[SOLVED] 8.2.2.2 LePotato 1/4 screen occupied in 4K

invik · December 30, 2017 at 8:55 AM

Hello,

I have an issue on LePotato build.

The kodi interface scales to 2160p in 8.2.1.2 but not in 8.2.2.2.

The interface only occupies a quarter of the screen in this case.

When playing a 4k movie, the kodi overlay and subtitles are displayed as if the resolution was still 1080p.

I have restored a backup configuration that I made on 8.2.1.2 and it does not fix the problem

Here are some photos: Imgur: The magic of the Internet

HDR works fine too.

On a positive note The remote through lirc works great on this build. I had to activate lirc in libreelec services configuration addon and that was it. Great work

invik I moved your post to a separate thread, please create a new thread when you encounter an issue like this - and remember to post logs.

For now, please try this: open boot.ini in the root folder of your SD card and replace outputmode with hdmimode in the line LibreELEC.tv/boot.ini at 8.2.2.2 · kszaq/LibreELEC.tv · GitHub

Hello,

Thanks for the quick answer. I did not know where to post to be honest since many users report problems to you directly on the main post

Anyaway, even your suggestion does not produce the expected effect, I will try to get the logs.

It looks like a bug in setting free_scale but it shouldn't happen as SYTEM image is basically the same for all my S905(x) builds and nobody complained about the same bug. Can you post a result of ls -l /sys/class/graphics/fb0 and grep . /sys/class/graphics/fb0/free* when screen is set to 4K?

To rule out some magic happenig due to incorrect cmdline options, please update to 8.2.2.2a (it should happen automatically), run this command after update: mount -o rw,remount /flash ; mv /flash/boot.ini.update /flash/boot.ini and reboot.

Hello,

Good news, the last command fixed the problem. So it seems some magic is happening in cmdline options

invik If I understand, 8.2.2.2a with new boot.ini solved your issue?

invik · December 31, 2017 at 12:31 PM

Yes it did.
