have you tried the monitor on a different device ?
#Monitor Problems
upbeat kernel
does the flicking change if you wiggle the port ?
Tried another input ?
i think its more likely to be the monitor (and less pricy to replace) but i would try both - if it still persist on a different input on the monitor then is nearly impossible to diagnose via discord, if you can reproduce the issue on another monitor then your GPU said goodbye, but i would try anouther output on it just in case only one port is affected
Thats good
you probably could repair the monitor if you got some electro tech skills but if you don't you could try it but to be mad at yourself when you fail
wouldnt that still be under waranty ?
one last super obvious thing - did you use the same cable for all tests?
is the cable in the test where the problem accrued the same
sorry not a native english speaker.
have you just tried switching the cable out
would have been to easy - sorry that i wasn't more helpful

Yeah if it's doing that even unplugged i'd assume the processor in it's shitting the bed, should definitely RMA it if possible
An unfortunate death to a soldier 
Ye what gives it away is the "artifacting" going on top of the OSD elements, that should basically never happen on the display's elements unless it, itself, is bad
Also W csgo moment xD
