The high definition WL639U LCD projector is a WXGA projector for business, education, or house of worship. It's extra bright at 3500 ANSI lumens for your large multipurpose, conference, and meeting rooms. This presentation projector displays 16:9 high-definition digital video content in a widescreen 16:9 format. Using the latest 3LCD technology, this LCD projector locks in intricate details and real-life colors with every presentation. sRGB technology ensures true color reproduction by matching hue variations in the color spectrum. With Color Enhancer and 3D Color Uniformity this WXGA projector can give you uniform hues across your entire screen. Color Wall Correction enables you to maintain those true colors even when projecting on colored walls. And its 600:1 contrast rating will give you clear images even in large spaces or rooms with lots of light. The integrated LAN interface and PJLink with ProjectorView software option enable you to connect the WL639U to your network for remote management from your PC. Then secure it with the anti-theft anchor and the user-selectable password to lock out menu functions and prevent unauthorized tampering with projector settings. Digital keystone correction (horizontal and vertical) allows you to set up in the most challenging presentation environments. For permanent installs, its side-loading lamp design gives you convenient access for lamp changes.
