Overview
The BenQ W4100i is aimed at home cinema enthusiasts who want to combine uncompromising colour accuracy with 100 % DCI-P3 and true 4K UHD sharpness in a flexibly positionable projector. The 4LED light source delivers 3,200 ANSI lumens and does away with lamp changes for good. With Filmmaker Mode, HDR10+ and a factory calibration report included, every film looks exactly as the director intended. The included Netflix-certified QS02 Android TV dongle turns the W4100i into a fully fledged streaming centre.

Picture quality
The W4100i uses DLP technology with a 0.65" DMD chip and outputs 4K UHD resolution (3,840 × 2,160 pixels) – 8.3 million pixels for razor-sharp detail. The 4LED light source produces 3,200 ANSI lumens, delivering a convincing image even in rooms that are not fully darkened. Dynamic contrast reaches 3 million:1 thanks to the Dynamic Black function, which dims the light source depending on the scene, enabling deep blacks in dark film passages.
CinematicColor™ technology covers 100 % of the DCI-P3 colour space – meaning colours just as the director saw them in colour grading, without compromise. The projector supports HDR10+, HDR10 and HLG. HDR10+ provides dynamic metadata (used by Amazon and Samsung) that optimises each scene individually. HLG is designed for TV broadcasts and streaming services with live content. BenQ's proprietary HDR Pro™ and dynamic tone mapping additionally adapt the dynamic range to the projector's actual capabilities.
Filmmaker Mode plays films with motion smoothing switched off and faithful colour tuning. Films are played at their original 24 frames per second – without distracting judder from 3:2 pulldown. AI Cinema mode analyses image content and automatically optimises brightness and contrast scene by scene.
Sound
The W4100i has a built-in 5-watt mono speaker with BenQ's treVolo chamber technology. The speaker is adequate for occasional film nights without an external system – for a full home cinema experience, we recommend an external soundbar or AV receiver.
Audio outputs include a 3.5 mm jack and an SPDIF output (optical/coaxial) with 5.1-channel audio pass-through. HDMI 2 supports Audio Return Channel (ARC) with 5.1, 7.1 and Dolby Atmos pass-through – so lossless audio formats are also passed on to the AV receiver. The 12V trigger output enables automatic control of motorised screens or masking systems.
Smart features & streaming
The QS02 Android TV dongle is included; it plugs directly into the projector and brings Google-certified Android TV. Netflix, the Google Play Store and all popular streaming services are accessible through it – no additional streaming stick needed. It is operated via the supplied QS02 remote control with microphone for Google voice search.
Installation & projection
Note on room planning: add 32 cm housing depth plus approx. 10–15 cm for cable connections to the calculated throw distance.
| Image size (diagonal) | Image width (approx.) | Throw distance |
|---|---|---|
| 80 inches (203 cm) | 177 cm | min. 1.77 m – max. 2.64 m |
| 90 inches (229 cm) | 199 cm | min. 1.99 m – max. 2.97 m |
| 100 inches (254 cm) | 221 cm | min. 2.21 m – max. 3.30 m |
| 120 inches (305 cm) | 266 cm | min. 2.66 m – max. 3.97 m |
The W4100i offers 1.3x optical zoom, vertical lens shift of 0–60 % and horizontal lens shift of up to ±15 %. This allows considerable flexibility in placement – the projector does not have to be positioned exactly centred in front of the screen. Automatic vertical and horizontal keystone correction (±30° each) and Corner Fit electronically compensate for any remaining distortion.
For rooms with ambient light, we recommend an ALR screen (ambient light rejecting), which absorbs ambient light and improves contrast.
Light source & operation
The W4100i uses a 4LED light source that lasts up to 20,000 hours in normal mode and up to 30,000 hours in Eco mode. No lamp changes needed – the light source lasts the entire life of the projector.
| Operating mode | Lifetime | 3 hrs/day | 6 hrs/day |
|---|---|---|---|
| Normal | 20,000 hours | approx. 18.5 years | approx. 9.0 years |
| Eco | 30,000 hours | approx. 27.5 years | approx. 13.5 years |
In normal mode, the W4100i runs at 30 dB(A), and at 29 dB(A) in Eco mode. Both values are audible but not distracting – no problem with action films. For quiet dramas or arthouse cinema, Eco mode is recommended as it reduces the noise level slightly. The 12V trigger output enables automatic control of motorised screens or masking systems.
Conclusion
The BenQ W4100i is the right choice for film fans who refuse to compromise on colour accuracy: 100 % DCI-P3, Filmmaker Mode and an included factory calibration report guarantee cinema-accurate images from the moment you switch it on. The 4LED light source with up to 30,000 hours of life and the supplied QS02 Android TV dongle make it a low-maintenance, fully connected home cinema hub for the long term. If you want flexible placement via lens shift, true 4K UHD sharpness and HDR10+ in one unit, the W4100i is a convincing all-rounder for demanding everyday home cinema use.
