I tried Luna Display, lagging is too bad. There is no video input port //@Anonymous: Compared to the $1299.99 stand-alone Apple 5K monitor, this is a good deal, if want to use it as a 5K monitor. Also, the 2020 iMac 27' can easily upgrade RAM, but cannot upgrade SSD at all. Overall, still, this is a good deal for graphics-heavy user such as a photographer or videographer.

2015 or later iMac does not allow using as a target display mode.
