The power input and a dual VGA-A/V input are located at the rear of the unit, and the included cables are long enough to give you flexibility in positioning the projector in tandem with a laptop or other input source. The bundled composite (RCA-type) A/V cable worked fine with our digital camera and DVD player, but we had to use a third-party cable to hook up the MPro120 to an and a for other tests. The MPro120 is a pass-through projector, meaning that it requires an external device for its video content; some pico projectors come equipped with built-in memory, media players, or card readers that enable them to work as stand-alone devices.

All in all, the 3M MPro120 is a solid performer with excellent image quality, outstanding battery life, and easy-to-use features.
