The BenQ W4100i is a flagship 4K UHD home theater projector built around a maintenance-free Multi-LED light source rated for up to 30,000 hours. It claims 3200 ANSI Lumens, full DCI-P3 color coverage, HDR10+ and 3D, plus HDMI 2.1 with 4K at 120Hz for gaming. Google-certified Android TV is built in, and extensive horizontal and vertical lens shift with a 1.3x zoom and 2D keystone suits fixed installations. Against lamp-based 4K projectors it trades replacement lamps for LED longevity and higher color volume, but it is a large, installation-oriented unit rather than a portable one.
