Design and Build
The BenQ X500i features a compact, portable form factor designed for tabletop mounting, with dimensions of 14.1″L x 9.6″W x 4.6″H and a weight of 11 pounds. Its white chassis is utilitarian, focusing on function over flashy gamer aesthetics, which allows it to blend into various room decors. The design incorporates a short-throw lens positioned off-center, a necessity for its projection characteristics. Build quality, inferred from manufacturer details, appears geared towards home use, with a focus on the internal 4LED light engine that is noted for being brighter and longer-lasting than traditional lamp-based systems.
The unit’s form factor supports its role as a space-saving solution. Its short-throw capability is the defining physical trait, enabling large images from very short distances. This design directly caters to the product’s core use case: delivering a cinematic or gaming experience in rooms where placing a projector far from the wall or screen is not feasible. The inclusion of symmetrical speakers on the front also influences the design, aiming to provide balanced audio output directly from the unit.
Performance and Features
Visual Performance and Gaming
The visual performance of the X500i is anchored by its 4K UHD resolution and BenQ’s HDR-PRO technology, which is designed to enhance clarity and detail. The 4LED light source delivers the stated 2200 ANSI lumens of brightness, which is crucial for maintaining image vibrancy. For gaming, the headline feature is the exceptionally low input lag of 4.2 milliseconds when operating at 1080p resolution with a 240Hz refresh rate. This is targeted squarely at competitive fast-paced gaming. It is important to note that input lag increases to 16 milliseconds when displaying native 4K content at 60Hz, which is still respectable for console gaming and single-player experiences but not in the same ultra-responsive tier as the 1080p mode.
Additional gaming-oriented features include auto game modes, where the projector can recognize connected consoles like a PS5 or Nintendo Switch and adjust settings automatically. A dedicated FPS crosshair tool is also included for certain titles. The projector supports a dynamic contrast ratio of 600,000:1, aiming to produce deep blacks alongside bright highlights, a key factor for HDR content. The 1.2x optical zoom and digital zoom offer some flexibility in image sizing without moving the projector, though the zoom range is noted as a potential limitation for placement flexibility.
Connectivity and Smart Features
Connectivity is centered on HDMI, with the specifications listing HDMI as the primary hardware connectivity technology. The manufacturer’s description confirms support for eARC and S/PDIF connectivity for advanced audio pass-through. A notable point from user feedback is the lack of an Ethernet port, making a stable Wi-Fi connection important for its smart features. The built-in Google-Certified Android TV is a major convenience feature, providing access to streaming apps like Netflix, Prime Video, and YouTube directly without an external stick. It also supports casting via AirPlay and Chromecast from Apple and Android/PC devices.
The smart platform enables the projector to function as a standalone entertainment hub. However, user reviews mention that the proprietary SettingsXchange feature, which allows users to share optimized display settings for specific games, has a limited library of supported titles at launch. This highlights a potential area where the ecosystem is still developing compared to the core hardware performance.
Audio Performance
The BenQ X500i incorporates a TreVolo audio system with symmetrically placed speakers. Beyond general playback, it includes specialized Game Sound Modes tuned for different content types like FPS and RPG games, as well as cinematic viewing. The system supports immersive audio formats, including 7.1-channel virtual surround and Dolby Atmos, via its eARC and S/PDIF connections. This allows users to connect a higher-end sound system for a more enveloping experience. Owner feedback on the built-in sound describes it as good, with some noting it could be more powerful, but the inclusion of dedicated tuning modes and high-quality audio pass-through options adds significant value for an all-in-one solution.
Setup, Support and Ownership
Setup is reported by owners to be straightforward, with features like auto focus and digital keystone correction aiding in achieving a proper image alignment quickly. The short-throw design simplifies placement in tight spaces, though the limited 1.2x zoom means the projector’s position needs to be fairly precise to achieve the desired screen size. The product is listed as 3D-ready and includes a remote control and user manual. BenQ provides a two-year manufacturer’s warranty, offering a standard level of support for a projector in this class.
Long-term ownership is influenced by the durable 4LED light source, which has an operating life of up to 20,000 hours, reducing maintenance concerns compared to traditional lamps. As a device with built-in Android TV, receiving regular software and security updates for the smart platform would be an important aspect of its ongoing performance and feature set, though a specific update policy is not detailed in the provided data. For those looking to expand their setup, the projector’s compatibility with gaming consoles and support for external audio systems are key upgrade paths.
What Owners Say
Overall owner sentiment is positive, reflected in the 4.2 out of 5-star rating. The majority of reviews are 5-star, with praise frequently focused on the impressive picture quality, bright and vibrant colors, and the buttery-smooth gaming performance enabled by the low input lag. Many users are delighted with the short-throw capability, allowing them to install large screens in garages, bedrooms, or other confined spaces. The built-in Android TV and easy setup process are also commonly highlighted as major benefits.
Critical feedback from owners tends to focus on specific limitations rather than core failures. Some note that the built-in audio, while good, may not satisfy audiophiles. The lack of an HDMI 2.1 port is mentioned as a drawback for users with very high-end PCs seeking to leverage the latest features. Several reviews point out that the best image quality is achieved in a darkened or semi-dark room, which is typical for projectors but worth considering for intended use environments. The absence of an Ethernet port is also noted as a consideration for ensuring stable streaming.

Who Should Buy It (and Who Should Skip It)
The BenQ X500i is an ideal choice for gamers with limited space who prioritize fast-paced, responsive gameplay on a big screen. It’s perfectly suited for a bedroom, apartment, or dedicated mancave where a traditional long-throw projector isn’t feasible. Home theater enthusiasts looking for an all-in-one 4K streaming solution with good picture quality will also find it compelling. If your primary use case involves competitive multiplayer titles at 1080p and you value the convenience of built-in apps, this projector is a strong candidate.
Conversely, users who primarily game at native 4K resolution on next-gen consoles or high-end PCs and demand the absolute lowest possible latency might find the 16ms lag a compromise. Those with very bright, uncontrolled living rooms may not achieve the best results. If you require extensive placement flexibility with a large zoom range or must have wired Ethernet and HDMI 2.1 connectivity, you may want to explore other models. For more general display options, our guides on the best monitors or specific gaming setup gear offer alternative approaches to enhancing your space.
Final Verdict
The BenQ X500i successfully carves out a niche as a high-performance short-throw projector with a sharp focus on gaming. Its standout 4.2ms input lag in 1080p mode is a legitimate asset for competitive players, while the 4K HDR-PRO image quality and bright 4LED engine deliver a compelling cinematic experience. The integration of Android TV and capable audio systems eliminates the need for multiple external devices, creating a clean and user-friendly setup. For its target audience of space-constrained gamers and entertainers, it delivers on its core promises effectively.
