Hi,
It's all in the title. I couldn't find any way of getting the UI to go 4k. The uppest I can go is 1080p 30fps, that's really low. I tried setting hdmi_enable_4kp60=1 in config.txt, but after this, the UI only occupies a quarter of the screen. That is really strange. And I have no new setting appearing. So I rolled back. I couldn't find any answer to this in this forum. Could someone help me please ? Thanks in advance and have a great day.
