warm display? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Anybody else feeling that the diaplay on this device is slightly warm? Or have yellowish panel?
Any workaround or i have to replace the device?

Very warm imo.
I changed the ROM and playing with screen color settings, I could get a white white.

Why not go into display settings first and try to calibrate it to your liking.

They are talking about panel temperature not colors

oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy
My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

ok thanks, it's just reassuring to know that its not only my n1 experiencing this
Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

Galaxy S Sreens not same

Hi
I have 2 Galaxy s here so i compared the Screens of them. I set on both brightness to lowest but they dont look different. On one of them the white looks much better. Its "more" white.
Can this be fixed or is this a hardware problem?

You mean they look different?
Afaik, SAMOLED screens display warmer colours after being used for awhile so a brand new screen will display cooler colours so that the white may appear blue tinted, this gradually disappears over time as stated above.

This is the correct technical explanation. New screen appear blueish and white. It gradually turns warmer upon use. It's due to the degradation of the blue-making organic compound.

Enough I can't find for S Amoled but oled has a 5 years life based on 8hours on per day. I guess already in a year or two you will change your phone

Color Calibration

Any suggestions on how to adjust the display colors on the V500?
I feel that the bluish tint is a bit to much on the tablet
Thanks!

Lucky! I wish mine had a bluish tent... Wanna Trade? Lol (I much prefer blue for some odd reason) mine has a yellow tent (warmer) to It, I use the root app called trickster to a just it. You will need to change the cpu governor to performance but it works.

lol .. didn't know there's such variability in the device (that's not good). I haven't rooted mine yet, but will probably do so very soon to get this app (and many others!). Thanks for the tip!
Also there an app called screen adjuster in the play store that works well. What's funny is mine had the yellow tint and changing ROMs made a huge difference

Screen Adjuster does the magic on Asus Memo Pad FHD too.
The screen is too "dirty" (brownish) even turn the Splendid to -10. However, with the combo with Splendid (-5 in white level and +3 on color depth) and Screen Adjuster (+2, 0, +12), problem fixed.
On top of that, you don't need root to make it work.
Frankly, Android should have RGB and Gamma tuning in Developers section (like Windows) to let users to fine tune white balance.

Installed Screen Adjuster, setting put to +2, 0, +12. What about this part on Splendid (-5 in white level and +3 on color depth)... Can't find any setting for this. Please advise.
Found the settings of +2,0,+12 to really help with that yellowish tint. It looks much closer to my G2 screen now. Thanks.

Actually, color temperature is more accurate on the gpad (6153k) than on the g2 (7092k). Your screen has to be calibrate close to 6500k to display a perfect white. 7000 is too cold as most lcd outhere, your eyes are accustomed to see bluish colors on your TV and your other devices.
The main issue on the gpad calibration is the gamma setting as shadows tends to be too dark. Set contrast on -25 with screen adjuster will reveals a lot of details in the dark areas of a picture.

Thanks a lot!
That configuration gave me a real natural look and nice whitey whites.
I was using 0,0,14 before (as I thought red adds up to the yellow) and it gave me a too bluey look.
Now it's perfect!
Most of the gripes I've seen on xda with the non-GPE version are around a yellowish screen and the brightness is too low.

Screen mode

Hi all
Can anyone suggest a screen mode?
No because it's a matter of personal taste. I tend to not use adaptive cause the colors are too saturated. AMOLED Cinema is the more pleasing one to me on this phone in particular
I really wish I could adjust the whites on basic or decrease the saturation on adaptive. Any ideas?

You can adjust whites on adaptive with the rgb color balance slider. I turned the white point temperature right down to 6800k. The default is around 7500 I think.

Sure, but adaptive is too saturated for my taste. I'm sticking with basic for now, but the white is quite reddish. I'm not exchanging this again as it takes over 2 weeks :c

Did you try going into the advanced setting and lowering the red with the slider?
Edit: never mind, read your comment too fast and thought you were talking about adaptive being too red.

Can someone tell me this exact part?

Hi guys
I have a used V20 but the colors of the icons etc are quite dull compared to my wifes V20 and also the whites are more yellowish when compaing side by side. Which part of the phone affects/determines the LCD colors? Is it the digitizer itself or does it have to do with the mainboard producing the colors?
Thx!!

Thx
Activate the high contrar mode either with the high contrast theme or the option(i dont remember where it is in the settings)
Sorry for the double comment

Yes i have it turned on. Screen colors are still quite poor compared to my other V20. Colors seem faded a bit.
Im thinking maybe its due to age or wear. But our phones arent THAT old.
