I have a radeon R7 260 using the CAC-1070 to connect to my XBR65X850C. the TV should handle 4k 60Hz 4:4:4 and 1080P 120Hz over Hdmi 2.0 but neather of these resolution work. if I switch to 30hz 4k work and 60Hz 1080P but I game at 120hz 1080P and work at 4k 60hz with 4:4:4 being a must.
for the life of me I cant figure out how to get this to work. I see lots of people saying with Nvidia card to switch between RGB and ycbcr but I don’t get those options with AMD.
I seem to be able to do 4k60 4:2:0 to my vizio 70P but it doesn’t support 4:4:4
I will be pulling one of my gtx 970’s from my gaming rig and testing the tv with the native HDMI 2 port in the next couple days but I would rather just fix the AMD problem as its a PITA to get the cards out of my gaming rig.
