Hi guys, I have a 5.1 Mac Pro with RX580 connected to a Acer B276HUL display via DVI cable and all was fine. I had to move the Mac Pro further away and needed a longer cable to connect it back up but didn't have a long enough DVI cable. So I tried an HDMI and DP cable and both of them created a very bad image. Specifically the text and icons look over sharpened and perhaps didn't have any AA applied to them? What I have tried: enabled/disabled font smoothing tried to manually set font smoothing checked display settings reset display to factory settings Both HDMI and DP cable produce a normal image under Windows 10/BootCamp! I'm absolutely baffled by this. Anyone have any tips?
