Afaik it’s a displayport issue (because DP has the feature to detect if PC is on). I’ve had the issue on multiple monitors that it wouldn’t turn on the next time I booted the PC. After a lot of unsuccessful googling I finally found that the pc off-> monitor off -> pc on-> pc doesn’t see monitor -> monitor stays off apparently happens because of a capacitor not discharging properly, getting the monitor stuck in “pc off” state. Flipping the monitor power switch (or disconnecting the power cable) for 15-20 seconds has so far always fixed it for me.
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.
Had the same behaviour with an acer monitor, that shit definitely flows from the same factory

But maybe there are other reasons too.
