Good day,

A couple of months ago I purchased the Dell P2715Q, and with some delay it got finally delivered. Well, it appeared the first monitor was broken and had a blue vertical line on the screen. Dell replaced it without any trouble, so thank you for that. However, now with my second P2715Q I have got a new problem. Running in 4k resolution, 3840x2160 60 hz, every now and then the monitor turns to black for a second and then it goes back on again. It happens randomly, but it appears to happen more often when gaming or watching series/movies. It does happen when idle aswell though, or just when browsing. Sometimes it happens only once in about 15 minutes, sometimes it happens twice or three times in one minute. Oh yeah, connected with a DP cable. So, any idea what could be wrong? Anyone else have this problem? I'm probably going to test the monitor at a friends place soon, see if my (new) gpu might be causing it, but I doubt it. I had the black flickers on my previous P2715Q aswell and tested that at my friends place aswell. There the black flickers happened too.
