I’m not saying that’s not the case, but it has both hdmi and displayport, and it’s happening with both, had it on either one, alternating, both plugged in, nothing plugged in and then jamming either cable in there as stuff was powering on, I did eventually resign myself to having to yank out the power cable and plug it back in when it was misbehaving. Nowadays it’s just sitting in a corner, seldom used, should honestly toss it but it’s still sorta works, when it feels like it.
