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?

Thanks for the reply. Didn't try that yet, but hooking it up to an HD monitor yields 1920x1080.

I thought maybe it was a refresh-rate problem, but the projector can handle 1920x1080 at 60 FPS.

I wonder where the blame lies here. It's weird that Kodi shows two entries for 1280x720 in the resolution list, and no 1080.

To receive meaningful assistance you will need to provide a full debug log.

The instructions are here... debug log (wiki)

If you are using the Basic Method, then ensure the following is applied...
1.Enable debugging in Settings>System Settings>Logging,
2.Restart Kodi
3.Replicate the problem.
4.Upload the log to Kodi Paste Site manually or use the Kodi Logfile Uploader. (wiki) With either method post the link to the log back here.

If you are using the Advanced Method ensure you have correctly created and applied the advancedsettings.xml file (wiki)

In both instances, you should see the word DEBUG throughout the log.

Note: Full logs only. No partial or redacted logs
Do NOT post your logs directly into the forum. Use the Kodi Paste Site. Post the link to your pasted log in the forum

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?

OK, I found how to disable CEC; I'd like to know how to stop it from issuing this erroneous command, however.

Here's my logfile for the resolution problem: http://paste.kodi.tv/amorohohar

I hooked the Pi up to the projector directly and got 1080p. If Kodi can't play through a receiver, it's a pretty crippled media player. Here's another report of the same problem: https://forum.libreelec.tv/thread/20979-...post141820

I think the problem is with your receiver's edid.

These resolutions are what your receiver reports it supports when connected. If it doesn't tell us it supports 1080p we won't use it.
It's also likely the cause of the CEC issue (the edid reports which physical hdmi port it is connected to).

You might want to check the manual to see if there is a "direct" mode where receiver doesn't try to generate it's own hdmi signal with overlays.
Also check if it's possible to update firmware.
Also try powering on projector first. Then the receiver. Then the Pi.

If this all fails you can fake the edid. Follow: https://kodi.wiki/view/Raspberry_Pi_FAQ#...d_on_first
but capture the edid to file when directly connected to projector, then you can use the edid on sdcard when receiver if connected back in.

Thanks for taking the time to look at it, @popcornmix 

At first I thought the Pi and Kodi were the only combo having this problem, but I just checked my Nvidia Shield and it too only offers 720p through the receiver.

Looks like yet another NAD problem.

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.
