I'm setting up a Mac Mini as a media server in our living room, hooked up to our flatscreen TV and home stereo. I've just purchased a gorgeous diNovo Edge, bluetooth keyboard to control it. I'm psyched. The thing is that my wife would really like to also be able to sit down at the small office desk, at the back of our living room, and use her 17" display with the Mini as well, for times when she doesn't want to power up the big LCD or when somebody else is watching TV. The exact run would be about 40 feet. I've already got a CAT5 cable that takes that route. What might be the least expensive way to get signal to that 17" monitor, across the room? The Mini is the last generation, with just one video output.
