Verdict

The BenQ HT4550i is a premium 4K UHD home cinema projector featuring a long-lasting 4LED light source that delivers 3,200 ANSI lumens of brightness and a dynamic contrast ratio of 2,000,000:1. Its standout characteristics include 100% DCI-P3 color gamut coverage, HDR-PRO technology with support for HDR10+ and HLG, and 2D lens shift (vertical 0-60%, horizontal ±15%) for flexible installation. The main pros are its exceptional out-of-the-box color accuracy, impressive peak brightness suitable for moderately lit rooms, and low input lag (down to 8.7ms at 1080p/240Hz) for gaming. However, its primary cons include limited native contrast that can lead to raised black levels in dark scenes, potential rainbow artifacts common to single-chip DLP designs, and a basic 5W mono speaker that lacks stereo separation.
