.

No, looking at your phone from an angle is not normal. Most people look at their phones head on.
Settings-Display-Screen Color. If it's on Normal you will see more blue hue. I changed mine to Photo and that reduced the blue significantly. There is a custom setting. Don't know if you tried this yet. If you did and still have an issue, then I don't know what to add...
Take Care!!

i guess u never had an amoled screen phone. galaxy s6 and s7 suffer from color shifting but samsung has better quality control over their screen since only a few devices has this. LG probably didnt care much about this issue and my guess is that most v30 have this problem. is lg first attempt on oled screen since the flex serious but they really need to work on their panel issue. dont bother exchanging.l since u probably going to get anothe device with same or even worse color shifting. if u cant live with it and want an lg phone, wait for lg g7 and wait for review to pops up.
this issue does not bother me and i already own a s8, s8 plus and note 8. v30 screen might not be good compare to those but to me it still a beautifull screen
on the side note. lg gave us 2 year warranty. maybe a new batch a few month ahead fix this issue and we can do a warranty replacement
This seems relatively widespread, although may be to differing extents, as there are reports of the same blue tint on angle for the pixel 2 xl which also have oled panels by lg
having the phone lying on a table makes me look at it at an angle all the time. this is an issue. Samsungs display are quite advanced over the LG displays it seems.
But I don't change the angle all the time while looking at the screen, so I don't notice it too much.
Also, whenever I don't have a uniform or white background, I hardly notice (although the tint is strong).
e.g. when holding looking from the bottom, which I do often (when it is laying in the table)
Any Ideas, if this will be fixed next year, or is this technology based and remains? (samsung has redish tint, e.g. IphoneX)
You can try these color settings. It seems to help lessen the blue tint. https://forum.xda-developers.com/lg-v30/how-to/v30-screen-colors-achieving-d65-white-t3695617

hardware limitation. Samsung's have it too just much less. i notice it sitting on a table also, so try to angle it right. aside from that it's a nice clean panel. it's 1 of only 2 complaints i have, this and no led. no big deal over here. nicer than my htc10 display, that's for sure. better phone, too.

Non-issue.
I look at my display straight on, when it's unlocked.
If I'm not actually holding my phone -- if it's on a table or on tilted Qi wireless charging pad -- then the display is LOCKED and the black & white "Always On Display" is showing me notifications. There's NO blue tint on AOD.
But if I'm holding my own phone and looking at it, reading emails, I couldn't care less about OTHER people not being able to read my screen due to some off-angle, slightly blueish tint. It's none of their business.
Maybe someone will yell at me, "Hey, tell LG to get rid of that off-angle blue tint so I can read YOUR emails better!"

Agreed. It can be pretty severe but doesn't affect me at all as there's no need (for me at least) to look at such a small, handheld device from an angle. Would be an issue if it was a TV obviously. I guess some people might disagree if they need to look at their screen from an angle often for whatever reason, but if that's the case they should definitely go with another model.
Don't call a bug/quality issue a feature... that is just too lame. Of course Samsung has the issue, it tints red, but at a way lower rate. IPS is greater in many ways. Of course not in rich blacks.
Does anybody know if there are any display revisions within the V30? Some reports about the pixel (TheVerge) say that newer phones may be less affected.
The blue tint bothers me, but I really like the phone. Just wish there was a litte less tint.
Anybody know if there are different display versions? qualityise?

So the Pixels are now equal to the V30? Because theirs was even bluer than the V30.
I don't see it because I don't look sideways at either of my LG V39/V30+. phone. My wife hasn't said a word about hers either.

take 5 pixel2xl and 5 v30, they are all different in screen quality... that is what bothers me.
maybe they come from several production batches, but technically they are the same.
does anybody know if there are any screen hw revisions on either pixel2xl or v30?
I know that different people have different opinion about quality. some use pc monitors with TN panels... not because they are so nice to look at, but because they are gamers and the panels switch fast.
oled is a promising technology, but LCD is way more mature... If you don't see the tint or if it does not bother you, that is ok for me. but I see it alot, and it bothers me. because I use several devices all day long; and if my personal device looks inferior/different, then I don't like that for the price paid...

Comparison between my old Xperia 1 II (how the screen should be) and my new Xperia 1 IV.
Is anyone having screen problems with their Xperia 1 IV like color banding and screen artifacts in dark areas of the screen?
I've tried everything to fix it like Factory reset and Software repair but nothing worked.
Nothing like that here. But looks more like some issue with status bar then the screen by your description.
If the screen is a bust, should be visible on lighter colours. If it is related just to dark colours than why is so perfect line just on status bar and nowhere else on the black screen.

Here's a better picture of what I mean, look at the artifacts around the moon on the Xperia 1 IV screen and there's nothing on my S22 Ultra screen, And I'm using the same JPEG picture on both devices, Photos and Videos look terrible.
And also the problem is the same described in this youtube video at 1:13
Hey,. I actually had the same issue. It appears to be related to the 120hz refresh rate, and it is really noticable when the display is dim. I think I found a way to fix it, as the issue is now gone on my screen after messing around to display settings.
1. Set the image settings to standard with auto creator mode on.
2. Set the white balance to custom, and move the slider to just before 9000 kelvin. This will make your screen a bit cool, but it's not too bad.
Let me know if that works for you. It did for me.

How I do that?
Just contact the Sony support by going to the Sony website. I've been playing around more, and I have a feeling that it has something to do with the auto-creator mode. I've turned that service off. See if it makes a difference for you.

I'd return it if you are still within the return period...I returned a faulty I IV, battery stopped charging after a week or so. Don't get involved with their pathetic Sony Support, they will try and fob you off with any old ****..."its a feature blah blah blah"...

Yeah I know but I'll wait for a software update nonetheless maybe it'll fix my problem, If not I'll personally go to Japan to fix it there at their own expense.
I haven't had time to take photos but I can confirm this issue, and I'm convinced every xperia 1 iv has this exact problem. The reason you normally don't notice it, is the factory white balance is strongly tinted towards green, which hides the fact that the shadows are also tinted green. As soon as you adjust the white balance towards any other colour (including actual D65 white) you'll notice only the midtones and highlights get adjusted, while the shadows stay green. Just like everyone else I hope a firmware update could fix it but realistically I don't think it will, and neither do I expect Sony to fix it in hardware. Maybe if it becomes a big enough PR issue for them.

It's a hardware problem, all mk IIIs had it too. It's not something you can patch. I had hoped Sony would change their screen supplier after how bad the III was, but alas.

I think it's a software problem because when I switch the brightness more than 90 percent and play HDR videos on youtube everything looks fine, But when viewing regular photos and videos below 90 percent brightness everything looks low quality.
Interesting, I read around a bit on the issue of the 1 III, and apparently all phones that use Samsung OLED screens have this issue. I can confirm it disappears at 90+ brightness, and OLED Saver (no longer available on Google Play but you can still get it from apk mirror sites) works to fix the issue. However of course OLED Saver has its own issues like dark screenshots and colour banding.
It sounds like this should be fixable with root, just need something to adjust the qualcomm display LUT (like Night Light) which should fix both the dark screenshots issue (display LUT does not show up in screenshots) as well as the banding issue (the LUT should work in 10 bit space as the display is 10 bit native).

I don't know but it appears there is an upcoming update version 64.0.F.9.8 for the Xperia 1 IV, I think we'll have to wait if it fixes anything, And also Sony replied to my problem by email with apparent nonsense.

I checked in with two friends of mine who both have Samsung phones with OLED screens -- presumably Samsung is vertically integrated enough that it uses its own displays in its own phones -- and neither of them had the issue. In fact, their near-black performance and lack of banding put my Xperia to shame. If the underlying hardware is the same or similar, then we should really hold Sony accountable for this. It's worrisome that Xperia 1 III owners have been dealing with and complaining about this issue for a year now and nothing has happened though.
Edit: It seems like the October 2021 update (62.0.A.3.131) fixed the issue for the 1 III. This makes it even more puzzling that the issue has returned at all on the 1 IV, supposedly Sony already knows how to fix it at this point?
Which region are you guys in? I'm in the UK and I never had this issue on my 1III or my 1IV, I do root my phone's before I even mess with them like so no idea if that's why I don't get it
I'm in the Netherlands and supposedly running the generic EU firmware.
Same problem here.
Every update so far did not fix it.
Some specs and what I have tried:
- Android 12, Update 64.0.A.5.71
- Software repair and factory reset did not help.
- XQ-CT54 (EU, Germany)
- White balance does not fix it
- Creator/Vivid mode does not fix it
- 120/60 Hz does not fix it
- Brightness > 90% is good, and < 90% is bad on SDR
- Brightness < 50% is REALLY bad on HDR
The problem:
What I have noticed is that black gets "crushed". Banding or distortion, call it whatever you want. Near black greys turn either black or greenish grey. Looks like a green tint, especially noticable in HDR. Otherwise it is some very slight greenish tint. The green tint gets reduced minimally when using 60 Hz instead of 120 Hz. Conditions are the brightness is below 90% in SDR and below ~50% in HDR.
- When booting the device there is green artifacts around the logo.
See my pictures and the youtube video here showing the "pop" around 90% brightness:
Also check the artifacts in the MrMobile video around 6 seconds (or screenshot below):
This is exactly what the artifacts look like.
Reddit post about this problem:

I have sent all evidence to Sony support and they told me yesterday to send it in to checkup and repair.
Tomorrow I will check if my friends Xperia 1 IV has the same issue.
But I am thinking this can be fixed with a software update, I mean ... It looks perfect on certain brightness levels.
UPDATE:
So I checked with my friends Xperia 1 IV and he has the same black clipping problem as I have. BUT he has no green tint. Same settings on both devices and his was looking so much more natural.
Also I found out, that my 120Hz mode makes it even greener.
So I am thinking the black clipping is a software calbration bug of the display, because it does not occur on brightness above 90%. Also the display itself seems calibrated wrong (software fix possible?) or it is bad batch by factory with the green tint.
I will contact Sony again and their repair service and see what can be done about this. This is so frustrating.
