Just got a Sony Bravia 49xd8088.
I have it connected to my PC which has the following graphics adapter,
AMD Radeon HD 8670D + HD 7000 Dual Graphics
Now I think that card does output to 4k, and the TV itself is 4k, but I cant make it work. The HDR seems to work, but it wont activate 4k. When you look at the info for the source it says 1080p and thats the maximum resolution the PC seems to go to.
Anyone have any ideas? I'm using an HDMI 2.0 cable and all my drivers are up to date.
