I have the exact same problem: got my monitor on Tuesday, and on Thursday after a 3 hours gamining session I was browsing on windows and it went black. I powered it off/on, screen ok for 30 seconds, then goes black again. Maybe it's too hot... anyway it's really bad. I can replace it, but seeing the other guy saying this also happened for his 2nd monitor, and seeing flickering (only when loading a BFV map, never in game actually), and seeing that image quality is less nice than my old IPS 144hz 1440p Acer XB270HU makes me think I will wait for the new IPS models... Too bad because I kinda liked the curve and responsivness of this screen.
