The Sharp PG-D2870W 3D Ready projector combines high brightness (3000 Lumens) and WXGA native resolution with the convenience of short-throw projection design. This makes the PG-D2870W a wise choice for classroom and meeting room applications. This short-throw design is ideal for interactive presentations and simplifies the projector placement in classrooms, meeting rooms and other venues with limited space. An optional wall mount bracket (AN-STWM20) is also available to simplify installation. Incorporating DLP Link technology, the projector is compatible with 3D field sequential content and active shutter 3D glasses (not included) that support the DLP Link system, so you can captivate audiences with breathtaking 3D imagery. The PG-D2870W offers 3D support with both 60 Hz and 120 Hz WXGA (1280 x 800 and 1280 x 720), XGA (1024 x 768) and SVGA (800 x 600) sources. (When not being used for 3D projection, these models offer full compatibility with traditional "2D" content). In addition to incorporating the latest BrilliantColor™ DLP® technology with DLP Link™ (for high quality 3D projection from a single projector), the PG-D2870W offers a 7 Watt audio system, RJ-45 network connector, built-in closed caption decoder and sealed DLP chip with filter-free design. Built in an ISO 14001 certified factory, with standby power consumption as low as 0.32W and an estimated lamp life of up to 5,000 hours (Eco+Quiet: On), this slim and lightweight RoHS compatible projector is exceptionally environmentally friendly!
