First time post from a new RISC OS user.
I'm trying to get my Pi to boot into my TV's native resolution of 1366x768 @ 60Hz.
By default it goes to 1920x1080.
I've tried the Screen utility in iBoot and editing the CONFIG.TXT file and to be honest I don't know what I'm doing.
Any (simple) help would be greatly appreciated.
Thank-you in advance for any help
