Can anyone please give a hint what "Switch TV to correct input" in the HDMI CEC Setup options actually does? It doesn't seem to do anything. Unfortunately the info box on the left gives no clue (nor to any of the other HDMI options - just displays "Current CEC address: 2.0.0.0" for all of them).
I was hoping that the TV would switch to the correct HDMI input via CEC command when the T4 is powered up e.g. as it does when I power up my connected camera.
