The OPTOMA's S341 3500 lumen SVGA DLP projector provides brilliant images with a great contrast ratio. At varied viewing distances, its original 800 x 600 resolution will clearly display data and most images. With a throw ratio of 1.94 to 2.16:1, user may set the projector far away from the screen without losing focus. It also supports a wide range of devices with HDMI, VGA, and composite video inputs. The VGA output allows user to daisy chain the image to another projector or display, and the analogue audio input and output allow to do the same with the sound.
