This projector is named NP4001, originates from Nec, and its data sheet shows 4500 ANSI lumens, a contrast of 2500:1 and a resolution of WXGA 1280 x 768. The manufacturer specifies a runtime of 2000 hours for this projector's lamp. For distortion-free image alignment, the projector offers both a lens shift function and keystone correction, granting significant leeway during mounting. Thanks to the interchangeable lens system, the device can be equipped with optional lenses to react flexibly to different room sizes. Exact values for specific rooms are provided by the Projection Calculator. Regarding projection size, the value of 4500 ANSI lumens allows for an image width of up to 682 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 455 cm. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. This model dates back to 2007 and is no longer part of Nec's current product range.
