RPi4 stuck in 1920x1080p on a 4k monitor

  • I am using LibreELEC-RPi4.arm-9.80-nightly-20200904-89c7562 on an RPi4 with a 4k monitor but seem to be stuck @ 1920x1080 from Display>Resolution. My /boot/config.txt does not limit it there so I am wondering where else a limit could be introduced.

  • I took the file from here and replaced it but I still have the same limitation of 1920x1280.

    I reimaged the card entirely using LibreELEC-RPi4.arm-9.2.5 and I have 4k available now. Then I updated to LibreELEC-RPi4.arm-9.80-nightly-20200904-89c7562 but only get a black screen. This was a known problem with older milhouse builds. I will search and see if I can find a solution or start a new thread.
