ive never heard of that
maybe possible on some top of the line tvs and they would say that in the instructions but normal tvs, no you cant you would need something to act as a media centre, for example i can stream from my computer to my ps3 and then watch on my tv but there is no way to connect direct to the tv
can you not just connect your pc to the tv via a vga or hdmi cable? then you wouldnt need to stream anything
