With the addition of this video module on the back of the projector, the Compaq MP1600 is immediately transformed into a powerful video interface, allowing presenters to easily toggle between their computer and video (VCR, DVD player or camcorder) without ever having to interrupt the presentation to set up a separate video presentation. Small enough to fit in your hand, the module easily snaps on and off the back of the Compaq MP1600. It also includes an indicator light, and is compatible with both video and S-video.
