Review on UPERFECT Portable Frameless 15.6" IPS Monitor, 1920X1080P, 60Hz, Wall Mountable, Anti-Glare, Built-In Speakers, 156KICKSTAND by Minas Patterson

I love it for everything, a good picture is good in everything. BUT the high-pitched rumble it emits is unreal. It hits my inner ear so badly that I can't help but try to focus on work. The only way to stop the buzzing is to turn the brightness down to zero...so you can't see anything. Revain replaced it and the new one has the same problem. Really sucks, otherwise great, light weight, good screen. UPDATE: The company contacted directly and definitely delivered. Monitor repaired, works great! All the great features and no buzz. Highly recommended
