2nd monitor regularly cutting out during full screen games
1st monitor is a old 1080p Dell connected via DP
2nd monitor is a Samsung mu7000, 4k HDR, connected via HDMI
Vid card is Nvidia 2080ti
When playing a full screen HDR game, every 5-15 minutes the 2nd monitor goes black for a second, appears to be switching modes, screen goes very bright for a few seconds, then switches back to normal.
I've swapped cables, changed refresh rates, tried different ports, changed chroma subsampling, borderless windowed. Still reproes.
Only way I've found to stop the issue is to physically disconnect monitor #1. Hoping there's a better way?
