On macOS the internal display is on, while on Windows I disable the internal display by telling Windows to 'only display on second display'. Lowering the refresh rate in macOS to 120hz seems to totally cure the issue. I'd say about once every 10 minutes or so.

The screen wouldn't go fully dark or anything, just kind of blink, and I could sometime briefly see graphic corruption as it blinked back to normal.Īfter further testing, in macOS the screen would glitch like this fairly regularly just browsing the OS. Sort of as if the monitor briefly lost connection for a moment. The monitor worked great at first in Windows, but I noticed that in DOOM I would get occasional graphical glitches.

Recently I purchased a Nixeus EDG27 144hz 1440p Freesync monitor. I use this setup on a 2017 touchbar MacBook Pro running macOS 10.13.3 and an HP Spectre 13' (8th gen Intel) running the latest stable Windows 10 Pro updates. My setup has been shockingly problem free so far. I'm running an Akitio Node Pro with an Asus Strix RX480 8G and a Cable Matters 6.6ft 40Gbps cable ( )
