I have my Pi 4 hooked up through my A/V receiver to an HD projector. All other devices correctly see the display device as 1920x1080, but Kodi shows 1280x720 as the video output. I've gone into the system settings, and there's no 1080p available. The list ends with two 1280x720 entries for some reason.

What happens if you connect the RPi directly to the HD projector?

I was going to gather a log, but now I have a different problem: Kodi appears to be spewing a CEC command to switch the HDMI input on my projector to the wrong one, continually. So I can't do anything with it because I can't see the UI.
I can see the UI if I hook it up to a different monitor, but I can't find any way to turn off CEC or reset whatever is messed up. Any ideas?

In the end, the resolution problem was a defect in the NAD T758. I had to wipe the entire receiver and reinstall its firmware, which of course deleted all the settings and calibrations I'd set up. But hey, now devices detect it as 1080p-capable.
For anyone who finds this thread: Avoid NAD products. This is after a year of (a truly pathetic) experience.
