Does Radeon RX 570 support 10 bit? I'm about to buy a Dell 34" U3419W monitor, and wonder if Radeon RX 570 support the monitors 1,074 billions colours (10-bit)?
Yes 10bit is supported, but only if the application is using DirectX and is running in exclusive full screen mode. If the application is using OpenGL for example, or running in Windowed mode, you would need a WX/Firepro/Radeon Pro graphics card for full 10bit support.
Polaris' display controller is capable of 10 bit color at 4k 96hz. The RX 570 is a Polaris card.
