Rating: 4/5 Very good monitor April 15, 2022 Very pleased with this monitor. Colors are rich and bright. I haven’t taken advantage of the built in camera for FaceTime calls. I just needed as usb c to thunderbolt3 adapter for it to work with my M1 MacBook Air.

I would recommend this item to a friend!

Rating: 5/5 Had mine since they came out...still using...awesome display January 9, 2020 This is a great monitor that I've been using since 2012 shortly after release with my MacBook Pro. I've retired my MacBook Pro and am now using with the 2018 Mac mini with Apple Thunderbolt adapter. The is still even in 2020 an awesome display. I did have to replace the cooling fan ($40) but the DIY was simple and about 15min.
