Brief Introduction
Beta 2.5 |
The GT4000UHD 3D Laser DLP has 4000 ANSI lumens, a contrast ratio of 500000:1 and a UHD (4K2K) 3840 x 2160 resolution. The manufacturer specifies a laser lifetime of 30,000 hours, which equates to over 20.5 years of enjoyment at four hours per day. This projector has a projection ratio of only 0.25:1. For a 2 m wide image, the projector only needs to be 50 cm away from the screen. Furthermore, the projector can play 1080P and 4K as well as 3D without any problems, meaning that all currently available Blu-ray formats can be recognized by the projector.
