The specifications of the Hewlett Packard MC475 include 250 ANSI lumens and a display resolution of HDTV 1920 x 1080. The LED unit of this model is rated for up to 30000 hours of runtime. Daily use of 4 hours makes an operational lifespan of over 20.5 years possible. 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. Looking at practical performance, up to 161 cm can be illuminated with 250 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 107 cm. Regarding signal processing, the model is compatible with incoming 1080P content. For wireless audio output, the projector also supports Bluetooth, making it easy to quickly connect external soundbars. Thanks to support for Miracast and Airplay, screen content can also be cast wirelessly from a smartphone, tablet, or PC to the screen.
