help .. wireless transmitter options

Hi,

 Im a little lost since ive never attempted this before.

I watch movies / work from my laptop.

I have a Projector connected to the laptop (just basic SVGA or Svideo)  for big screen viewing and the audio is through a hi fi system from the pc.

Now I have cables running all around, VGA cable from laptop to projector and minijack cable from laptop to hi fi for audio + all the additional power cables. Its all too cluttered.

Now Im looking at buying a wireless transmitter and reciever for both audio and video... ideally i connect my transmitter to my laptop and i can have 2 recievers one that I can connect to my projector for video and another i can connect to my hi fi for audio...

Any help in choosing/setting up one/other options is highly appreciated!
