I've yet to see any TV/video monitor supply internet access to the other computers. I think you want the other computers to be able to send something to that display.
Why not any old HDTV and an AppleTV?
Moved to a new company, we have a meeting room that has no av. I need a suggestion to be able to add a TV/video monitor that I can get internet as well as access our in house computers. Any suggestions will be helpful, we are challenged in this area.
