RPI4 NOOBS won't display after switching to 4k60p

Thu Apr 16, 2020 11:13 pm

After switching to 4k60p, when I reboot I can't see NOOBS. My TV just says no signal until it gets to the OS. If I switch to 4k 30hz or 1080p and reboot it works fine. My issue is I have 3 operating systems installed, and without being able to see NOOBS, I can't switch between them.

Try adding a config.txt file to your NOOBS partition and force the display mode using hdmi_group and hdmi_mode etc.

That didn't work. I've somewhat fixed the issue though. Even though I couldn't see it, I hit shift to enter recovery after rebooting, then pressed 2 to put it in HDMI safe mode. Now when I reboot, I can't see the splash screen, or the 'hold shift for recovery' screen, but the OS selector does come in low resolution after 15-20 seconds.
