I wanted to ask you something

when I put the list of external devices, hdmi ,scart ....

I only use the tv and the hdmi 1, and wanted to know if the list of external devices I can remove the rest, and when I press the button only appears on the list the tv and the hdmi 1 and already, so no I have to go by pressing the button to cycle external input

I have tv 405605H/12.

Thanks
