The BenQ X3100i is BenQ's flagship 4K console gaming projector, built specifically around the needs of serious console and PC gamers rather than adapted from a cinema design. It combines 100% DCI-P3 colour coverage and 4LED brightness with input lag as low as 4.2ms, putting it among the fastest-responding 4K-capable projectors available for competitive and immersive gaming alike.
Four dedicated game genre modes tune both picture and sound for the content being played: RPG Mode deepens bass and cinematic realism, SPG Mode sharpens colour and vocal clarity for sports, FPS Mode enhances dark detail and audio clarity to spot threats faster, and RCG Mode highlights engine and road sound for racing titles. Auto Game Mode automatically detects whether a PlayStation, Xbox, or Switch is connected and recalls the previously used settings for that console, and an FPS Crosshair overlay projects a targeting reticle onto the screen for competitive shooters. ProHiFi is an authorised BenQ dealer in India.
Audio is handled by BenQ's CinematicSound technology with a dedicated Bongiovi DPS processor, creating a 3D spatial audio field through the built-in 5W chamber speakers so in-game sound effects carry genuine sense of depth and direction, a meaningful step up from typical built-in projector speakers. HDR-PRO technology combines tone mapping with SSI Dynamic Black to reveal shadow detail without washing out bright scenes, and the 4LED light source delivers a 12% brightness boost over 3LED designs and 25% bolder colour than lamp-based projectors, with up to 30,000 hours of light source life and zero lamp replacement.
A Google-licensed Android TV dongle is included as standard, giving direct access to Netflix in true 4K alongside more than 5,000 apps via Google Play, voice search, and Google Assistant. Vertical lens shift between 40% and 60% provides ceiling or tabletop installation flexibility, a 1.3x zoom with a 1.15 to 1.5 throw ratio projects a 100-inch screen from just 2.5 metres, and digital zoom extends framing options further. Dual HDMI 2.0b inputs cover 4K/60Hz and 1080p/120Hz console connections, with HDMI eARC carrying Dolby Atmos and 7.1 channel audio to a connected soundbar or AV receiver over a single cable.

Why Consider the BenQ X3100i
The X3100i is the right choice for serious console and PC gamers who want a true 4K projector built around gaming first, not a cinema projector with gaming features bolted on. Sub-5ms input lag at high refresh rates is genuinely competitive territory, and the four dedicated genre modes mean an open-world RPG, a competitive shooter, a sports title, and a racing game are each tuned with appropriate picture and audio characteristics rather than one generic gaming preset trying to cover everything. The Bongiovi DPS-powered spatial audio is a real differentiator against projectors that simply include louder built-in speakers without any spatial processing, giving genuine directional cues that matter in fast-paced gameplay. Auto Game Mode and the included Android TV dongle round it out as a single device that handles console gaming, PC gaming, and streaming without compromise on any of them.
Ideal for
- Serious console and PC gamers wanting sub-5ms input lag at high refresh rates
- Multi-genre gamers who want dedicated FPS, RPG, SPG, and RCG picture and audio tuning
- Competitive shooter players using the FPS Crosshair overlay feature
- Households switching between PS5, Xbox, and Switch using Auto Game Mode detection
- Gaming setups wanting genuine spatial audio from built-in speakers via Bongiovi DPS
- Those wanting 4K Netflix and streaming built in without a separate device
