I dont think its a faulty cable. It has happened in bf1 and overwatch (the 2 games I frequently play) when the screens turn off I hear an error message but I cant see what it says. I once saw it and it said rendering device has run out of memory. Dont no if thats still what the message says and if so, how to solve it.My specs are: gtx 970 strix, 16gb ram, i5 4460
