I usually just switch it from auto to 1080p or whatever is available and that fixes it 90% of the time, sometimes it takes a second or 2 to fix the quality though.

I've got:
R720 w/ 2697v2s, 12 hdds Some Intel 2011 box w/ 2667v2s A custom AM5 server w/ 7700x, 8 hdds An old Cisco enterprise 48 port (&4 SFP+) switch It seems to hover ~800w.
I'm looking into replacing a lot of it especially the Intel server because it's used for just pfSense.
