Unfortunately I have noticed too late that the monitor is a humming noise, not my PC. The 30 days have expired, the PC I have replaced by a laptop and the buzzing definitely not. Neither cable nor Factory Reset helped. The picture is great and everything else but the sound sucks. My fault that I did not previously took care of. Nevertheless, it makes the product an absolute letdown. If I'm lucky is Amazon or Dell accommodating, otherwise I have the Log Now the leg. According to Google, my monitor is not the first from the series with the problem.
Definitely a great product if you are caught not B version.
