The AI technology intelligently analyzes frame composition to optimize visual details in real time, ensuring the best possible picture quality across all content, including streaming services like Netflix, Disney+, and Prime Video.

HDR-PRO Technology for Perfect Balance
Experience ideal HDR performance with BenQ's HDR-PRO technology, featuring an advanced "multi-stage" light control technique. This technology enhances authentic HDR viewing without compromising image quality, effectively balancing brightness and optimizing contrast for superbly detailed visuals. The projector supports HDR10, HDR10+, and HLG formats with dynamic tone mapping that analyzes each frame in real time, dynamically adjusting tone curves to preserve both bright highlights and deep shadow details.

CinematicColor with 100% DCI-P3 Coverage
Faithfully reproduce images the way the artist intended. The W4100i delivers CinematicColor super-wide 100% DCI-P3 and 100% Rec.709 color space with precise colors to perfectly preserve what directors envisioned. Individual factory calibration reports ensure Delta E<2 out-of-box color accuracy for true Hollywood colors. The projector includes exclusive 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.

4LED Light Source Technology
The projector utilizes advanced 4LED light source technology providing 3200 ANSI lumens brightness with exceptional color reproduction. The LED light source can last around 20,000-30,000 hours with no need to be changed during the lifetime of the projector mostly. Multiple light source modes are available: Normal (full brightness), ECO (extended life with lower brightness), Low Dynamic (automatic black level adjustment for enhanced contrast with smooth transitions), and High Dynamic (quick black level changes for obvious brightness transitions).

Advanced Contrast Enhancement Technologies
The W4100i incorporates multiple contrast enhancement technologies for superior image quality. Global Contrast Enhancer analyzes the entire frame and enhances contrast across dark, mid, and bright areas with custom-tailored curves. Local Contrast Enhancer refines contrast in over 1000 independent regions per frame, ensuring tailored enhancement for each area without compromise. Dynamic Black automatically adjusts projection light output by detecting imagery, ensuring optimal contrast and life-like images.

CinemaMaster Video Processing
The projector includes advanced CinemaMaster processing with multiple enhancement features. Color Enhancer (0-18 levels) allows fine-tuning of color saturation with larger flexibility, modulating complex color algorithms to flawlessly render saturated colors and fine gradients. Pixel Enhancer 4K (0-20 levels) uses super-resolution technology to radically enhance Full HD content in terms of colors, contrast, and textures. Motion Enhancer 4K provides multiple levels (Off/Low/Middle/High) of picture smoothness enhancement through motion estimation and compensation. Built-in Noise Reduction (Off/Low/Middle/High) enhances compressed streaming content quality.

Filmmaker Mode and 24P True Cinema
Filmmaker Mode preserves motion cadence, cinematic color, dynamic range, and brightness that directors intended for the big screen. When Filmmaker Mode is selected, 24P True Cinema is automatically enabled. The projector supports 24P playback of high-definition sources at 24 fps without judder in HDR mode to preserve the purity of the original image, displaying movies exactly as directors intended with the authentic cinematic experience.
