BenQ W4000i Review | 84 Data compared

The BenQ W4000i is a 4K home cinema projector equipped with a 4LED light source that utilizes an extra blue diode filtered into green to significantly boost brightness output. In terms of performance pros, the projector slightly exceeds its marketed specifications in "Bright" mode by hitting 3,260 lumens. However, for optimal viewing, the calibrated "Cinema" mode delivers a highly color-accurate 1,770 lumens that can cleanly illuminate screens up to 4.30 meters wide in SDR. Furthermore, it boasts exceptional brightness uniformity and color homogeneity across the screen at an unweighted average of 96%, ensuring that no visible deviations or color temperature fluctuations disrupt the image. Its "Motion Enhancer 4K" frame interpolation on the "Low" setting effectively counters XPR-shift judder to maintain a sharp, artifact-free film look. On the downside, the projector falls massively short of the manufacturer's bold 2,000,000:1 dynamic contrast claim, as the LEDs do not completely shut off during all-black scenes. It registers a standard native static contrast of 1,030:1 for SDR and 1,045:1 for UHD, which is typical for DLP technology but leaves the black level looking more...

The BenQ W4000i is an innovative 4LED home cinema projector that addresses traditional lamp and laser limitations by delivering an impressive brightness of up to 3,200 lumens. Utilizing a unique fourth blue LED alongside a larger 0.65-inch DLP chip, it yields exceptional sharpness, an increased in-image contrast, and highly natural color accuracy for both SDR and HDR content. Key strengths include a long lifespan of 30,000 hours, an integrated Android TV system with native Netflix support, a gaming-friendly low input lag of 17.8ms at 4K/60Hz, and a smooth 120Hz frame interpolation system. Additionally, its double factory-calibrated color profiles ensure reference-level performance right out of the box. Despite these advanced technical capabilities, the projector exhibits a few notable drawbacks. Its primary weakness is a limited native contrast ratio, resulting in a slight gray haze over deep black levels during dark cinematic scenes—a vulnerability that cannot be completely bypassed because dynamic LED dimming is disabled during high-end HDR playback. Furthermore, maximizing color accuracy with the "Wide Color Gamut" filter causes a noticeable light loss of roughly 40%, dropping the brightness down to...

The AV-Magazin review gives the BenQ W4000i a score of "very good to outstanding" and highly praises its features. A big pro is the 4LED light source that lasts up to 30,000 hours, ensuring long-term movie fun. The review also cheers the factory color calibration for Rec.709 and DCI-P3 standards, which gives you perfect colors right out of the box. Setting it up is very easy thanks to the generous lens shift tool. Plus, it has built-in Android TV for quick streaming. However, the review does point out a couple of downsides. At a retail price of 2,999 Euros, this projector is a major investment. While it lists features like an external USB media interface, it relies on an added internal dongle area for its smart system. Overall, AV-Magazin says it sets a very high bar for rival brands.
