Is a 4K MagicMirror possible?

Impossible with rpi. But other sbc or pc might.

@Sean That’s what I figured. There are boards like Rock64 that support 4K output. Do you know how compatible MagicMirror is with such boards and if the MM software itself can output at 4K?

I didn’t test it. But Electron itself has ability of using 4k resolution if chromium supports it properly. However I can not confirm anything…
For Magicmirror, its just html, so if electron and chromium(or any other webkit) could handle 4k, Mm could also.

Thanks for all the feedback on this. I noticed an earlier thread by you regarding MM on the Asus Tinker Board. How has that worked out for you after a few months?

Based on what I’ve read, the Tinker Board supports 4K outputs but can only playback 4K video using their bundled program with hardware acceleration. Since MM is mostly static text and images, does that mean it can drive a 4K display?

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.

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.
