BenQ LW820ST VGA 3600 Lumens DLP Projector
The BenQ LW820ST PROJECTOR From BenQ. BenQ LW820ST PROJECTOR uses the powerful BenQ BlueCore Laser Technology for Pure Color. Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 3,600 lumens. Comprising over two million micromirrors that reflect pure light through the colour wheel, the BenQ LW820ST PROJECTOR chip is hermetically sealed to resist heat for over 100,000 hours without degradation. This BenQ LW820ST PROJECTOR has an IP5X dustproof mechanism which reduces maintenance costs. It uses DLP Single 0.65" WXGA projection system and deliver up to a resolution of 1280 x 800 pixels at a 16:10 ratio. It has 1.07 Billion Colors and the contrast ratio is 3,000,000:1. The lamp has a life of 20000Hrs. It features 10Wx1 Built-in Speaker. BenQ LW820ST PROJECTOR supports resolution VGA(640 x 480) to WUXGA_RB(1920 x 1200). HDTV compatible with 480i, 480p, 576i, 576p, 720p, 1080i, 1080p resolution.
