Review on Dell S2721QS Ultra Thin DisplayPort Certified Pivot Adjustment, Curved, High Dynamic Range, Tilt Adjustment, HD by Joe Hernandez

It seems like a good monitor that does 4k60. However, I had to return it because as soon as I plugged it in, I got digital/electrical noise in my reference Yamaha speakers. I've tried plugging the monitor into a separate outlet, but to no avail. I also tried moving the speaker away from the monitor but the sound didn't change or decrease. I think it's a nutritional issue.... This monitor has a built in power supply while the previous one (Samsung) and the one I replaced it with (LG) have an external power supply and make no noise at all. Connected to a 2018 MacBook Pro so maybe Dell and Apple aren't playing well or something. It's kind of a niche issue, but if you've got sensitive speakers, beware.
