I bought this monitor about a week ago and up until tonight it has been fantastic. I was playing Halo Infinite and it suddenly started flashing like crazy and wouldn't stop (like, seizure inducing flashing). I turned it off and back on, the flashing stopped but now there are vertical lines on the screen. The black void is there even on the ASUS power up splash screen, so I don't believe it to be a PC/GPU issue. I've unplugged all cables from the monitor and their sources and reconnected but the lines are still there.
Anyone have a similar issue or know what might be going on?
Edit: Apparently I don't know the difference between horizontal and vertical.
I have 2 suggestions
Since you bought the monitor a week ago, you should be able to return it, given it meets the return policy of where you bought it from. Hope this helps!
Thanks for the suggestions. I can't try a different power cable, it doesn't use a typical monitor power cord plug and I don't have an alternate. I don't think a different display cable would help since the lines are there even if no display cable is connected. I suppose it could have overheated but it wouldn't have been due to external factors. It's in an open area in a cool basement (it's not humid either so moisture isn't the issue). Heading up tonight to swap it for another one (same model).
Yes, if it's appearing even without a cable from monitor to PC, definitely bring that back in for a return/exchange within the 30 day return period.
