Hello, I am having an issue with my newly purchased AMD R7-360. This is my first AMD card after several Nvidia GPUs and I am having the following problem.
A little background: I have a Samsung KU6300 40" 4K TV I use as a main monitor. This TV supports 4k @ 60hz, and I previously was using an NVidia GTX 1060 which supported HDMI 2.0 and had no issues using the display at 4k @ 60hz in desktop on Windows 10 Pro.
Problem I'm having: With the AMD R7-360, when i switch resolutions to 1920x1080 (doesn't matter if I switch from 3840x2160 or 1600x900 for example) the refresh rate always goes back to 29hz interlaced. I can go into my settings and change my refresh rate to 60hz and it will take and run fine. This is an annoyance because I keep my desktop display at 3840x2160 @ 30hz but playing games will cause the fps to cap at 29 because of this.
I am aware that the R7-360 only supports HDMI 1.4 and I should expect only 30hz at 3840x2160. The fact that the refresh rate always is defaulting to 29hz is causing a headache. If I set up a game for example to render at 1600x900 the refresh rate will set to 60hz. I don't know if there is something weird going on since 1920x1080 is 1/4 of 3840x2160? If I change my desktop resolution from 3840x2160 to say, 1600x900, my tv goes black for a few seconds then comes up in the new resolution with 60hz refresh, but I've noticed if I go from 3840x2160 to 1920x1080 the screen immediately changes and does not go black for a few seconds.
I have the latest drivers installed (17.7.2, minimal setup, no ReLive) and Windows is fully up to date and it's a fresh install, no previous GPU drivers. Any ideas on something to try? Thanks.
