Well as of recently my monitor (as of monday) my primary screen (dell u2711) has been plagued but very annoying random flicker.
Best to describe the issue would either be half/the whole screen blacking out on any active application lasting from a 0,001ms to 15sec pretty much. (be it a game/movie/benchmark , yet not on desktop)
First things first since i'm an OC nuthead i checked that first and even tried stock bios + stock clocks , this all made no difference.
Secondly tried a roll-back to older drivers but the issue persisted with every driver (went 4 versions back so yeah that can't be it either)
After that i used my secondary screen only and everything played/worked just fine there without any issues. (including with overclocks)
So thinking i've had the issue isolated i'm still stuck at this primary screen, to completely exclude it being a gpu issue i tried connecting it to both gpu's with two different sets of DVI-D cables to make sure neither of the ports/cables would be defect. (this was more an overkill double check , since i wasn't able to capture the issue on any printscreens even when spamming print screen at a full black screen for 15sec)
The next question is , have i explored every possible option to make sure the screen is in need of a RMA? (got it with limited warranty so it is even questionable if i get a new one/replacement)
Because packing/shipping this is going to take quite some time/proper packing/funds.
