The BenQ W4100i is a 4K LED home cinema projector built for serious movie and streaming quality, with 100% DCI-P3 and 100% Rec. 709 colour coverage and a 3,000,000:1 contrast ratio. Every unit ships with an individual factory calibration report, giving out-of-box colour accuracy that BenQ describes as true Hollywood colour rather than something that needs to be set up after purchase.
AI Cinema Mode analyses each frame in real time and automatically optimises HDR, colour saturation, and sharpness, which is particularly useful for compressed streaming content from Netflix, Disney+, and Prime Video where source quality varies. HDR-PRO technology uses multi-stage light control with a Global Contrast Enhancer, a Local Contrast Enhancer working across more than 1,000 independent regions per frame, and Dynamic Black tone mapping, working together to preserve detail in both bright and dark scenes. HDR10, HDR10+, and HLG are all supported, and Filmmaker Mode preserves the director's intended motion cadence, colour, and brightness, including judder-free 24P playback. ProHiFi is an authorised BenQ dealer in India.
Installation flexibility is considerably more advanced than BenQ's entry-level models. A 1.3x zoom is paired with 4-way lens shift, vertical from 0% to 60% and horizontal up to plus or minus 15%, giving a perfectly straight-edged image with no loss of resolution even when the projector cannot be placed dead-centre to the screen. The W4100i includes a Google-licensed Android TV dongle (QS02) as standard, providing Netflix, Prime Video, Disney+, YouTube, and over 700,000 titles via Google Play, alongside 11-level colour temperature tuning for advanced calibration.
Connectivity is built for both cinema and gaming. Three HDMI 2.1 inputs (HDCP 2.3) include one supporting 4K/120Hz and eARC with Dolby Atmos pass-through. Input lag reaches 17.9ms at 4K/60Hz and drops to 6.5ms at 1080p/240Hz, with automatic ALLM detection from connected consoles. RS232 and a 12V trigger support custom installation and control system integration.

Why Consider the BenQ W4100i
The W4100i is the right choice for film and streaming enthusiasts who want colour accuracy and installation flexibility well beyond BenQ's entry-level projectors. The combination of factory calibration, 100% DCI-P3 coverage, and 11-level colour temperature tuning matters most to viewers who are particular about how a film actually looks rather than simply how bright it is. The 4-way lens shift is a genuine practical advantage in Indian homes where the projector often cannot be mounted in the theoretically ideal position relative to the screen, removing the need for digital keystone correction and its associated loss of sharpness. With three HDMI 2.1 ports, sub-7ms input lag at high refresh rates, and the same AI Cinema Mode that elevates lower-quality streaming sources, the W4100i is equally credible for a dedicated home cinema room and a serious gaming setup.
Ideal for
- Film enthusiasts wanting factory-calibrated, wide-gamut colour accuracy out of the box
- Installations where the projector cannot be centred on the screen, using 4-way lens shift
- Streaming-heavy households wanting AI Cinema Mode to improve compressed content
- Gamers needing 6.5ms input lag at 1080p/240Hz alongside genuine 4K cinema quality
- Custom installations requiring RS232 and 12V trigger control
- Those who want Netflix, Disney+, and Prime Video built in without a separate streaming box
