They come with a mounted short throw projector (mostly Promethean re branded Sanyo equipment) which to be perfectly honest doesn't give a very bright/impressive picture in a standard daylight lit room.
They work absolutely perfectly, it's just a bit annoying that a great deal of them are still using serial connectors (for interaction with an electronic board pen for mouse input/on screen annotation in ActivStudio) so they seem a bit outdated. We use Promethean boards in our classrooms.
