12 bit

Hi and thanks for reaching out. I hope you’re doing well. I'm an Independent Advisor and a Microsoft user like you and I'll be happy to help you.

Kindly try the steps below;

1. If there's a disc in the console, eject it.

2. On the console, press and hold the Power button on the front of the console for 10 seconds to turn off the console.

3. Press and hold the Power button and the Eject button until you hear a beep to turn on the console. You’ll hear one beep right away and a second beep 10 seconds later. The power light will flash on before the second beep. Don’t let go until you hear the second beep or see the console start-up in low resolution mode (the Xbox startup screen will appear slightly pixelated).

NOTE: If you have an Xbox Series S or Xbox One S All-Digital Edition, press and hold the Xbox button and the Pair button instead, as your console doesn’t have an Eject button.

4. In either case, this will start up your console in low-resolution mode (640 × 480).

- To change this setting, press the Xbox button on your controller to open the guide. Go to Profile & system > Settings > General > TV & display options, and then select the resolution that you want from the options under Display.

I changed the colour settings from 12 bit to 10 bit and that seems to have solved the problem for me

You may have set your "color depth" setting too high, likely at "36-bits per pixel (12-bit)". Choose the next option, "30-bits per pixel (10-bit)".

I experienced this same problem when I initially set up my Xbox One X on my 4K/HDR TV, and fixed it by setting it to 10-bit color. I think 12-bit is for Dolby Vision TVs.

Mine does the same thing but it shows 8 bit and 12 bit. Also when I go to Netflix there is no 4k.
