The HP xb31 is a lightweight, powerful projector that projects high-quality images for presentations that impress. The xb31 weighs 3.5lbs and has 1200 ANSI Lumens, bright enough for a large conference room, but just as comfortable in a small meeting room. The xb31 projects your images with XGA resolution (1024 x 768), for a sharp, crisp and accurate picture. The wireless remote controller with USB mouse function and a laser pointer give you the freedom to move around the room during your presentation. xb31 easily adapts from one venue to another and is equipped with built-in, full-screen NTSC/PAL/SECAM video compatibility, and compatibility with S-video, composite component, and HDTV terminals.
