i think the bestway is powerline you can get either wireless or wired variants but your tv would need a wireless adapter if it isnt wifi enabled and i have no idea how to get wireless adapaters for tvs
so best option would be a wired powerline set up which means some wires but not all round your house
if you go to virgin media.com tab above and go into the pc and then home networking theres a few powerline adapters that virgin recomends but you can go on ebay and get them cheaper but your home wiring needs to be decent condition for decent speeds thats the only option i can think of for not running wires all over your house hope this helps its also recomended you plug powerline directly into a wall socket and not an adapter for the best speeds
I want it to view my pc screen so I can watch videos I make and show photo and stuff like that... suppose it would be like another monitor.... I want to be able to access my pc files etc... hope that makes sense.
sorry I meant to say HDMI cable not HDTV cable... but the HDMI is too short to run from pc to tv
You can forget about this option if the TV is not an Internet-ready HDTV. You'd need an extra box to provide internet access that you then plug into your HDMI port. There are many available like Roku or Apple TV:
Even if it was Internet-Ready or you use a box like the Roku that still wouldn't get the laptop display onto the TV screen. He could upload the pictures to a site or a flash drive, browse web sites and pictures from the TV and stream movies from Netflix but where is his laptop screen on the web? This isn't exactly what the OP asked for.
