i've seen instructions to rotate the screen by editing the /boot/cmdline.txt file. they don't work. i cannot rotate the screen.
i've seen instructions on changing the overscan boundaries by editing the /boot/config.txt file. they don't work either. i cannot change overscan behavior. when i open an app, part of the app window is off the screen. nothing i've tried will work.
anybody know how to fix this?
thanx, mike
