The OPTOMA's W515 proscene widescreen installation projector provides brilliant images and great dynamic contrast. Its base 1280 x 800 resolution clearly displays data and images at a variety of viewing distances, and its 10,000:1 dynamic contrast ratio helps dark images have more depth. The projector's throw ratio of 1.26 to 2.268:1 allows you to set it close to the screen without losing focus. The W515 also has an RCA composite video input, two VGA inputs, and two HDMI ports, one of which is MHL compatible for wired streaming from a compatible smart device.
