Clarity/resolution

The LG V20 has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!

i hate the image retention, my sony z3c, samsung note 4/edge not having the same issue.

Ghosting
?
It's past 1 year mark.
The screen ghosting issue is so prominent that it's annoying.
This is well known in the.forum's but it's not something that lg is talking about.
I'm going to have to find out if there is a recall or can get this fixed.
Truly disappointed.

I think Lg v20 display has a Good Pixel per inch ratio so that We can't see any dot with naked eye but thw color production is Soo Bad .....
I mean if we compare with Samsun display... They Are far better then This

The color reproduction on the LG panels is actually *really* good. Samsung cranks the vibrancy and saturation up on their displays because it is pleasing to most people's eyes. If anything, Samsungs color reproduction is vastly inferior with default settings. Both class of panels can be calibrated to be more correct though.
The other thing is that LGs colors are "cooler" and Samsung *always* biases towards warmer displays.

As we all knows people want Color vibrancy which Samsung is delivering actually.
I've tried to calibrate my display many time but even LG's display can't compete with Samsung's 2013 flagships display.

In what ways? And don't forget you are comparing an IPS-LCD to SAMOLED+ which will have vastly better blacks. LCDs can't yet compete on the contrast of an OLED.
I don't care what people want. They jump from one has to another and sacrifice utility for form at the drop of a hat.
I'll keep my color correct LCD that won't suffer from actual burn in
(My retention is all but nonexistent and that isn't permanent regardless)

Whatever it is.... There is no comparison between Ips LCD and SuperAmoled display .
By the way your retention problem can simply be fixed if you're rooted

You can try using the built-in Comfort View to make the display warmer. I set mine to high and it looks really close to my Galaxy Note 4, using the Basic display color option.

Huawei P20 pro Secondary rate amoled screen??!!

https://youtu.be/XIMLoLxmTDw
Hello everyone.. I'm sorry for bad English but try to understand it's important..
I think that Huawei cheated us with p20 pro..
We paid 890 euros for one of the best mobiles in the market and Huawei used second rate display of amoled.. And please tell me did you paid 890 euros for second rate display? I don't think so..
So follow the instructions and you will see what I mean.
Go on a completely dark room, without light at all..
Use brightness 100%
Click the video and turn your phone to watch it on full screen..
W8 for the a little bit and you will see white colours coming out from your screen and tell me..
Is that normal for amoled panel?
No its not.. Black should be completely black...
I took my phone to Huawei fix center and they refuse to see.. They don't recognize it as problem and they refuse to give me my money back..
What do you say?? Check the same with s9 and s9+.
P20 pro user.

no such problem on my device.

Also, why on earth are you paying €890 if you just received it? They're available for at or below €700 now.

I can see what you mean. I can see it even on low brightness. I have never done this test before, so cannot comment on other oleds I've owned.
Could it be compression? I say this because after seeing the effect in this video. I tested others, and i found that the severity of the effect is lesser. Also the uniformity changed between videos, whilst staying consistant to each.
Your video was much more pronounced than some others, this makes believe that there is something else in the works.
I know when i use a pure black wallpaper, the screen is perfect black. Also im pretty sure the AOD has pure blacks too

Pixel 4XL screen hue

Is it just me or the pixel 4XL screen has a bit of greenish-yellowish tint to it with Ambient EQ off? I'm kind of nit-picky so it's been bugging me lately.

It's a consequence of having 90hz at a lower brightness. Unless it's like that even at a higher brightness level?

Yup. I don't know why it's the 90hz cause never had this problem with my 7 pro.
I do find it is calibrated to green even in normal conditions

I've seen 7t but when you look a lot them are not the same and they look more like hardware issues.
I've had the 7 pro since launch and have had the community app, XDA and Reddit which I look at regularly and I've never come across a thread about a green tint because of 90hz

At 100% brightness it looks fine, But if I dim it to 75% or lower, there's a little bit of green tint when you look at it on a white background.

Can you disable 90hz on the oneplus devices? If you can then maybe it just never occurred to them to try to disable 90hz and see if the issue still persists. It certainly didn't dawn on me until I saw someone else having the issue and they reported disabling 90hz solved the problem.

I tried disabling 90Hz. It does not correct the issue of the green hue. It is not as bad, but it is still there. What disabling 90Hz eliminates (mostly) is the red-shift that occasionally occurs.

It's doing my head in now. My screen has a green hue, really bad on Grey's, worse the dimmer it is. I can turn my screen off and on and instead of a green hue it's purple and super contrasty instead. Going to try a replacement but I'm not expecting it to be much difference as seeing same problems from other users.
The black crush in lower brightness seems to be worse than the op 7 pro too

Don't waste your time with a replacement i did and it's the same, Google have calibrated it like this deliberately do a search on Google. Will wait for the 5 unless they've sold even less pixels this year than last year in which case we may not a see a pixel again while that current development team is in place.

Did you also turn smooth display off as well? Since as of the Nov update it kicks into 90hz at lower brightness levels now.

Pixel 4xl has very warm display. Staying next to my note 9 looks bad. Basically no whites unless 90 plus brightness.

Yes, I did. There would not be much point in doing half a test. I’m very thorough with stuff

Hi guys I have a pixel 4 whose display shows some green spots while displaying blacks. Do you think it's burn in or it rather be the green tint that everybody talks about? Thank you very much, I don't know if I have to do a replacement or not ?
ps. if you zoom in the right corner you can see these green spots

Looks like you have some stuck pixels there in this case the green sub pixel is stuck. Could try to run a stuck pixel fixer and let it run for awhile. But honestly ,it looks like you have so many that a miracle would be required. I would just contact support and have them RMA.

Low brightness - Screen Gamma/Calibration Performance

Does anyone else feel like there's a haze/fog over the screen when the brightness is around 20% or lower?
This seems to be more noticeable on grey backgrounds. White and pure black seem perfectly fine to the eye
It's hard to try and explain?
Could it be the same issue that*plagued the 4 when it originally came out. Gamma/software calibration*needed*possibly?
It seems fairly uniform too, which makes me think gamma issue rather than panel/HW issue?
Has anyone else noticed the same?

yes, i see the same!

Yeah, we discussed a similar behavior in this thread: https://forum.xda-developers.com/pixel-5/help/colours-bit-off-everything-bit-beige-t4179867
For me I do see this "fog" brownish tint in every brightness situation....

Not the same thing. You're on about color profiles in that thread. This is more like a contrast issue at lower brightness levels

Well... than i have both... there’s fog with loss of contrast and there is a „warm“ color calibration.
My P3 shows black areas where the P5 is grey. Plus, white is minimal brownish so i loose contrast.

I come from a Pixel 2 XL with the black crush. In terms of contrast at low brightness levels, the Pixel 5 is far superior.

Undecided whether to keep it or not.
Grey's look really weird compared to my S10e. Nice and dark on the S10 and really light/pale on the Pixel?
Here's a capture of screen uniformity too

AMOLED SCREEN

For the last 2 weeks i have identified an issue with its amoled screen. Under low light condition, with brightness level at its minimum, and with dark gray color as background (e.g. Dark mode in facebook), I noticed some lines of black and white which irritates my usage. I compared this with my mate 20 pro and I have not seen any of it. Iv tried to look about this in the internet but Im not sure. There are articles that say its banding, some say glue gate issue. Any thoughts?

I have the same issue!

I just spoke to Huawei Support here in Sweden.
They hadnt heard about this problem yet but they promised to check it up and get back to me.
I also informed him about my camera problem which is that pictures taken in normal cam mode ends up brighter and HDR like. This is not a problem on my mate 9 and mate 20.
Only way of getting pictures right is to switch to pro mode or change the filter....

Will go to service center tomorrow

But it would be nice knowing what kind of display they will replace with... Hopefully Samsungs or LG's.

Last night I discovered another screen/image issue...
I have a photo of my son as wallpaper. When I lowered the brightness to minimum (in a dark room), the photo looked like a 8-bit coloured photo from the 80's... Low colours, high contrast and looked like a sketch!!!!

Yes, it looks like hell and when you close it completely too ...
Why would you keep the screen with brightness to a minimum ??
Almost nothing can be seen ...

Just wonder how to explain properly for Huawei support here in Sweden in order for a replacement. They still havent got back to me yet......

Any updats about the screen issue, Zaxarive?
Huawei support, Sweden just called me.
1. They will escalate the issue with the camere higher up and get back to me.
But I guess the issue with "brighten up"/processed images from "normal" camera mode is caused by Huawei's new feautre "Ultra vision/Cine"... Never the less, it would be nice beingbable to turn it off when needed. I mean the whole thing just basiclly feels like a "HDR function", something that on iPhones have been a feautre the past 10 years. Apple lets you turn it off/on...
2. Most likely our problem with our displays in low brightness comes from having a OLED instead of a Super AMOLED... It just works in another way... Pity but the truth..! OLED has a much better blackness BUT with the costs of much harder to get a "sharp bright" image i low brightness mode....
Ill let you know when Huawei Support has got back to me.

Few months after any update?
