I have just tried to connect my Mac book pro to an LG Plasma TV via an iWires Mini DisplayPort to HDMI cable. All I get on my TV is the Mac wallpaper and nothing else. I am missing something really silly, could anyone help please.

Hi there. I also bought an iWires mini Display port to HDMI cable and have an LG LED/LCD TV. I plugged it in to my MB Pro and followed the very small writing that came in the package and got both audio and video going. You need to change the audio settings from within System Preferences on your Mac to select your TV as the audio output.
My concern is the data latency - do you experience a delay between moving your mouse on the MBPro and the TV displaying the movement? It is only a fraction of a second, but certainly enough to be annoying, especially in a cable as expensive as the iWire.
