Is this what the port looks like? If yes then you need a minidisplay port to HDMI. Apple doesn't make on so you will need to get a 3rd party one.

either 3.5mm stereo to 3.5 stereo or 3.5 mm stereo to RCA stereo for the audio.

Ye i do have a minidisplay port. can u recommend a few 3rd party cables?
The TV came with a stereo cable, will that be sufficient?
