Hello Folks,
I have a Samsung 65" UA65MU9000

Currently my Resolution is 3840x2160 running at 60HZ

Radeon Software Version - 19.7.5
Radeon Software Edition - Adrenalin 2019
Graphics Chipset - Radeon RX 580 Series
Memory Size - 8192 MB

Core Clock - 1340 MHz
Windows Version - Windows 10 (64 bit)
System Memory - 16 GB
CPU Type - Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz


A  couple of problems. My videocard is running on a premium HD cable capable on doing 60hz, 4k, 10bit (Confirmed with my mate and his setup). But my Radeon settings wont exceed 8bit in ANY Pixel format. Furthermore I dont think HDR is working properly because windows 10 is darker with a grey mouse. My mate plugged in his rx580 and his pc into my cable and my TV and its doing 10bit for him. 


Here is my specs

Any help is appreciated.
