I got my P4317Q in Aug 2016, it was that early faulty A00 revision with PWM (flicker) issue. I took a flickering video on the phone camera with lowered exposure and filed a warranty ticket. Local (EU) Dell service center picked up the display, confirmed an issue and one week later I got a new screen of A01 rev. from Germany with no issues. Superb monitor, just make sure to get A01 rev.
