I bought a Dell S2721QS last year March RM1369, display was nice until last week it had total blackout. Also I had issue with connection while i do daily online streaming, the monitor will suddenly blackout / show support issue warning for few sec then turn normal which is so frustrating. Its a bug.

I never use dell product before but will never buy dell product again. Bad product quality. Maybe I just receive a defect item but nah. Just skip dell next time.
