BenQ has delivered another standout product with the BenQ X3100i, a True 4K Gaming Projector that promises unmatched performance for gamers and movie fans alike. With its 4LED light source, ultra-low latency, and a vibrant DCI-P3 100% color gamut, this projector is aimed at those who want big-screen gaming alongside cinematic experiences. Priced at $2,399, it sits at the premium end of the gaming projector market and promises to raise the bar with future-proof tech. But does it fulfill its lofty ambitions? Let’s take a deep dive.

Design and Build Quality
The BenQ X3100i features a modern, cubic design that immediately stands out. Its white sides, black front panel, and contrasting orange trim provide a sleek, premium look fitting for any entertainment or gaming setup. At 10.7 x 8.4 x 10.2 inches and weighing 15 pounds, it’s compact yet robust, suitable for both permanent installations and portable setups.
Setup Flexibility: A Gamer’s Dream
Setting up the X3100i is easy, thanks to its manual lens controls, including 1.3x optical zoom and 10% vertical lens shift. Unlike many competitors at this price point, it boasts flexibility for diverse room layouts, whether mounted on a ceiling or placed on a table. However, the lack of motorized focus and zoom is a missed opportunity that could have enhanced the user experience further.
What Stands Out:
The vertical lens shift is particularly handy for adjusting image placement without having to tilt the projector, avoiding the distortions that can result from keystone correction. This gives users greater control over setup precision—a feature often lacking in similarly priced rivals.
Visual Performance: Serious Punch for Gaming and Movies
4LED Light Engine: Bright and Reliable
One of the BenQ X3100i’s most notable advancements is its 4LED light source, which ensures vibrant and enduring brightness rated at 3300 ANSI lumens. This makes it suitable for both darkened home theaters and rooms with moderate ambient light. The LED light source also promises 30,000 hours of use, translating to years of bright imagery without replacements—a stark advantage over lamp-based projectors.
DCI-P3 Color Coverage: Vivid and Accurate
Color accuracy is another area where the X3100i excels. With 100% DCI-P3 coverage, it delivers sharp, vivid, and true-to-life colors that enhance modern content. Movies like Dune look spectacular, with well-saturated hues and a cinematic vibrancy you’d expect from high-end TVs. Compare this to competitors like the Optoma UHZ50, which caps out at ~80% of the DCI-P3 gamut, and the BenQ clearly takes the lead here.
HDR Performance: The Good and the Middling
The BenQ X3100i supports HDR10+ and HLG, with Dynamic Black Technology enhancing highlight and shadow details. Bright scenes, such as fireworks displays or dynamic outdoor vistas, shine with depth and clarity.
However, while HDR content looks great overall, the X3100i’s black levels can fall short in fully dark environments. Unlike projectors with laser or triple-laser technologies (for example, the Epson LS500), dark scenes can appear slightly muted—a tradeoff that might disappoint those looking for a cinema-quality experience in pitch-black rooms.

Gaming Performance: Instantaneous and Immersive
The X3100i is built for serious gamers, with low latency as its centerpiece. Whether playing 162fps shooters or RPGs like Elden Ring, this projector ensures seamless on-screen responsiveness. Testing confirmed its ultra-low input lag at:
- 4.2ms at 1080p/240Hz
- 8ms at 1440p/120Hz
- 16ms at 4K/60Hz
For competitive gaming, the X3100i’s suite of tailored presets (FPS, RPG, SPG, and RCG modes) optimizes image and sound based on genre, enhancing vibrancy, motion clarity, and dark detail visibility. While it lacks native 4K/120Hz support, a feature growing increasingly popular with next-gen consoles like PS5, its ultra-low latency remains one of the best in the market.
What’s Missing for Gamers: Gamers with high refresh rate ambitions may also notice the lack of Variable Refresh Rate (VRR) support, which is becoming a standard feature on higher-end gaming projectors.
Smart Features: Functional but Not Flawless
Android TV 11 and the QS02 Dongle
The X3100i ships with BenQ’s QS02 streaming dongle, upgrading performance over the previous-gen QS01. With support for Netflix, Disney+, and other major platforms, Android TV makes this projector function as a convenient one-stop entertainment hub. The inclusion of Google Chromecast and AirPlay enhances its connectivity options, making it easy to cast content from multiple devices.
However, Android TV on the X3100i suffers from occasional delays and crashes, particularly when switching between apps. Additionally, since the QS02 dongle takes up one of the HDMI ports, users needing multiple inputs might find themselves juggling between devices if they hook up consoles or Blu-ray players.
Verdict on Streaming:
Competent but not exceptional. Power users or frequent streamers might want to rely on an external media player like a Fire TV Stick or Apple TV for a smoother interface.
Built-In Speakers: Small but Mighty
BenQ integrates TreVolo-tuned stereo speakers (10W total) for onboard sound. While not comparable to standalone soundbars or audiophile-grade systems, these speakers deliver respectable clarity and volume, making them suitable for casual movie nights or light gaming sessions.
For immersive setups, the eARC compatibility allows seamless Dolby Atmos audio transmission to external sound systems, elevating the X3100i to home theater-grade audio without limitations.
