5700G with Gigabyte B550I Aorus pro AX.
I want to run 3x 4k 60FPS screens - LG 27UP650P. One is fine on displayport, two on HDMI do not work properly and are stuck on 30FPS. I have used Adrenalin to set the display to 8 bit. This is supposed to be doable with HDMI 2.0, however, it does not let me set the screen to 60FPS (only 29.97). I tried setting custom resolution, but I didn't see how to make it work, the screen remained on 30FPS even though I typed 60 FPS there.
Is there a way to make it work (without buying a GPU)? Thanks!
