So I have my PC connected to Philips 49PUT4900 TV with a displayport 1.2 mini to hdmi 2.0 adapter and a hdmi 2.0 cable from my AMD HD7950 graphics card and its currently working on 4k 30hz even though it should be 60hz at the same resolution. I have read somewhere about problem being amd drivers or chroma form, but I don't really understand what that is or how to adjust it ann the new amd software doesn't have any advanced options to configure. Can somebody please help? Also, I tried uninstalling amd drivers and the tv worked on 4k 64hz O.o , but I had to install them again because my monitor wasn't showing any picture. I found out the tv is not them problem as it can do 4k 60hz at any hdmi port, and the same applies to the adapter and the cable. Can somebody please help?
