Brief Introduction
Beta 2.5 |
The Optoma TX7855 3D BrilliantColor DLP projector has 4800 Ansi lumens, a contrast of 2000:1 and an XGA 1024 x 768 resolution. The integrated lens shift gives you freedom when positioning the projector. The projector can illuminate an image width of up to 603 cm thanks to its 4800 Ansi lumens. The projector can create rooms with residual light with a smaller image width, we recommend a maximum of 402 cm. It is also Full HD 1080P compatible. On the market since 2010, the model is no longer offered by the manufacturer Optoma, but is still very popular in our projector database.
