What people are saying
Rated 5 out of 5 by from Great quality picture on the monitor I originally bought one of these monitors for my wife when her monitor died. I liked it so much that i decided to replace my full HD monitors with 2 of these 4K monitors and am extremely happy with the results. I use my PC to watch TV and play back movies and the picture quality is amazing,.

Can use this monitor with an Apple Mini 2019 ?

Asked by: JonathanC11
I have this monitor connected to a 2018 Mac Mini (the machine you reference). It works okay but the internal graphics card on the Mini (Intel 630) is underpowered and makes the system buggy at resolutions much higher than FullHD (1920x1080). For reference, the Unigine Heaven Benchmark set to Medium comes up with an average Framerate of 2.3fps at 3840x2160 & 13.6fps at 1920x1080. If you want to use this as 4K resolution you'll probably want an external graphics solution. Also, if you want to use a TB3 to DisplayPort cable (or any cable that didn't ship with the monitor) it nags you every time you turn it on to use the cables that came with it.
