> 2020 release?
Probably. It's Windows 10 build 2004 or something.
The mac I have is mid-2014 w/ Mojave (also Catalina), and I'm using the hdmi out. It seems to remember the display, moves the applications I had on it last time to it, with all the other details like wallpaper scaling settings. It takes maybe 1/2 second to display.
