Cant get Radeon 7770 at 4k 60hz

[Skaterforeva1]

Hey guys I just bought a Samsung 50inch UHD TV. It's a KU6300 series and I cannot get my computer to run 4k at 60hz (which causes terrible lag at 30hz). I bought a display port to HDMI adapter and HDMI 2.0 cord. The specs of my GPU say it will run 4k at 60hz with a HDMI 1.4 port but it wouldn't do it alone so that's when i bought the adapter for the display port. It will display 4k but in the display setting it will only allow up to 30hz. I tried creating a custom resolution is amd setting and it said that it was no compatible. Any idea's on what to do? I have unistalled and reinstalled the graphics driver with no success. Any suggestions would be greatly appreciated.

Graphics Card: Radeon HD 7770 1gb
Specs

CPU: AMD-FX 6300 Six Core Processor 3.5Ghz

Ram: 8Gb DDR3

TV: Samsung 50in 4k KU6300

Any help would be greatly appreciated and Rep+

Try to look for an option that says allow resolutions not supported by the Display or something like that and enable it. I know Nvidia has an option like that, which solved an issue I had similar to the one you're having? Maybe the AMD drivers have a simular option?
