Problem:
Radeon Driver 18.10.2
In RGB444 / 4K / 60hz mode , I can't enable 10-bit color depth
The AMD control panel can see the menu for 10 bit option , but select the 10 bit will get back to 8 bit after monitor blink out for a sec
The windows 10 display information show the display mode still in 8 bits
Radeon Driver 17.11.4

But , the windows 10 display information show the display mode in 10 bits
