I am looking for a slick way to have a selectable display of either TV or PC output to multipe 24" wall mounted displays in a dental office. I have read a little about HDMI however it looks like this technology is not yet widely available. We would like to have a 24" monitor in each of several operatories with the slickest possible installation. Is there a way to have a single PC which drives multiple monitors (multiple video cards, etc) without the monitors having to display the same content? Ideally we would like to be able to select the displayed content from each operatory without having to have a PC in each operatory. I know this idea may be a little far fetched, but we want to push the envelope.
