I just built a new PC. Before installing AMD video drivers, the display looks perfect (1080p). After installing new drivers, the display is pixelated and slight flickering of letters and certain objects. The odd thing is that I hooked it up with the same HDMI cable to another display and it's perfect, so I'm guessing I can rule out the graphics card. Resolution is native and changing the scale, color signal, or resolution does nothing. Cleartext does nothing as it is not just text that is pixelated. The 2 displays I've tried are Vizio TVs, with the older TV being my main display that has the problem.
