Hi,
Is this normal or should I do a RMA with Amazon UK? Any of your NST has this problem?

I think both mode comes with yellow tint of cos, sRGB mode is more yellowish and the screen is definitely not as bright as Nexus 7 2012.
Pls comment. Thanks.
Is auto brightness on or off on both devices? I find brightness can affect color quality sometimes.
Is PRISM Mode on or off on the shield? I have turned this off in the hidden NVIDIA power menu (see other posts about this) because it was causing some color issues for me.

both screen are at its max brightness. Let me take a look at the PRISM mode.

For the record, with Native color mode, I noticed a blueish tinge to the screen. I selected sRGB to correct this and whites look white like they should.

slightly brighter a bit but the brightness still loses out to Nexus 7 2012. Using Native mode, the colour is still slightly yellowish/ greenish compared to Nexus 7.

sRGB mode is making the screen looks even more yellowish compared to my OPO, N7 and even my Macbook. Should I RMA it or is that any tools that can calibrate the colour?
Turn it to native and it should be less warm. The shield has a warm screen compared to other devices. Warm screens reduce eye strain and is better for viewing at night and does not affect your melatonin levels as much as cooler screens when reading before bed.
Suddenly my Nexus 7 looked exactly like a Galaxy S2. Don't worry, you aren't the only one to notice this, but even my keen eyes weren't bothered by it when it was alone. And I'm a big Samsung fan, so that's saying a lot.
So, my screen isn't too warm, but the top 1,5 cm have a yellow shadow. I think this isn't normal. I think, I have to make an rma.

Mango comes with default red. Anyone can verify??
Hmm, what a strange assumption?!.. If it was a black on black scheme, I can agree
Black on Black uses more power on "regular" LCD Displays. AFAIK, only AMOLED screens use less power when displaying a black screen compared to white.
red is a low intensity colour right?
used in military for night operations..
I assume the change to red as default color scheme comes from the new, square windows phone logo. They changed that from a green circle to a red square.

Another strange assumption Why do you think so?!.. Do you have an idea how LCD display works?
yes, I know how LCD Displays work. The ammount of power it takes more to show a black image i just so tiny, that it doesn't really matter.

I don't understand what you are trying to say but black pixels does not required power at all So, "black-on-black" is a most "energy-saving theme" unless it's just useless
on regular LCD displays they actually do, as pixels are translucent by default. It requires energy to "shut them" in order to display black.

That’s right - the EL light in the back is one sheet and it is always on (when powered up). Think of the pixels as shutters letting the light through-
I cannot imagine that one color scheme vs. another could make a measurable difference.
Guys, LCD uses a few slightly different technologies... Are you talking about old STN (Super Twisted Nematic) implementation? Forget about it! Try to google about TFD/TFT...
HTC HD7 use a twisted nematic display
In Malaysia, maxis gave out wp7 with default green color as its their corporate color. Celcom gave out w default blue theme.. I guess it's d operator thing..

Anybody else have the colors look a little washed out? I tried vivid and standard colors, but barely see a difference between the two. Maybe my S5 has just spoiled me.

The OPO does not use a Super AMOLED device so colors seem different, blacks are more grays. You can adjust it accordingly by using the custom presetting
Try http://forum.xda-developers.com/showpost.php?p=54321008&postcount=6
Adjust the settings around till you get it the way you want it.
The S5 is oversaturated, that's probably why this display seems washed out to you, it's a more natural colour balance.

I had the worst problem coming from a note 2 to a nexus 5. I put the nexus and the opo next to each other tonight and the displays look the same. Is just how a IPS display is.

Try these settings. Looks pretty close to my GS5.

When I have my brightness maxed out and the option to increase brightness in sunlight turned on I see this as well.
It's because most displays these days exceed the sRGB color space, and Android doesn't use color spaces, so colors are generally mapped to the full gamut of the phones' displays instead of trying to match sRGB. The OPO's color is actually VERY accurate compared to most phones out there (a major reason why I got it vs the Sony Z3). Just needs to warm up the white balance a bit.

What ROM are you using ? It was removed with 44S update long time ago
I got the phone 2 days ago and today I noticed a rather peculiar issue I don't seem to have noticed yesterday. I was browsing Instagram and there was this image that consisted of a lot of shadows and dark areas, as I scrolled lower the next image was much lighter and bright with almost no shadows and as I was seeing the image, the phone suddenly brightened up the shadows and the colours changed a little. I was surprised and I tested this in other apps such as reddit and the issue persists. If there is a lot of dark content on the screen, the shadows will be pitch black but as soon as the content gets bright, the shadows will get muddy and will behave like a LCD display. I even tried screen recording this but in the clip it shows everything is normal. This is annoying the hell out of me. Please help me.
What are your display settings? I'm pretty sure by default it automatically switches the resolution between 1440 and 1080.
Might be the oneplus video enhancer at work. Try toggling it off
I also noticed, it is due to the 90 hz, try to replicate your steps to 60hz, in my case it does not happen. I noticed it in the camera when making a dark photo at the time of opening it, it looked perfect to the delay of 2/3 seconds, it was horrible to see, the whole image turned blue and the black step to lcd (bluish gray very Dark). When using the camera or videos is reduced to 60hz in gallery up to 90hz

The display tapers down to 60hz in camera app, on call and while watching videos.
Change your settings.

Does it happen in bright areas? I've noticed when high brightness mode kicks in, blacks turn to muddy greys and when I go into a dark room, it normalizes.
Same issue with me. Funny, I couldn't find anything about this on the internet anywhere till today and came here to make a post about it. It's really annoying when I'm outside because the brightness automatically turns blacks to grey. Changing the brightness manually instantly fixes it though.
I think it might be a feature called adaptive screen or something? I don't have the device but I remember OnePlus mentioned something about optimizing the image displayed on the screen. Try to look if there's a setting about adaptive screen or brightnes
Is "Video enhancer" in Settings > Display enabled?
That will cause your display to shift between regular mode and "HDR" mode if video content is detected
Hi All
I have a vertical line on the middle of the screen in poco F2 pro MIUI 12, 8/256, this line appears in grey color when no or low light in the room when I run tester there is nothing in other colors put when on grey and dark grey it's appears if any one can tell me that is defect screen or what and if there is any solution. I'll attach a photo from another phone to explain.

Can't see the picture but I might know what you talking about.
My F2 has also vertical "spots" in low light/dark conditions when there also dark content displayed on the screen.
I think it is normal for OLED Screens, although I must say it is quite visible on the Poco f2.

Yes it appears in dark condition specialy on grey, dark grey color and a lot of apps using it in dark mode so it's normal no need to change the phone

Yes exactly. I must admit it is quite irritating seeing those at first; these "shadow lines" are especially more prominent when the DC dimming feature is activated.
I had those on every phone with OLED Screens (Galaxy S, S2, S3 etc. you name it) and also on the OnePlus 6.
I assume OLED Screens are not perfectly balanced out regarding their illumination strength or there are slight impurities/imperfections in the panel, since these are organic light emitting diodes. But I don't really know why these lines appear especially in low light conditions.
Other than that it does not bug me much (anymore) since in most use cases the lines/shadows are not visible.
It's my first contact with an oled panel from close view and personal usage. I noticed that the display acts like and LCD which is backlit even if there is a black image. Is the same supposed to happen to AMOLED? I thought the pixels would light themselves and if there is a black image, the screen should look the same like when its turned off - and it doesnt act like that, there is a dim light that's showing up when the screen is on and displaying a black image. Is it normal? Is the screen replaced with an LCD? ( i bought the phone used )
THanks!!
Easy test for an LCD, view through polarized glasses and rotate.
LCDs have a polarization filter so a second polarized lense with block the polarized light at some point in it's rotation axis.
Sadly i dont have a pair
I tried to take some samples of the pixels with another phone, here are the results:

Is it possible to say from these pictures that the display on the mi mix isnt RGB Stripe?
Like, maybe im considering it wrong, but i thought viewing from this angle an AMOLED panel with a black image should be the same like the second image when its off:
The contrast ratio of Amoled vs LCD is exponentially greater.
Searched through some logs and apps and found out its a samsung ea8076 - same display which is on the K20 Pro/mi 9t pro. Everywhere i searched i've found only amoled, i also looked up on the internet and there are available TFT replacements for the mix 3, i think it's amoled but it's very unusual - if i put a true amoled black image on the screen and increase the brightness, the screen gets brighter, even if there's nothing else than black pixels. Also, the maximum brightness is slightly lower than the one of my older phone ( RN3 Pro). I don't know what to believe at this moment.
Indeed it's changed, it's lcd, checked it under a microscope
to add on this, an easier test may be to check if a black background/image results in no light coming from screen (easier to see in the dark). LCD displays emit light (the backlight is still on) even for black images, oled do not

The easiest foolproof way is view with polarized sunglasses and rotate.
LCDs show their stripes...
