Is a 4K MagicMirror possible?

As i know atb can handle only special video format as 4k. But frankly, I don’t need 4k for mm. And I have no 4k display to test. 4k display is too expensive for mm :)
But I believe if Electron and webkit in device could handle 4k as output, mm could be displayed as 4k. I think there is no reason it coudn’t.

I’ve read Electron on windows 10 could hanlde 4k display, that means there is possibility for X-nix system also. You’d better ask to Electron expert communities about this.

Impossible with rpi. But other sbc or pc might.

Sorry to bring an old thread up from the dead but since this came up as the first result when searching on google thought I would reply to it.

4K does appear to be possible on the Pi. Set one up this weekend on a TCL 4K display. Is very stable and works well even with 3 RTSP streams also running on the page. Obviously the font becomes very small with the 4K resolution so had to change font sizes but not too difficult.

Wow, nice information.
My previous knowledge was from https://elinux.org/RPiconfig
Anyway, I found some others have tried already and got success.

Anyway 4K display is still too expensive for me to use as MM. :D

@Sean I picked up the TCL 43” 4K display at Best Buy for $215. Not too bad.
