Windows 10: Advanced display settings shows 6 bit colour depth with AMD vega-8 graphics

I have a Honor MagicBook laptop. Advanced display settings shows the colour depth as 6 bit when all the display drivers amd are installed. The colour looks washed out for some reason. If I remove the driver and go back to Microsoft Basic driver, it shows 8 bit and the colour is correct. In Ubuntu also the colour is correct. Only in Windows 10 latest update upto July 2021 with AMD drivers, it shows 6-bit and AMD Radeon settings does not give an option to change it to 8 bit. How to correct it?

:)

 

Color bit depth is at 6-bit on Display properties of Windows 10 pro

Try the below suggested steps and check if the suggested options are available to change the Color bit Depth value

1. Right click on the desktop and select NVIDIA Control Panel.
2. Expand the Display, and then highlight the Change resolution.
3. On the right side, check if there is 8 bpc listed under
   Output color depth.
4. You may select 8 bpc and restart the device to witness the changes.

Color Bit Depth is Stuck at 8 bit - Display adapter mode says 32 bit

Build 17.rs_prerelease677.180520-0940 is my current release. There was an update that failed and changes were rolled back.

In Settings:

Now in the Windows Display settings says "Resolution: 1920 x 1080 (recommended)"

Click on "Advanced Settings" Both monitors say "Bit depth: 8-bit"

Click "Display adapter properties (either monitor)"

AMD Radeon HD 7700 Series Properties opens.

Click "List all modes"

"1920 by 1080, True Color (32 bit), 60 Hertz" is selected!

The Display, Desktop, Photos, Movies are in 8-bit 256 Color mode and look really bad!

How to fix this?

Windows has problems responding at times.

I rolled the Display driver back to a previous release... Had to reset the computer because it froze.

On reboot it is on the rolled-back driver level, but still wrong.

 

Windows 10 defaults to 8-bit color depth automatically.

Looking at the image from Windows 10 it looks like a typical Windows 10 display.

What does a photo look like when displayed by Windows 10, do you see colour detail you would expect. Mine show a colour depth of 24 bit (even though windows Display shows 8 bit) and the details of the image look fine.

Searching the Internet for "windows 10 display 8 bit" shows many questions and some explanations.
