    Hiya guys, bit of an annoying problem with my new MBA ultimate - I have a presentation to do on tuesday, and when I went in to test my setup on the projectors in uni, I hooked up my MBA to the projector and my background reset to the default purple space one? Also seems to happen to my 24" samsung syncmaster...

    I'm literally mirroring my desktop onto the projector rather than extending - how can I set it to stay to my chosen desktop across all monitors/displays etc?

    Thanks in advance,

    You have to assign desktops on a per-monitor basis. When you connect a monitor that hasn't been connected before, it defaults to that desktop BG.
