The kms driver for the official 7" display is still WIP and has several known issues. See eg here Full KMS does not work with pi4 and official touchscreen on kernel 5.10.1 · Issue #4020 · raspberrypi/linux · GitHub - RPi forum also has a couple of threads about it, eg this one RPi3 / VC4 KMS driver / 7" display = blank - Raspberry Pi Forums

opjenexus please remove all banned addons and repositories - best do a clean installation - you won't get any support here with these addons/repository installed. After that upload a log file where you reproduced the issue.

Berryboot was never supported as it causes tons of issues. Use NOOBS or PINN if you want a multi-boot system.

Use the stock config.txt that comes with LE10. The old hdmi_.. options in config.txt no longer have any effect so no need to re-add them.

Yes, exactly - Dolby Vision isn't supported. HDR10 and HLG work fine.

Try adding video=HDMI-A-1:1280x720M@60D to the end of cmdline.txt (after "quiet", separated by a space).

The boot partition is mounted at /flash, not /boot. See also https://wiki.libreelec.tv/configuration/config_txt

Are you by chance using an RPi4? If yes, we are waiting for this issue to be resolved KMS: blank screen after TV is brought out of standby on modes that need scrambling · Issue #4486 · raspberrypi/linux · GitHub
Just configure kodi display settings to 1920x1080 and whitelist the 3840x2160 modes, then you won't hit the issue when in kodi GUI.

Please test with the latest LE10 version - LE9.2 is EOL and won't receive further bugfixes.

Try adding video=HDMI-A-1:1280x720M@60D to the end of cmdline.txt (separated by a space from "quiet", everything has to be on a single line).
If it's a HD-ready TV then probably the RPi4 doesn't like it's native/preferred resolution (well known issue).

Please use the latest nightly build, this is a known issue and already fixed No USB on RPI 4 after upgrading to LE10 RC1

BTW: no need for a fresh install, you can just update your current installation (copy the tar or img.gz file to the Update share or /storage/.update/ folder and reboot).

We use the more modern in-kernel IR decoding, see our wiki for more info: https://wiki.libreelec.tv/configuration/ir-remotes
As you seem to be using an older IR receiver on the PC's serial port you have to manually disable the UART and load the serial_ir module as described eg here: Problems with lirc serial and autostart.sh

Thanks a lot for testing and reporting back, good to hear it's working fine now!
If you like you can update to later nightlies, we fixed a couple more bugs (and stopped enabling 4kp60 by default as that there's an unresolved issue). See the github commit log for details Commits · LibreELEC/LibreELEC.tv · GitHub - clicking on the linked pull requests in the "merge pull request ..." commits usually contains some more info about the changes.
It's always helpful for us if people test the latest nightly so we get feedback if we accidentally broke something.
But of course it's also OK if you just stay on the build that works for you and wait for the final release.

Please provide a debug log where you reproduced the issue with H264 files - the log you posted shows only a HEVC file being played and looks fine.

Ah, your cmdline.txt is wrong, you seem to have put "
drm.edid_firmware=HDMI-A-1:edid/1920x1080.bin" on a new line - everything needs to be in a single line in that file. You can drop that and make sure that
"drm.edid_firmware=HDMI-A-1:edid/edid-HDMI-A-1.bin video=HDMI-A-1:D" immediately follows after "quiet" (separated just by a blank).

Thanks for the logs, it's good to know that it works fine with the projector connected directly to the RPi.
Please do the following:
Connect RPi directly to connector and boot up LE. Then ssh in and run "getedid create". Now shut down LE and add the HDMI converter / audio extractor back into the chain and boot up again.
LE will now permanently use the (working) edid from your projector and everything should work fine.
