Most home projectors can’t give a crisp image when the scene turns overly dark or overly bright. That’s because they have a limited contrast ratio. The BenQ W5000 & W20000 is different. Built to deliver ultra-high contrast, this projector allows you to see visuals on-screen just as you would see them in real life. Because connoisseurs know the difference, this projector is built to world-class specifications.
Because Enjoyment Matters.
The BenQ W5000 & W20000 with Senseye technology brings you the best picture quality in 1080p Full HD, ultra-high contrast ratio, smooth video stream performance and HQV (Hollywood Quality Video) that renders standard definition material in Full HD-like video quality, and much more.
Contrast Enhancement
A Unique, Two-Step Image Enhancement Process: BenQ’s Dual Iris Technology.
When you are watching a really great movie, there are certain times when high contrast ratio can make all the difference, places like: the darkest reaches of outer-space, the skies high above the battlefield, a haunted house or inside an Egyptian pyramid. With high contrast ratio, everything is clear. You can see all of the details. Without it, you’re just in the dark.
In order to provide you with the most detailed image possible, the BenQ W20000 enhances image contrast via its Dual Iris technology so that bright images become brighter and dark images become darker -- both with more detail and refined gradients between them. High contrast ratio means a higher level of viewing enjoyment. Here’s how dual iris technology works:

Step One: Advanced Continuous Electronic Iris – An Electronic Iris with Different Preset Modes.
For optimal viewing, the BenQ W20000 comes with 4 viewing modes (Cinema, Dynamic, Standard, and Photo) that you can select, plus 3 memory slots that you can calibrate to your own preferred settings.
The advanced continuous electronic iris works like your own eye. It widens and narrows, letting out as much light as necessary to match the selected contrast range.
Step Two: DynamicBlack™
Together with Texas Instruments’ DynamicBlack™, BenQ contrast technology provides a second level of Iris control that enhances contrast based on the exact image being shown. Darkened scenes? No problem. DynamicBlack™ digitally examines source video to determine the appropriate iris aperture for the level of light present in a given scene and open and close the projector iris accordingly. When it’s darker, the iris closes to boost contrast. When it’s lighter, the iris will open. So, you’ll see everything.
