A projector from DBPOWER is the RD-821, whose LED-LCD model delivers 420 ANSI lumens, a resolution of HDTV 1280 x 720 and a contrast of 3000:1. Thanks to LED technology, the projector is rated for a lifespan of up to 55000 hours, covering an estimated 37.7 years based on a 4-hour daily runtime. The image geometry can be adjusted via the built-in keystone correction so that a clean, rectangular display is achieved even with non-ideal placement. To ensure objective comparability, an approximate ANSI lumen value was calculated based on the lumen specifications. Regarding projection size, the value of 420 ANSI lumens allows for an image width of up to 208 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 139 cm. Regarding signal processing, the model is compatible with incoming 1080P content. Since the projector supports Miracast and Airplay screen mirroring, video signals can also be streamed wirelessly from the end device.
