Verdict

The BenQ W4100i is a high-end 4K HDR home cinema projector featuring 2,500 ANSI lumens of brightness and 100% DCI-P3 color coverage via CinematicColor technology. It excels with a 4LED light source for 30,000-hour longevity, HDR-PRO with Local Contrast Enhancement, and an SSI Dynamic Black feature for deep 600,000:1 contrast. While it offers superior color accuracy and 2D lens shift for easy installation, its main drawbacks include a lack of built-in Netflix on the integrated Android TV dongle and a higher price point compared to entry-level 4K models.
