BenQ W4000i

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 analyses each segment’s brightness and adjusts gamma independently for greater dark and bright detail definition and enriched 4K image depth.

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

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

Colours as Directors Envisioned
Only true colours evoke feelings of sorrow, joy, romance and thrills. With professionally tuned by ISF and THX-certified engineers, each W4000i is backed up by factory calibration reports to ensure reproduction of authentic Cinematiccolour super-wide 100% DCI-P3 and 100% Rec.709 colour space.

Out-of-Box colour Accuracy
Individual factory calibration reports assure 100% Rec.709 Delta E<3 and total grayscale tracking within Delta E<2 with optimised Rec.709 colour table for true Hollywood colours.

Exclusive colour Temperature Tuning
For ultimate colour accuracy, BenQ high-end cinema projectors provide advanced colour 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 colours.

Filmmaker Mode
Filmmaker Mode preserves motion cadence, cinematic colour, 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.
