Radio channel screensaver?

[CarrotCruncher]

I am loving this new Zero and have just added my favourite radio stations. Is there a screensaver function when using the radio channels? It shows the radio bar etc permanently and that cannot be good for my screen long term.

A lot of the newer TV's have an option to turn the picture off and just have Audio.
On my Panasonic its >menu > Picture > Display > Off.
Check your TV picture menu and you may have a similar option.
