The equipment of the Ricoh PJ WUL5A40ST projector includes 4500 ANSI lumens, a contrast of 5000000:1 with a WUXGA 1920 x 1200 display. The laser technology ensures a specified light source lifespan of up to 20000 hours. With four hours of daily operation, this corresponds to a period of 13.7 years. Should a perpendicular setup to the screen not be possible, the integrated keystone correction (horizontal and vertical) helps to realign the image into a perfect rectangle. With its short projection distance, the short-throw model excels in smaller rooms, requiring only 88 cm of wall distance for an image width of 2 meters. A look at the light output reveals: The 4500 ANSI lumens are sufficient to illuminate an image width of up to 682 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 455 cm. In terms of video signals, the device processes resolutions up to Full HD 1080P and 4K. Furthermore, the model supports 360° projections for highly flexible deployment scenarios. Connectivity for fixed installations is rounded off by an RJ45 port for remote maintenance and an HDBaseT interface, which transmits bundled video, audio, and control data over long cable runs.
