I've been having issues with disappearing text with a new install of LibreELEC 9.2.6.
To combat this I opted to follow the custom EDID guide.
I tried both the built-in script and changing this manually (the machine reports that it's connected via DP-1) and both methods produce no video upon rebooting.
This is with an Intel NUC Bean Canyon NUC8i5BEH3 i5 8259U connected via a Sony AVR.
Now I'm stuck with having to put up with the GUI text disappearing randomly.
Does anyone have any ideas?
