Thanks for your reply.Thats interesting because the config.txt file you speak of simply does not exist on a standard libreelec installation
when the microsd card is viewed on a standard pc. Is the file hidden away somewhere, i am not sure where.
libreelec starts ups and run fine when i put the card back in the pi. The settings must be stored somewhere but
there is no config.txt file when the card is viewed on my pc.I am confused when you say i can create this file.If i create it the then where do i put it, how do i tell the os it exist
and to read it or does it look for it allready.
The sd card with libreelec is called RECOVERY on the PCThanks
I don't know what you're looking at, but I've just downloaded the stable img.gz for a pi2/3 and written it to a card. It shows up in windows as a Removable Disk (ie no label) and 100% contains a config.txt:

The config.txt sits in the root of the sd card's FAT partition (ie the one you see in windows).
You don't need to do anything other than put it there, it will be read on boot.
