Hi, have been lurking on here for a good while so thanks for the info upto now

hooooooowever
I am in need of a solution:
I have a client/friend who wants a bit of an odd setup at his home/office, basically he has a PC with 2 x 32" LCD monitors attached and a further 32" screen (which he is yet to buy so can be altered) on the wall, he wants to be able to switch the image on his pc to the screen on the wall as well as being able to watch sky on that TV, not at the same time though, it also if its possible needs to be able to cope if he emplys another guy to work from his house to have another PC that can send its desktop etc to the wall mounted TV, again not at the same time.
Obviously he can have a VGA cable in a wall socket and manually alter the image to be duplicated onto the wall, however money isnt such an issue and he doesnt like technology, and wants things neat

so i was wondering if wireless video would be better or ip video?
Would the wall mounted TV need to have certain compatibility?
What equipment could i potentially need to do this?
Would i be better off getting a third party involved?

Steve
