The Graphics 6400 is a LCD projector by Barco, whose specifications list 3000 ANSI lumens, a contrast of 450:1 and a XGA 1024 x 768 resolution. The manufacturer lists the lamp life at 1000 hours. In terms of image alignment, the model offers an optical lens shift function, allowing the image to be shifted on the projection surface without any loss of quality. A major advantage for professional installations is the ability to use interchangeable lenses, allowing the projector to adapt to highly varied projection distances. Which optic is required for a specific case can easily be calculated via the Projector Calculator. A look at the light output reveals: The 3000 ANSI lumens are sufficient to illuminate an image width of up to 477 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 318 cm. This is a discontinued model that is no longer officially distributed by Barco. Note: According to our information, replacement lamps (original or generic) are no longer available for this projector.
