BenQ W20000 1080p, DLP, Home Theater Projector Overview
The BenQ W20000 is the flagship of the BenQ home theater projector lineup. It is a DLP projector using the Darkchip3 processor. BenQ refers to their iris system as a dual one. There is an iris that adjusts based on the preset mode (Cinema, Dynamic, Standard, User...), and a dynamic iris called Dynamic Black, which is the tradtional dynamic iris, constantly changing to match the scene and improve black levels in darker scenes.
BenQ W20000: First Comments
One real plus of the BenQ W20000, is that, for a DLP projector, it has a feature rarely found - vertical lens shift. This, combined with a longer throw zoom lens than many DLP projectors have, make the W20000 suitable for shelf mounting, instead of only having a ceiling mounting option. The fact that the zoom ratio is only 20% (1.2:1), does mean that depending on screen size, and room depth, some may not be able to place the projector on a rear shelf.
The W20000 projector is one of the brighter home theater projectors, offering significantly more lumens in its best, movie watching modes, than the typical 1080p projector. That doesn't mean, though that there aren't a few that are brighter still. In it's absolute brightest mode, it is again, above average, making it very suitable for larger screens, and for watching TV, especially sports when you don't want your room fully darkened.
