How do you differentiate between displaying to a TV or projector for a
presentation, or using an external monitor as your primary display
when you're preparing, or watching a video on your own?
Good question: As I mentioned in the other message, this is tricky, and I don't know the right answer. The xrandr extension provides lots of information about a video output, and it's probably possible to guess from that if we're dealing with a projector or TV. I won't be 100% correct, but it may work in many cases.
Also, future versions of X/Gnome wil automatically offer a configuration box as soon as you plug in a monitor. We can consider asking the user once at that point if this is a projector. The UI for doing this would have to be very well thought, but I guess this could work if done properly.
