The projector TXF-4200 by Wolf Cinema utilizes DILA technology and, according to the spec sheet, achieves 3300 ANSI lumens and a resolution of UHD (4K+2K) 4096 x 2160. The laser technology ensures a specified light source lifespan of up to 20000 hours – equivalent to a usable life of 13.7 years at 4 hours a day. A look at the light output reveals: The 3300 ANSI lumens are sufficient to illuminate an image width of up to 1016 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 677 cm. For media input, video signals up to 1080P and 4K as well as 3D are supported, meaning standard Blu-ray formats are processed effortlessly.
