The LV-7275 connects to a variety of devices including laptop and desktop computers, DVD players, digital cameras, camcorders, and VCRs. HDMI devices are connectable using an HDMI to DVI adapter*. Many desktop PCs cannot be connected to both a projector and monitor at the same time. The LV-7275's Monitor Out terminal allows for an external monitor to be connected to the projector- a practical feature in settings where the projector is hooked up to a desktop computer. In addition, the projectors network capabilities allow you to control projector's from a central location.
