The evolution of home cinema projection has reached a new milestone — and it’s called the BenQ W4100i. Combining true 4K HDR resolution, 100% DCI-P3 cinematic color accuracy, and a long-lasting 4-LED light engine, this projector stands as one of BenQ’s most complete offerings to date.
It’s built for serious enthusiasts — those who crave the visual fidelity of a premium cinema setup but want the convenience of Android TV with built-in Netflix, effortless installation, and a lifespan that outlasts traditional lamp projectors. The W4100i doesn’t just promise lifelike visuals — it delivers a cinematic experience that feels handcrafted for movie lovers, gamers, and home theater perfectionists alike.
- PROJECTOR-OPTIMIZED TRUE 4K UHD and HDR: HDR-PRO technology exclusive Local Contrast Enhancer and Tone Mapping for perfect details in dark and bright scenes. 8.3 Million Pixels give awe-inspiring 3840 x 2160 image quality and deliver incredible clarity and crisp defined cinematic details.
Design & Build – Modern, Functional, and Cinematic
The BenQ W4100i has a sleek, understated elegance — a clean matte-gray finish and symmetrical body that communicates refinement and purpose. Everything feels solid, from the lens housing to the adjustment dials. Despite its performance-oriented internals, it’s compact enough to fit on a coffee table or mount easily to a ceiling without dominating the room.
BenQ’s design philosophy shines through in small details — the dedicated slot for the included Android TV (QS02) dongle, tidy cable management, and accessible lens shift dials make installation stress-free. The cooling vents are intelligently placed to minimize fan noise while maintaining airflow, keeping the projector whisper-quiet even during extended movie sessions.
It’s a projector that looks professional yet homely — blending beautifully into both minimalist setups and dedicated theater rooms.
Image Quality – 4K Precision Meets LED Longevity
At the heart of the W4100i lies BenQ’s 4-LED light engine, an upgraded architecture that produces more brightness, richer color, and superior light stability than conventional LED systems. Rated at 3,200 ANSI lumens, it’s bright enough for semi-lit rooms while still achieving cinematic depth in darker environments.
The 4K UHD resolution (3840×2160) — generated via advanced XPR pixel-shifting — delivers crystal clarity across every frame. Fine details like skin pores, fabric textures, and shadow gradients are rendered with remarkable precision. Even large 120–150″ screens remain tack-sharp with no visible pixelation.
With factory calibration targeting both 100% DCI-P3 and 100% Rec.709 color space coverage, you’re seeing what the director intended. The factory-calibrated color accuracy (Delta E < 3) means you can plug it in and enjoy cinematic color right away — no professional calibration required, though it’s available for perfectionists.
HDR Performance – Dynamic, Lifelike, and Truly Cinematic
HDR is where the W4100i really flexes its muscle. Supporting HDR10, HDR10+, and HLG, it dynamically adjusts tone mapping on a frame-by-frame basis using BenQ’s proprietary HDR-PRO™ engine. The result is stunning contrast and highlight control — bright scenes retain brilliance without overexposure, while dark sequences preserve every subtle texture and shadow.
Movies mastered in HDR10+ truly come alive — from the blazing sunlight of desert scenes to the nuanced glow of candlelight in period dramas. The difference isn’t just visual; it’s emotional — every tone and highlight feels true-to-life.
With 3,000,000:1 dynamic contrast and accurate brightness balance, the W4100i brings a tangible sense of depth that rivals far more expensive laser projectors.
Motion & Gaming – Fluid, Responsive, and Versatile
BenQ designed the W4100i not just for film lovers, but for gamers and sports fans too. It supports 4K 60 Hz playback with a low 17.9 ms input lag, ensuring smooth performance for casual and cinematic gameplay. Drop the resolution to 1080p at 240 Hz, and latency shrinks to an incredible 6.5 ms, perfect for competitive players who demand precision timing.
Fast action scenes — whether it’s a racing sim or an action blockbuster — appear crisp, with no noticeable blur or ghosting. Combined with BenQ’s motion enhancement technology, movement feels fluid yet natural, without the over-processed “soap opera” effect that plagues lesser HDR projectors.
Smart Features – True Android TV Built-In
Forget external streaming sticks and extra cables. The W4100i comes with BenQ’s QS02 Android TV dongle, neatly tucked into a hidden HDMI slot. It gives you direct access to Netflix, Prime Video, Disney+, YouTube, and thousands of other apps — all certified and fully supported.
Voice control through Google Assistant adds convenience, and Chromecast Built-in allows seamless casting from your phone or laptop. You can start a movie, stream music, or mirror your screen in seconds.
This makes the W4100i a genuine standalone entertainment system — ready to stream out of the box, with no additional devices required.
Audio & Connectivity – Flexible, Future-Proof, and Immersive
While built-in projector speakers are rarely impressive, BenQ includes a 5W chamber-tuned speaker that’s clear enough for casual viewing. For a true cinematic soundstage, the HDMI 2.1 port with eARC support lets you connect directly to soundbars or AV receivers for full Dolby Atmos and DTS:X audio output.
Connectivity options include:
- 3 × HDMI 2.1 (HDCP 2.3) for next-gen devices
- USB-A & USB-C ports for storage and power
- Optical audio out & RS232 control for advanced setups
- LAN port and Wi-Fi for network flexibility
This combination ensures future compatibility with modern consoles, 4K Blu-ray players, and streaming gear — keeping your setup ready for years to come.
Installation & Adjustability – Effortless Placement Freedom
The W4100i is one of the easiest high-end projectors to install, thanks to its 4-way lens shift system — offering up to 60% vertical and 15% horizontal adjustment — and 1.3× optical zoom.
Whether you’re ceiling-mounting or placing it on a shelf, these adjustments let you perfectly align the image without losing resolution or introducing digital distortion. Combined with 2D keystone correction, setup becomes intuitive even in tight or asymmetrical rooms.
This flexibility is what separates the W4100i from most competing projectors in its price range — it adapts to your space, not the other way around.
Performance Summary – Real-World Experience
Fire up a 4K Blu-ray or HDR stream, and the difference is immediately clear. Colors are lush but accurate, brightness is balanced across the frame, and fine textures hold steady even in motion. Animated films explode with vibrancy, while live-action dramas benefit from nuanced tonality and shadow depth.
Unlike lamp-based projectors, brightness and color remain consistent over time — no dimming or color shift even after hundreds of hours. And with a rated LED lifespan of up to 30,000 hours, you can watch a movie every night for more than a decade before worrying about replacements.
Simply put, the BenQ W4100i delivers that rare mix of technical precision and emotional impact — a projector that disappears and lets the content shine.
