BenQ W4100i Review | 85 Data compared

The BenQ W4100i (referred to as the X4100i in the technical data) is a high-performance 4K DLP home cinema projector that utilizes XPR-shifting technology paired with a durable 4LED light source, delivering 1,950 lumens in SDR and 2,080 lumens in calibrated HDR mode. A standout feature highlighted in the review is its exceptional out-of-the-box color precision, as each individual unit comes factory-calibrated alongside an included calibration report. The projector excels with an integrated local contrast enhancer that divides images into over 1,000 zones to optimize gamma, fully automated self-color-calibration sensors, and a smooth Android TV interface supporting major platforms like Netflix and Disney+. Furthermore, it incorporates advanced dynamic tone mapping, which dramatically improves static HDR10 and HLG projection framing, alongside native, stutter-free 3D playback support. The reviewer identifies several major pros, including a comprehensive 6-axis color management system, near-silent operation at 30 decibels, dynamic contrast expansion up to 3500:1, and a long light source lifespan reaching up to 30,000 hours in high mode. However, significant cons are also noted. Most notably, activating the Wide Color Gamut (WCG) filter to achieve...

On the positive side, the projector is praised for its exceptional HDR performance powered by dynamic tone mapping, precise factory color calibration, reliable automatic LED color adjustment, and robust connectivity. It includes an Android TV QS02 dongle for seamless smart TV app integration, features a short 10-second cool-down phase, and handles 1080p content beautifully via artifact-free scaling up to 4K resolution. However, several drawbacks were noted during testing. The device lacks electronic lens controls, motorized zoom, or autofocus features, meaning image adjustments must be done entirely by hand. The initial setup guide contains a minor sequencing error where it attempts to pair a Google Account before establishing the network connection, forcing users to type passwords manually. Furthermore, it is available exclusively in a black finish, which may bother users looking for a discrete white model for living room ceiling installation. Lastly, while it includes a 120 Hz refresh rate option via HDMI-3, this is strictly limited to 1080p resolution due to downscaling limitations.

The BenQ W4100i is a 3,000-Euro smart 4K DLP projector that builds on its predecessor, the W4000i, by introducing dynamic tone-mapping for static HDR formats (HDR10 and HLG) and support for HDR10+. Utilizing a 0.65-inch Texas Instruments Full HD DLP chip with XPR-shifting technology, it generates a sharp 3,840 x 2.160 resolution. Its innovative four-LED light source optimizes brightness and eliminates the need for a color wheel, which practically eradicates the rainbow effect. Additional strong suits include an automatic color calibration sensor to counteract LED aging, comprehensive streaming app access via an included Android TV dongle, and outstanding out-of-the-box color accuracy with 99% Rec.709 coverage and an impressive 98% image illumination consistency. On the downside, achieving 100% of the wide DCI-P3 color gamut requires engaging an internal filter that triggers a massive 39% drop in brightness, leaving only 1,260 lumens—a level the reviewer found insufficient for impactful HDR highlights on screens wider than 2.5 meters. Disengaging the filter bumps brightness back up to a calibrated 2,080 lumens, but drops DCI-P3 coverage to 86%. Furthermore, black levels are inherently shallow at...

The BenQ W4100i is a black, 4K home cinema projector that successfully blends traditional dedicated theater performance with smart TV capability and high-end gaming features. Powered by a 4-LED light source, it delivers an impressive 2,000+ color-accurate lumens in its calibrated "Cinema" mode, utilizing a dynamic DCI filter to cover 84% of the BT.2100 HDR color space and dramatically improve black levels. Driven by Android TV 11 via an included Netflix-licensed QS02 media stick, the projector functions like a smart TV without needing external streaming boxes. Key installation and picture pros include a sharp variable zoom optic, generous manual horizontal (±15%) and vertical ( %) lens shift, native 24p/50Hz playback, and advanced ISF/Calman-ready calibration tools. Furthermore, it stands out as one of the first projectors to support full-bandwidth HDMI 2.1 (48 Gbit/s), enabling an ultra-low latency of 12–13 ms alongside astonishing gaming frame rates of 120 fps in Ultra-HD and 240 fps in Full-HD. Despite earning a "Very Good" overall score of 538 out of 650 points, the review highlights several distinct drawbacks. Its native contrast is limited by the...

The BenQ W4100i is a high-performance 4K HDR home cinema projector equipped with a modern 4LED light source that delivers a brilliant 3,200 ANSI lumens of brightness and 100% DCI-P3 wide color gamut coverage. Its core strengths include excellent image brightness, vibrant color accuracy, and advanced HDR-PRO™ technology utilizing global and local contrast enhancement to resolve fine details in challenging scenes. However, the primary drawback noted in the review is its native DLP contrast limitation in completely dark rooms, where deep black levels can appear slightly gray and washed out on traditional white screens. To maximize the projector's potential, the review highlights the necessity of pairing it with an Ambient Light Rejecting (ALR) contrast screen to artificially deepen black levels without discarding the unit's immense light output. It evaluates three ideal screen pairings depending on the user's viewing environment: the InVideo Obsidian Vision BrightTV (Gain 1.0) is recommended for daylight or ambient-lit living rooms because it boosts overall picture punch by 40%; the InVideo Obsidian Vision Cinema (Gain 0.6) serves as a contrast-focused solution for dim or dark evening settings...

The BenQ W4100i is a highly capable 4K HDR 4-LED home cinema projector that serves as a direct successor to the popular W4000i. It delivers exceptional out-of-the-box performance thanks to its factory-calibrated colors, which provide incredibly natural, authentic, and vibrant images. Boasting a high brightness of 3200 ANSI lumens, the projector maintains image visibility even in ambient daylight, though it achieves its peak dynamic depth and shadow detail in darkened rooms. It is highly versatile for complex living room setups, offering flexible installation via vertical and horizontal lens shift, a wide 1.15 to 1.5 throw ratio zoom range, and a digital corner correction feature. Furthermore, its modern interface is fast and highly responsive, integrating an AI-assisted HDR Cinema mode that enhances image sharpness while reducing visual noise in mid-lit scenes. On the positive side, the projector shines as a premium choice for both movie enthusiasts and gamers. Its single-chip DLP technology ensures pixel-perfect sharpness extending all the way to the edges of the frame. Gamers gain a massive advantage with its ultra-low input lag and true 4K resolution at 120Hz,...

BenQ W4100i Review Summary The BenQ W4100i is a robust, black home cinema projector that features significant internal upgrades over its predecessor, the W4000, despite retaining an identical physical design and lacking motorized zoom or focus control. Under the hood, it pairs a high-quality 0.65-inch DMD chip with the latest XPR3 pixel-shifting technology to effectively reduce motion artifacts and output a highly stable, razor-sharp 4K Ultra HD image. Its upgraded 4LED light source utilizes a unique RGBB system that achieves a powerful real-world calibrated brightness of 2,200 ANSI lumen (exceeding 3,400 lumen at peak maximum) without generating any annoying laser speckle. The projector excels as a versatile entertainment hub, offering extensive connectivity through three HDMI 2.1 ports with ALLM support, an integrated Google TV streaming stick, dynamic HDR-PRO™ tone mapping, and outstanding 3D capabilities. It also shines as an excellent gaming companion, boasting a remarkably low input lag of 17.9 ms at 4K/60Hz, which drops even further to just 6.5 ms at 1080p/240Hz.
