I recently tried to use my RX 480 graphics card on a 28" 4k monitor by Samsung. The HDMI worked great at 30hz but the 60Hz input for Display Port and the 60HZ HDMI cause screen flickering. (Well my screen flashes to no picture and then back again in a moments time repeatedly) Graphics card does support this resolution and hertz setting so what am I doing wrong?
I should mention that no flickering occurs when normal web surfing or even typing this article. Only when streaming video and gaming.
