The OPTOMA's W341 3600 lumen WXGA DLP projector provides bright, clean images. In many circumstances, its 3600 lumens of brightness will overpower ambient light, while its 22,000:1 contrast ratio and native resolution of WXGA (1280 x 800) will ensure that detail is visible. It offers a throw ratio of 1.54 to 1.7:1, allowing you to set the projector far away from the screen without losing focus. The W341 supports a wide range of devices with VGA, composite, and two HDMI inputs. The VGA output allows user to daisy chain the image to another projector or display, and the analogue audio input and output allow you to do the same with the audio.
