I want to use my 40" LCD tele to use my laptop instead of using the laptop directly itself. Ive got a VGA cable which works to display things, but it doesnt do any sound thru the tele. Also, I want to be able to use a wireless keyboard and wireless mouse instead of using the actual laptop. Its all to use from my sofa you see. Can you give me some advice on a setup and what exactly is needed. Thanks!
