I just received my Mate 20 Pro today from Carphone Warehouse.
What can I say.
The colours are very washed out and "Cold". I know you can adjust the colour temperature in the settings, however even the warmest colours doesn't match the colours of my S8 Plus.
I'm not too sure what to say but I'm a bit disappointed that the colour options are so limited.
You compare this screen to the screen of the S8 Plus and you'll understand exactly what I mean.
A bit disappointed to be honest.

Just dont compare it... use it for 3 days without comparing and you will adjust... i had the same with my old nexus 6p and i realised the screen was worn out. „White“ looked like bluelightfilter on.... i had never noticed before.... its all a matter of adjustment s8 is not the holy grail of screens especially when over a year old... oled screens contain organic material and it ages/wears out

Amazing, go and watch some HDR content on youtube, you will see the screen come to life! I think they were conservative with the display profile, not too much saturation until you fire up HDR content.

I think I'm having problems with my display.

Im having some darker bars across the screen (horizontal /portrait) top is brighter than button.
It is visible in a dark room/at night only with a dark grey wallpaper.
I compared S9 plus with and on s9 plus the grey wallpaper looks even.
The mate 20 pro screen is a touch dimmer than s9 plus.
The screen otherwise looks great

It seems most are suffering with this. Unless it's really severe I'm not sure Its worth getting in a panic over. Only seen in a dark room, lowest brightness on a grey background. So not something that's gonna crop up often imo

To be honest, there's no way i will ever use the screen so dim, its barely visible in dark. My only fear is not to get worse after a while, but again there is a warranty.
How can i upload a photo?

Just for the record, I used Display Calibration by Apps Ladder app and I think it improved the overall Mate 20 Pro experience.

Hello, Please test for black crush or shadow clipping. Thank you

Having the same issue with my mate 20 pro. Came from an S8 plus and I'm highly dissapointed about the screen, colors too white and washed out. Anybody else know's how to fix this? Is it a real problem or just a matter of personal preference?

Hi, has anyone noticed that the half bottom of the mate 20 display has yellow tint compared to the half top? A Huawei warranty agent had already checked my mate 20. And he said that i could exchange for a new one if it does not have the same problem as my old mate 20 had. I have watched some Youtube mate 20 unboxing clips and I thought some of them had that yellow tint issue too. My two previous LCD phones have light bleeding but not the yellow tint like this. How about yours? I'm a little worried right now!

In the first picture the defect is exagerated , the second one is a iphone XR wich seems to have the same problem and the third is the mate 20 original picture.

I think huawei lcd screen technology is bad, the new exchange phone of me still has that yellow tint just not that much like before. Do you know why is that happen?

Yes, same goes to me. I visit service center once and talk with the technician. Seem the problem occur is quite rare in my country. (malaysia). But, he ask me to keep update if the yellow tint become worst.

I have the same a slight warm white on the bottom, and a slight bleed, sometimes is difficult to see, it depends of light and brightness conditions.
So I was thinking in exchange it, so what is the odds of getting one better?

Why didn't you go for replacement, if is uncommon the odds would be great to get one perfect.

That is what im thinking but currently they still fixing mate 20 pro bleeding issue. So, i don't think its a good time to replace due to waiting period will be longer than it should. ???

apparently the phone panel has a strong yellowish tint and to remedy that choose vivid cool .. this will make whites whiter not yellowish .. with colors set to vivid cool i still do notice the yellow tint in the lower screen and bleeding light but they are very minimal and i am called a pixel peeper .. at least this will make whites whiter not yellowish
but the other problem is the over-saturated red color .. not only that when you tilt the screen and videos is full screen contrast is enhanced and colors becomes over-saturated automatically and this makes a lot of videos looks overly saturated in landscape mode

I haven't noticed that. Seems perfect to me.

Little update, I'm in a second unity, and the screen is more uniform, but white is more a warm them the first, even trying to compensate with vivid setting and adding more blue, the color temperature is diferent.
Regarding the backlight bleeding is less visible also than the first unity.
So I think is kind of lottery having a perfect screen.

Minimum brightness

You don't want to give your significant other yet another reason to yell at you while you're reading XDA in bed. Rate this thread to express what you think of the ASUS ROG Phone II's display minimum dimness. A higher rating indicates that the display can get extremely dim, ideal for reading in very dark environments.

I am quite concerned about some of the comments I saw on JD.com . People say the screen is yellowish, uneven coloring and grainy which gets even worse when the brightness is low. Can anyone confirm this here?

In terms of brightness I would say it's average at best. The screen is very dim my current brightness slider is set at 80% and that is just to navigate conformabley. But I would recommend a 85 to 90% settings.
The screen isn't yellowish quite the opposite actually in comparison with my 1st generation ROG, colors are even I would say and no grain.

Hopefully it's just a software issue and will be resolved shortly. Hell, it couldn't be worse than the OP6T. And the ROG2 has around 200 nits more than the 6T. That fukn thing, you can't see **** on if its bright out. Overall, I would think the extra 2,000 mah would compensate for the higher brightness til its fixed.

But even if the brightness slider is set to 100% shouldn't consume much more battery if the screen is still dim...right?
By the way, can anyone let me know how bright is it compared to Razer Phone 1?

With 6000mah you have nothing to worry about. Reduce the refresh rate to 60 and you will get time over or equal to 10 hours standby time.
Regarding the razor phone I would think it would be much brighter because it's an LCD panel. But I am not definitive.

just got my tencent version today. the screen max and min brightness is slightly higher than my oneplus 5. uneven colour/graininess requires you to squint with your face almost stuck to the screen so its really a nonissue. white balance is pretty on point and actually a little on the cool side tho whites are almost perfect white

The screen is excellent in my opinion, and while the maximum brightness isn't the brightest out there, it's perfectly adequate even in direct sunlight.

As far as low brightness goes, I felt like the lowest brightness was still a little too bright next to my wife in bed so I installed low brightness pro. If anyone else feels they want to go lower..

Got the phone. Definitely too bright at lowest so either use an app to add dark overlay to dim or wait for a software update I guess

Yes it does have a red tint on dark grey colors. Visible everywhere in apps using dark theme based on grey like google apps dark mode, the rog ui itself and any dark grey on screen.
Effect is more pronounced while using 120hz. And less on other modes.

Same here, got the tencent version. Lets hope its just a software issue that future update can fix it. Im coming from s9 plus so its hard to compare the beauty of the screen.

Minimum brightness is way too high. Reference compared to nexus 5x and galaxy s7 on lowest setting. It's blinding

Rog 2 is brighter than the sun
I have a great appreciate of the capabilities of this phone, no matter what you might hear this phone has superb color rendering and there is no beating the refresh rate. When it comes to comparing how it delivers in color saturation compared to its competition all you are doing is splitting hairs... But as for its minimum brightness, well you cannot appreciate how truly bright the panel is until you are trying to write a blog post when the lights are off and your partner is asleep next to you.
With the slider all the way down its impossible to look at the screen without squinting real hard because those whites burn through your retinas and imprint on your soul. Do you like watching Netflix on your phone in bed? Not on this phone you won't. Want to read that last Facebook alert you just got after you turned the lights out? Absolutely you can do it... If you like staring at the sun that is. I sincerely hope Asus can do some sort of work around and deliver less power to the display in total darkness because light induced migrains are not fun.
Otherwise pretty good phone.

Display issues

Hello guys, suddenly I'm having display issues on my k20. I've attached a link to the video, when i pull down the notification bar, look how the blacks are loading a bit late. When i turn off dark mode, i see no issues like this, it's just the beautiful display again. Even i had same issues with my dark wallpaper. Please check, if you've same issues. I'm really concerned about it. Also, this maybe screen flickering but when i increased brightness, the issue didn't disappear, it was still persistent but at lower levels.

That's normal behavior for amoled displays.

1st: If this is the display problem, how can you expect we can see this on a screen capture??
2nd (probably because of the 1st): I can't see anything wrong.
3rd: I have no display issues at all.

Can't you see that voilet-ish colour instead of black when I'm swiftly moving the notification bar? It's clearly visible in video, you might want to check again.

Nope, watched it at least 5 times, on my PC and my 9T. Can't see anything peculiar.

I can not see anything wrong or violet at all. Am playing this on my computer at 1080 resolution and 0.25 playback speed and there is nothing to see.
If your screen is faulty, we are not able to see it on video you have shared with us of course

DAMN IT! Even i see nothing from my laptop
I think I'm having screen issues, only when its dark mode, else the screen is working absolutely fine!
I need to get to the service center ASAP! :crying:
Edit: Guys can you try doing the same and look if the issue is persistent in your screen too?! It would really be helpful for me.

It's normal for OLED panels, some are better, some worse. My phone has it too. No need to go to the service center.

I too have it brother. Dark mode has it normal mode doesn't. It can also be noticed if you open youtube and scroll back and forth quickly. The blacks seem to be spilling or streching. I saw that on your video and I don't know if it is normal or not but i too have that and wanted to ask someone about that.

People are claiming this to be normal, but after searching a lot i got to know these kind of issues come after 1-2years, not in a week or month. So I'm trying my best to replace my device or get the screen changed. I don't understand why Xiaomi is keeping the colours to pure blacks when they know their displays are facing smearing issues. I hope someone just changes that pure black colour to very dark grey colour, system widely. Some developer tested(on OP7 pro) the battery consumption difference with pure black and dark grey and it turned out that, dark grey consumes only 0.067% more power than dark inky blacks. I'm humbly requesting developers to change the colour, or at least have an option for the same.

My display when there is low light, the brightness is set to low and the image I see on the display is darkish I can see a vertical line at the left side of the display, is this normal or should I return It?

It's normal for Amoled screens (from first day of use). Just search for Amoled black smearing and you'll find a lot of videos and articles. S10 has it, iPhones have it too.

I have faint vertical lines on the right of the display when the brightness is low which is how I normally use it. I also have black smearing on pitch black to dark color transition. I think thats normal, it doesn't really bother me all that much.

The best way to reproduce this issue is turn off brightness to minimum and turn on reading mode to max. Then you'll see delay of displaying some colors (mostly gray)

My k20 has this issue and it's annoying that after paying for a flagship killer, we just got a cheap display which is not just low in quality but has these issue in dark mode which i think most of us use. Interestingly when i record this from screen recorder,it doesn't show up much but the same can be seen visually. So, this is definitely an issue that redmi is trying to let go.

As you "record from screen recorder" you do not record from the screen as you may like to think. You capture the video signal BEFORE it gets to the screen. So any imperfections caused by the amoled screen do not show up on a screen capture.
Anyway, this is a normal weakness with all amoled screens that I have seen.

It is soooo annoying when in dark mode at low brightness, I feel like I couldn't stand it anymore. The worst experience of display usage ever.
Maybe with DC dimming update that might happen someday, the issue won't be as intrusive and pronounce as it is right now. But whenn???
UPDATE:
So I found a workaround for this issue with an app. It's called Screen Balance. Basically it adds a filter overlay on your screen (ineffective on notification panel, because android restriction). Set it to either flourescent or flourescent (warm) at 15% strength minimum, and both brightness and contrast at 100%. You won't see perfect black anymore, but very close to that and no smearing effects visible unless you're really trying to.

I've bought Mi 9T Pro and have the same issue (also see it in your video). Did you fixed that?

I bought the phone a few days ago and it had awful yellow/orange tint on white color compared to my Redmi Note 4 Global, and it was worse with lower brightness... therefore entire color palette was off, tried to make it to be more blue in Android display color settings but no success, actually returned the phone, not this for such money. (Europe market)

I don't know why but I can't look at the screen for too long, I get a terrible headache. Also the white is not white but red. I wonder if xiaomi will acknowledge the problem and fix it via warranty

I don't consider this to be normal though ...

That's exactly how mine looked as well.
Good thing I was not alone with this...

I noticed it changed at night time. I disabled reading mode but it still changed to this colour. Same with when you watching HDR quality video in youtube.

For me it's has the same tint on all possible color settings when the brightness is low, which is driving me nuts. Too bad since it was a decent phone for the money. I cannot return it though.

I have a reddish tint on white when the color scheme is set to original.
On Auto, white is pretty much ok.

This is happening to me aswell. European version having a yellowish/red tinted screen, which doesn't get fixed with the adb commands linked by getaceres, and I also get heavy eye strain and I even feel dizzy after a while staring to the screen. I'm in the process to try to get a refund

Pulse width modulation vs current modulation. The pulse width modulation is irritating to some especially in low light. Some devices allow you to choose between the two.
This seems to have become as issue with the variable frequency displays.
What is 'DC dimming,' and why are phone screens getting it?
www.androidpolice.com

That's only available for OLED screens. My problem is not PWM, it's just the red tint. Compare it with another phone on a white background and you can see the difference right away
