Playback of 4k-Movies doesn't worker propperly - Raspi4

Helios61 · September 16, 2022 at 12:23 PM

Hi community, i hope you can help with solving this odd issue.

I've installed and set up Libreelec on the RASPI4/4GB. So far everything is working fine and without any problems (1080p, 1080i, TV headend client....). Unfortunately, I ran into a odd issue: 4K movies are only displayed in the upper left quarter of the TV. However, the TV switches properly to 4K/24 mode. Screenshot and log link are attached.

Best regards

Helios

I've never heard of this issue. Possibly you have some invalid/corrupt settings?

Can you try:

Code

systemctl stop kodi
mv ~/.kodi ~/.kodi_back
systemctl start kodi

and then play the file? If it doesn't help you can put thing back:

Code

systemctl stop kodi
rm -rf ~/.kodi
mv ~/.kodi_back ~/.kodi
systemctl start kodi

(or if you have a spare sdcard, just check if a clean install has the issue).

I remember having a similar problem long ago on someone else's setup and it was solved by messing with hdmi_* in config.txt.

Ref: https://github.com/raspberrypi/do…_txt/video.adoc

Sorry that I can't remember exactly what I did but hope you can find a solution there.

"Long ago" probably means using the legacy video pipeline which means the hdmi_ tweaks in config.txt aren't relevant to the now-different video pipeline used in current LE releases.

I was facing the same issue; 4k playback only appearing on the top left quater

I tried downgrading to 10.0.2 and the problem persisted; hence I installed from scratch; it worked for a while till I changed some settings

I was later able to narrow down the setting in question to the following

System -> Display -> Set GUI resolution limit

1080 (anything else would yield the issue after reboot)
