Review on Dell U2520DR UltraSharp DisplayPort Certified QHD Monitor - Crystal Clear 2560x1440 Resolution by Richard Lovelove

Sent this monitor back during the day because of the horrible coil squeak (high pitched tone) that would become very noticeable when the brightness was below 70%. It seemed like an uncommon but still possible problem when I read the reviews before buying, but I figured I was lucky with a device that didn't have this problem, or I was hoping Dell would on recently released models fix I don't think so. I guess the positives are that the monitor is really bright because the first thing I had to do was turn the brightness down and the colors looked good too, but I have an old Dell Ultrasharp which I'll keep using as best I can to 40% brightness without going crazy with coil squeak.
