Brief Introduction
Beta 2.5 |
The Viewsonic LS901-4K 3D Laser DLP projector has 5500 ANSI lumens, a contrast ratio of 30000000:1, and a UHD (4K2K) 3840 x 2160 resolution. The manufacturer Viewsonic specifies the service life as 20,000 hours, which would be over 13.7 years if viewed for 4 hours a day. The horizontal and vertical keystone correction provides flexibility when setting up. The projector can illuminate images up to 787 cm wide thanks to its 5500 ANSI lumens. The projector can handle rooms with residual light with a smaller image width; we would recommend a maximum of 525 cm. Video signals in 1080P and 4K as well as 3D are no problem for the projector, which means that all currently available Blu-ray formats can be recognized by the projector.
