Features

• DLP is a reflective technology and can deliver images with both high contrast and brightness (4200 lumens), creating a picture that is natural and life-like. It offers a native contrast-ratio of 300,000:1, a dynamic contrast-ratio of 2,000,000:1, and brightness of 4,200 lumens.
• Video and graphics produced by the latest DLP technology are sharper because the mirrors on the DLP chip are so close together that the gaps between pixels in an image are less noticeable. Spaced less than one micron apart, its mirrors create a crisp, detailed image.
• The inherent speed of DLP technology means that Optoma projector can output video and images at an astonishing rate of 120Hz for clear, seamless motion.

DuraCore Laser Light Source: A DuraCore Laser light source eliminates lamp and filter replacements for up to 30,000 hours of maintenance-free operation with consistent brightness, stunning color and exceptional image quality throughout the life of the projector. The GT2100HDR powers on nearly instantly with full brightness thanks to its DuraCore Laser light source, unlike lamp projectors that need warming up.

• Optoma DuraCore Laser projectors have a sealed, dust resistant optical engine to ensure excellent reliability.
• The DuraCore Laser light source maintains stable brightness (4,200 lumens) and color performance over the life of the projector without regressive decay like lamps.
• Up to 30,000 hours (Eco mode) or 20,000 hours (Bright mode) of light source life ensures many years of reliable operation without lamp replacements.

Short Throw Lens: With its short throw lens, the Optoma GT2100HDR can project an impressive 100" image from just over 3.5' away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease. The further away the projector is placed from the screen the projected image size increases and vertical offset also increases proportionally. To adjust the focus, turn the focus ring on top of the projector clockwise or counterclockwise until the image is sharp and legible (*this projector does not offer auto or manual zoom).

1080p Native Resolution: 1080p resolution gives you sharp and detailed images from HD content without downscaling or compression; perfect for watching Blu-ray movies, HD broadcasting and playing video games.
