The Vivitek DW770USTi is a 3D-Laser-DLP projector offering 3500 ANSI lumens, a contrast of 14000:1 and a resolution of WXGA 1280 x 800. The manufacturer lists the lamp life at 6000 hours – mathematically sufficient for 8.2 years based on two hours of use per day. Thanks to the combination of optical lens shift and digital keystone correction, the projected image's position can be adjusted very flexibly. The Projector Calculator helps find the optimal installation dimensions. The short-throw capabilities allow for large images at a short projection distance. According to specifications, a 2-meter wide image requires a distance of only 70 cm. A look at the light output reveals: The 3500 ANSI lumens are sufficient to illuminate an image width of up to 601 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 401 cm. For media input, video signals up to 1080P and 4K are supported. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. This model dates back to 2019 and is no longer part of Vivitek's current product range.
