The OPTOMA's EH412 4500-lumen Full HD DLP projector provides brilliant images and strong dynamic contrast. Its basic 1920 x 1080 resolution clearly displays data and images at various viewing distances, and its 50,000:1 dynamic contrast ratio aids in the enhancement of clarity in dark images. The projector's throw ratio of 1.12 to 1.47:1 allows it to be placed quite close to the screen without losing focus. It has a VGA port as well as two HDMI inputs, one of which is MHL-compliant for wired streaming from a compatible smart device. HDMI streaming adapters can be powered via a USB port.
