[CeBIT 2012] At CeBIT 2012, Acer announced a new projector the K520 which uses laser instead of a regular projector lamp to display images. The K520 Hybrid LED Laser projector is said to deliver a dynamic contrast ratio of up to 100,000:1, 2000 lumens of brightness, 3D image output support, and features VGA, composite video/audio, and HDMI ports. It has a maximum output resolution of 1024 x 768 but supports 720p and 1080p input signals.
In case you’re wondering what the benefits of using laser over regular projector lamps are (no, you can’t cut through objects with these lasers), they last much longer than regular projector lamps. LED lasers can provide 20,000 hours of usage versus the 3,000 hours from regular projector lamps.
