The hardware properties of the MP 7740i manufactured by 3M include 1200 ANSI lumens, a XGA 1024 x 768 resolution and a contrast value of 400:1. The manufacturer specifies a runtime of 2000 hours for this projector's lamp. A look at the light output reveals: The 1200 ANSI lumens are sufficient to illuminate an image width of up to 302 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 201 cm. This model dates back to 2002 and is no longer part of 3M's current product range.
