4K Lens Architecture
TK850I’s 4K optical system uses the highest quality glass for superior realism. The precision 10-element 8-group lens array allows greater light penetration for long-lasting 4K intensity.

Easy Upgrade for BenQ 4K 1080p Projectors
Upgrade to the 4K TK850i with a 10 percent vertical lens shift for a perfect fit in any room. Enjoy the convenience of a dynamic range of projection distances and heights.
