The monitor is an acer predator x27u, this started last night when I went to switch my monitor over to HDMI input from display port after powering on my xbox. It basically turned itself off and now any time I try to turn it on it displays the Acer Predator logo like normal, and then turns off. The power light will show solid blue, and then flicker blue/orange for a second or two before going completely off. My PC still recognizes the monitor as a display even while “off”, and I can drag things onto that screen on my desktop even though I cant see it.

What I’ve tried:

-unplugged and replugged every cord numerous times

-plugged monitor directly into the wall

-plugged monitor into different power strip

-too many power cycles to count, of the monitor, my pc, and my xbox

-uninstalled and reinstalled monitor profile on my pc

-updated gpu drivers

-Tried a different power cord that works on my other monitor (it has to plug into the AC adapter box which then plugs into the problem monitor, so thinking the AC adapter could have shit out— Ive got a new one coming tomorrow)

-Cursed angrily

-Smacked the top of the monitor, my grandpa used to this to the tv and it would work

-tried the flash light test to check for blown capacitors, not suspecting that

-Acer logo looks completely normal for the brief moment it pops up so the monitor does not seem broken?

-The issue still happens when the monitor is only plugged into power with no other cords plugged in, so theoretically an issue with the monitor itself

My main two thoughts are that it’s either a problem with the power cord, specifically the AC adapter box part, or that I have somehow gotten the monitor stuck on the wrong input. I was half asleep when doing this so I could have picked the wrong input and it could be bugging out and not automatically switching to the correct input. The problem I ran into with this is that since this monitor only has the single external button to pull up its menu settings, I have no way of manually changing the input. So if this theory is possibly correct then that seems like an awful design flaw and I’m not sure how to get around it or force the monitor to switch back over to DP or HDMI.

Im hoping it’s just an issue with the power cord, but I am a little confused as to how this only started at the exact moment that I switched inputs. It’s one of those things where I feel like the answer could be really simple and make me feel really dumb, but because I am overthinking it I just haven’t found the simple answer yet. I spent 3 hours last night trying to figure this out, please help me before I go insane
