True 4K UHD projection with HDR-PRO

The BenQ W4100i is a DLP home-theater projector that delivers native 3840×2160 resolution using 8.3 million pixels. A 4LED light source rated at 3200 lumens provides up to 10+ years of operation. Factory calibration covers 100% of the DCI-P3 colour space and 709 for accurate cinematic reproduction. HDR-PRO technology with local contrast enhancement and dynamic tone mapping optimises bright and dark detail in real time.

Flexible installation and smart streaming

Buyers who need versatile placement will benefit from 1.3x zoom, 2D lens shift with ±30° vertical and horizontal correction, and a throw ratio of 1.15~1.50. Certified Android TV with Netflix pre-loaded, AirPlay, Google Cast, Bluetooth 5.0 and dual-band Wi-Fi handle streaming directly. Two HDMI 2.1 ports support 4K 60 Hz with ALLM; a third HDMI 2.1 input accepts 4K 120 Hz signals downscaled to 1080p 120 Hz. This unit is not for buyers who require native 4K 120 Hz display or HDMI 2.1 VRR gaming features.

3,000,000:1 dynamic contrast ratio

The projector achieves a 3,000,000:1 contrast ratio through multi-stage light control and global and local contrast enhancers that adjust over 1000 regions per frame. This specification determines how well the image separates shadow detail from highlight retention in dark-room viewing.

Questions about this item

Does the BenQ W4100i come with everything needed to start watching, or do I need to buy extra cables or a streaming stick?

The projector ships with Android TV and Netflix pre-loaded, plus built-in Wi-Fi 802.11 a/b/g/n/ac and Bluetooth 5.0 for wireless casting via AirPlay or Google Cast. Two HDMI 2.1 ports and one HDMI 2.1 port supporting 4K 120 Hz downscaling to 1080p 120 Hz are provided, so only source cables are required.

The spec sheet lists 3200 lumens and 100 % DCI-P3 — which version or mode should I choose for the best colour accuracy?

The W4100i is a single SKU with factory-calibrated CinematicColor covering 100 % DCI-P3 and Rec.709 out of the box. No alternate colour-capacity versions exist; select the appropriate HDR-PRO picture mode (HDR10, HDR10+ or HLG) for the content you are playing.

What does the 3,000,000:1 contrast ratio actually look like in a darkened living room with the 4LED light source?

The 4LED engine delivers a dynamic contrast ratio of 3,000,000:1 combined with HDR-PRO Global and Local Contrast Enhancers that adjust over 1,000 zones per frame, producing deep blacks and bright highlights simultaneously on the 8.3 million-pixel 4K UHD image.
