I have connected my macbook pro with the TV. When it's connected, the wallpaper changes to mac's default wallpaper (the one with the space). I can change it in the mac's screen (although I have to do it manually every time I connect it to the TV) but it doesn't change at the TV.

Is there a way to have the wallpaper I want instead of the default one at the connected TV's background?

Thanx in advance,
