The technical data of the InFocus LP640 includes 2200 ANSI lumens, a contrast of 400:1 as well as a XGA 1024 x 768 display. The manufacturer rates the durability of the included lamp at 2000 hours. To ensure a rectangular image even with asymmetrical placement, the projector includes digital keystone correction for both the horizontal and vertical axes. A look at the light output reveals: The 2200 ANSI lumens are sufficient to illuminate an image width of up to 408 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 272 cm. For media input, video signals up to 1080P are supported. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. The projector was released in 2004 and is officially no longer distributed by InFocus.

I have 3 identical ones, one in the room and basement and one in a video box. I think the best thing is the optional accessories, a special cable and remote control with which you can emulate a laptop mouse with a direct connection. I would classify the picture and brightness as average at best, all in all a solid XGA projector that is getting old.
