Brief Introduction
Beta 2.5 |
The Promethean PRM 20A short-throw LCD projector has 2000 Ansi lumens, a contrast of 500:1 and a WXGA 1280 x 800 resolution. As it is a short-throw projector, the projector can be placed very close to the wall. For a 2 m wide image, the projector needs to be just 100 cm away from the screen. On the market since 2010, the model is no longer offered by the manufacturer Promethean.
