Frankly, going from LibreELEC to OpenELEC to LibreELEC without making xorg.conf changes makes no sense at all to me.
I didn´t go from LibreELEC to OpenELEC to LibreELEC. It was just from OpenELEC to LibreELEC, I made a new clean install of OpenELEC once I gave up from finding a solution.
Sorry but I don`t know how to make changes in xorg.conf, neither which changes should I do.
This is the xrandr after a clean install of LibreELEC

I have enabled "Blank other displays", it is connected to the TV via HDMI, but the resolution is 1280x800p and if in monitor options I select HDMI what I get is a black screen.
I was using OpenELEC without this issue, that is why I made a new clean install of it and then update to LibreELEC
The xrandr after the update is:

Now I can select HDMI and 1920x1080P, full screen not only the top left corner.
If you need more details please ask. Any help will be wellcome.
Thank you
