    I'm having a major issue with my Macbook Air HDMI adapter, basically I connect it up to my LCD TV via the HDMI cable and all I can get on the TV is the background screen.

    My actual desktop doesn't show up, if I try and play a film from my Macbook Air it doesn't show up on the TV either. Just the Background screen

    Any advice?

    You have to designate the TV as the primary monitor. In the System Preferences / Display screen, drag the little menu bar from the MBA screen to the TV.

    Aw thank you :) Do I have to do this everytime I connect the HDMI to the TV or just the once for the setup?


    I guess I should also ask while I'm here, I've also tried to just setup my Macbook Air to my Onkyo TX-SR508 receiver for listening to my lossless audio but I'm having the same issue via the HDMI cable. I just get the sound on the laptop when I press play


    Officially sorted :) Thanks for your help mate!
