The projector EH R4000 by Epson operates as a Laser-LCD device with 1200 ANSI lumens, a HDTV 1920 x 1080 resolution and a contrast of 1000000:1. The manufacturer specifies a runtime of 5000 hours for this projector's lamp, achieving a lifespan of 6.8 years when used for 2 hours a day. In terms of image alignment, the model offers an optical lens shift function, allowing the image to be shifted without quality loss. The exact adjustment leeway can be calculated in the Lens Shift Calculator. A look at the light output reveals: The 1200 ANSI lumens are sufficient to illuminate an image width of up to 352 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 235 cm. Regarding signal processing, the model is compatible with incoming 1080P content. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. With a value of only 21 decibels, the noise level during operation remains pleasantly in the background. This model dates back to 2010 and is no longer part of Epson's current product range.
