Got a new TV with several HDMI inputs.
My Sat setup works great, and when turning on the receiver the TV stays off (hdmi cec disabled)
How ever,,when it comes to the pi.
the pi is set that it reboots every sunday morning, and till my surprice the tv turnes on.
noticing also that the whole screen was not centered ,but shifted to the left
after tweaking the config.txt in the firmware directory i managed to fix some small isues
but the tv keeps turning on and it still is not centerered
so, could some take a look at it to see what i messed up on it?
