As a projector for the Standard-Portabel sector, the Viewsonic PX748-4K is equipped with 4000 ANSI lumens, a UHD (4K2K) 3840 x 2160 resolution and a contrast of 12000:1. The manufacturer specifies a runtime of 4000 hours for this projector's lamp, which amounts to roughly 5.5 years at 2 hours of daily use. 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 643 cm can be illuminated with 4000 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 429 cm. Regarding signal processing, the model is compatible with incoming 1080P content and 4K. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. The projector was released in 2021 and is officially no longer distributed by Viewsonic.
