This is a very specific issue and hopefully someone knows what's happening. I have two monitors connected on my PC and when the displays go to sleep while a specific app is running, the second monitor starts an on/off cycle and there's no way to prevent it. Every 30 seconds the secondary monitor will shut off (or flashes black) and turn right back on, and only a restart of the machine will fix it. I believe it's when I have PureRef or Slack on the second monitor. I've found mentions of this issue and people say to use a different display port, different cable, etc. but this is software related. I haven't narrowed it down but my hunch is that it's PureRef, Slack or Spotify. When I don't have an app open on the second monitor it seems to not go into this cycle. Any hints on how I might isolate the issue, a system log I can view to investigate the cycle, or perhaps settings in Windows that I can alter to prevent it?
I'm running one Dell P2715Q as the primary monitor (set to main display) and one Dell S2721Q as the secondary. Both are connected via Display cables to a 3080 GPU.
