Reduce the chance of shadows crossing your presentation with the Optoma X318ST 3300-Lumen XGA Short-Throw DLP Projector. Its short 0.62:1 throw ratio will allow you to place it roughly 11' from your screen and still produce a 300" image. Its 3300 lumens of brightness combined with its 20,000:1 dynamic contrast ratio will help images appear bright and clear in many settings, while its 1024 x 768 native resolution will help ensure that no detail is lost in large projections.

The X318ST has VGA, composite video, and two HDMI inputs to support a variety of devices; one HDMI input is MHL-compatible, allowing you to stream from your compatible mobile device while simultaneously powering your device via one cable. Its VGA output will let you daisy-chain the image to another projector or display while the analog audio input and output will do the same for your audio. The projector includes an IR remote control and a carrying case as an added convenience.
