I know that a lot of people have written extensively on the problems of outputting 4k video from the Raspberry Pi. I have a similar, but related question, can the Raspberry Pi simply output static images to 4k?

I ask because I'm building a reconfigurable digital gameboard and I would like to make the resolution as high as possible.

Yes it can

This forum user got 4k HDMI output working on their pi, and shared a sample config file. Simply use that config file, and display the images as you normally would, they will display at 4k.

    This seems to be only at 15 Hz though, which is pretty tricky. – Mike Battaglia Jul 7 '18 at 20:15
  • Very good point, however the application is for static images, so frame rate shouldn't be an issue – nkizz Jul 10 '18 at 2:03
