I have four 47" 1080p TVs and I want to mount them on my wall together in a square to show one picture. Ive seen it done before. I am looking for the equipment to do this. Can anyone help?
 
easy enough if you hook them up to a computer.

the televisions would be treated as monitors and you can move them around any which way you want.

if you want a source like a dvd player and some sort of magic box before the tvs then i'm not sure what products there are out there which can scale up the image to fit. scaling would look pretty bad quality wise.
