Verdict
The BenQ HT4550i is bright, low-lag and rich in picture modes, but its green-tinted brightest mode and low native contrast hold back the picture.

Verdict
The BenQ HT4550i is a bright, factory-calibrated 4K projector with excellent lens shift, best used in a dark room, though its built-in sound is weak.

What customers don't like about BenQ HT4550i

  • Native contrast and black levels are considered limited for a high-end home theater projector
  • Built-in 5W mono speaker lacks depth and power compared to external systems
  • Fan noise can be noticeable when running at full brightness

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.
