No More Lamp Replacements Up to 20,000 hours of maintenance-free operation possible due to the laser light source. Actual hours may vary depending on usage conditions. Impressive Image Quality for Various Applications The latest Texas Instruments DLP™ engine featuring BrilliantColor™ technology offers great 15,000:1 contrast for high brightness images up to 5,000 lumens at Full-HD and WXGA native resolutions. Wide 1.7 ÃÃÂÃÂ Optical Zoom and H/V Lens Shift The wide 1.7 ÃÃÂÃÂ optical zoom, horizontal / vertical lens shift and keystone correction allow flexible setting in various locations. A Dustproof Design Supported by NEC''s Closed-loop Cooling System The projector has a dustproof design to prevent the staining of optical components from the ingress of dust and the deterioration of brightness and image quality. Heat within the dustproof units is exhausted from heat sinks, and the external air used for cooling does not directly contact the optical system, so the design offers both excellent dustproofing and cooling. Tilt-free and Portrait Installation Support The projector can be rotated freely (360°) to point up or down depending on the installation requirements and can be rotated (along with the screen if necessary) to a vertical alignment so that portrait content can be viewed without black bars on the sides when landscape mode is used.Compatible with Diverse Signal Sources Built-in HDBaseT Support Simplify your installations with HDBaseT, which is optimized for video applications and supports uncompressed Full HD digital video, audio, Ethernet, and various control signals. With only a single cable (up to 100 m) to run, infrastructure and labor costs are reduced, installations are significantly easier, and there is no cable clutter to manage.
