As mentioned, the ViewSonic LS740HD is a full HD 1080p (1920x1080) resolution commercial projector made for bright environments with its 5,000 lumen claim. (It measured slightly shy of its claim at 4,783 ANSI lumens, well within the accepted tolerance.) At just 11.3 x 5.0 x 8.5 inches (WHD) and 6.6 lbs, it is compact and can easily be transported from room to room, as well as installed permanently for a variety of applications where ambient light is a concern. This is a DLP projector with third-generation laser phosphor technology, with a light engine lifespan of up to 30,000 hours in Eco mode.The LS740HD's lens is a 1.3x manual zoom lens with manual focus, located on the front left of the projector and controlled via its focus and zoom rings. The focus ring is a ribbed ring around the front of the lens, and the zoom ring is accessed in a recessed area on top. The front IR sensor is to the left of the lens. On top of the projector, at the back, is the control panel, and the top IR sensor. The air intake vents are on either side of the LS740HD, with the intake on the left, and the exhaust on the right. The back of the projector houses the inputs and connectors. If you opt for an inverted ceiling mount, there is a recess on the bottom where you can secure the supplied power brick with a cable tie.
