The OPTOMA's W512 5000 lumens WXGA DLP projector provides brilliant images and strong dynamic contrast. Its base 1280 x 800 resolution clearly displays data and images at a variety of viewing distances, and its 15,000:1 dynamic contrast ratio helps dark images have more depth. The projector's 1.48 to 2.35:1 throw ratio allows to set it close to the screen without losing focus, and wireless screen mirroring is possible with HDCast Pro connectivity on Android, Mac OS, and Windows devices. The LAN display can accommodate up to four computers at once, while the USB display can reflect Android and iOS devices. HDMI, VGA, and analogue inputs are all available for convenient connection to current and legacy video sources.
