Expand Your Vision with All-New Home Projectors

Experience innovative cinematic visuals and immersive entertainment with new BenQ home projectors. Bask in authentic colors and bright and dark details supported by CinematicColor and HDR-PRO technologies in your home cinema for the most genuine, eye-popping experiences.

Relish the Cinematic Details

In pursuit of perfect picture quality, BenQ HDR-PRO technology employs Optimal HDR Tone Mapping, Leading Local Contrast Enhancer, and Dynamic BlackTM to overcome brightness constraints and optimize contrast effects for authentic HDR performance.


HDR-PRO for Perfect Details in Dark and Bright Areas

Leading Local Contrast Enhancement

Applying local contrast enhancer algorithm to divide images into 1,000+ zones, Local Contrast Enhancer analyzes each segment’s brightness and adjusts gamma independently for greater dark and bright detail definition and enriched 4K image depth.

Dynamic Black Technology

With Dynamic Black technology, BenQ cinema-optimized Enhanced Tone Mapping increases contrast out of accurate calculation and precise projection to preserve details in dark areas of projected images.

HDR Video Optimization Frame by Frame

New HDR10+ technology adds dynamic metadata to HDR10 source files, which is used to adjust and optimize each frame of the HDR video to enhance details in both bright and dark areas of HDR10+ content.

Colors as Directors Envisioned

Only true colors evoke feelings of sorrow, joy, romance, and thrills. With professionally tuned by ISF and THX-certified engineers, each TH4550i is backed up by factory calibration reports to ensure reproduction of authentic CinematicColor super-wide 100% DCI-P3 and 100% Rec.709 color space.

Out-of-Box Color Accuracy

Individual factory calibration reports assure 100% Rec.709 Delta E<3 and total grayscale tracking within Delta E<2 with optimized Rec.709 color table for true Hollywood colors.

Exclusive Color Temperature Tuning

For ultimate color accuracy, BenQ high-end cinema projectors provide advanced color temperature tuning with 11 leading levels of white balance controls between high to low brightness, enabling content fanatics to adjust the most accurate mid-tone colors.

Filmmaker Mode

Filmmaker Mode preserves motion cadence, cinematic color, dynamic range, and brightness that directors intended for the big screen. BenQ smart home projectors support the filmmakers’ desire for home viewers to relive majestic scenes and tender moments the way they were meant to be seen.

24P Playback Support

Most movies are shot at 24 frames per second (fps). In order to display movies exactly as directors intended, HT4550i supports 24P playback of high-definition sources at 24 fps without judder in HDR mode to preserve the purity of the original image.

Long Lasting Color You Can Count On
