Product Description

The PowerLite 1781W is designed for presenters on the move. The slim 4-pound chassis fits in a laptop bag, and a carrying case is included. The 3LCD, 3-chip light engine produces equal 3,200-lumen color and white brightness, so slides and video stay vivid in rooms where the lights stay on, and a 10,000:1 contrast ratio holds detail in darker areas. Native WXGA 1280 x 800 resolution suits widescreen 16:10 presentation content.

The included LAN module enables wireless connectivity so a laptop, tablet, or smartphone can project without plugging in, and the unit reads Chromecast via HDMI, Roku, and MHL streaming sources. A single MHL-enabled HDMI input plus VGA and composite video cover wired sources, with USB video support from Windows and Mac. Auto horizontal and vertical keystone correction and Screen Fit square the image even off-center. For a Full HD 1080p version, compare the PowerLite 1795F, or for the lower-brightness model see the PowerLite 1780W in the same family. Browse the full Epson projector lineup at Creation Networks.
