BenQ GP520 4K Projector Review: Premium Home Theater Performance

Introduction

The BenQ GP520 is a premium 4K projector that delivers theater-level image quality for home entertainment. With native 4K resolution, HDR support, built-in Android TV, and distinctive features like 3D projection capability, it targets viewers who want a cinematic experience without leaving home. This review covers its performance across movies, gaming, and multimedia, along with the practical considerations that come with its premium positioning.

Design and Build

The GP520 weighs 3.7 kilograms, or approximately 5 kilograms with the power adapter, making it portable enough for travel or repositioning within a home. The projector includes a 1.4-inch tripod mount on top and additional mounting points on all three sides, allowing flexible installation on ceilings, shelves, or stands in various orientations.

The physical design incorporates practical features for a projector of this class. The lens sits recessed, eliminating the need for a lens cap and reducing scratch risk. Dual 12-watt speakers are built into the left and right sides, with air intake vents that support the internal cooling system necessary for the lamp operation.

Connectivity is comprehensive. The projector includes two USB 2.0 ports (one for service and firmware updates, one for external storage up to 32GB), a USB Type-C port with 18-watt power delivery and 4K 60FPS display output support, two HDMI 2.1 ports (one with eARC support for soundbar integration), and a 3.5-millimeter auxiliary port. Wi-Fi 6 and Bluetooth 5.2 enable wireless casting and speaker connectivity.

The remote supports both infrared and Bluetooth connectivity, offering flexibility in how you control the projector. A smartphone app called Smart Remote provides an alternative control method for both Android and iOS devices, though iOS casting has limitations due to HDCP restrictions.

Display Quality and Resolution

The GP520 projects native 4K Ultra HD at 3840x2160 resolution in a 16:9 aspect ratio. Projection size ranges from a minimum of 50 inches to a maximum of 180 inches. In testing at approximately 100 to 110 inches, the image clarity remained excellent, with consistent color and sharpness across the entire projection area, including the corners where many projectors show degradation.

Brightness is rated at 2600 ANSI Lumens, a specification that uses the American National Standards Institute standard rather than manufacturer-inflated lumen claims. The contrast ratio of 531:1 ensures that blacks remain visible and distinct even with the lamp active, a notable achievement for a projector.

HDR performance is a standout feature. When watching HDR content, the projector handles both the brightest and darkest areas of the image with visible detail and dynamic range. The auto cinema picture mode optimizes the image based on content type, and motion smoothing (MEMC) can convert 30FPS content to 60FPS for smoother playback.

The lamp offers exceptional longevity: 30,000 hours in eco mode or 20,000 hours in normal mode. At approximately 2 to 2.5 hours per movie, this translates to thousands of hours of viewing before lamp replacement becomes necessary.

Autofocus and Keystone Correction

The autofocus system responds automatically when the projector is moved forward or backward, refocusing within 3 to 4 seconds. A dedicated button on the remote triggers automatic keystone correction, which straightens the projected image if the projector is tilted or positioned at an angle. This eliminates the need for manual adjustment in most scenarios.

Additional image adjustment options include digital zoom and repositioning controls for fine-tuning the projection placement. The projector includes an avoid obstacle feature that automatically shifts and reduces the projection size if an obstruction like a table or chair blocks part of the beam.

Smart eye protection automatically reduces brightness if someone approaches within 1 to 2 meters of the projector, a safety feature particularly useful in households with children.

Operating System and Smart Features

The GP520 runs Android 11 with a customized Google TV interface. Unlike some projectors that require switching inputs to access streaming apps, all settings and applications are integrated into the Google TV environment. Netflix is available directly, a feature not always present in Google TV implementations.

The interface supports Google Assistant voice control and allows installation of additional applications from the Google Play Store. Performance is generally smooth, though occasional lag or stuttering can occur when navigating settings or opening certain applications, consistent with typical Google TV behavior.

Casting works reliably on Android devices. iOS casting is supported but limited by HDCP restrictions on certain content.

Audio Performance

The dual 12-watt speakers deliver surprisingly capable sound for a projector. In a quiet environment or for solo viewing, the speakers provide adequate volume and clarity without requiring external audio equipment. For a full cinematic experience, the projector supports Dolby Atmos and includes an eARC HDMI port for connecting a compatible soundbar to create a complete 7.1-channel surround system.

The projector can also function as a standalone Bluetooth speaker when switched to speaker-only mode, allowing music playback from phones or laptops.

Gaming Performance

When connected to a PlayStation 5, the GP520 delivers 4K 60FPS gaming with Auto Low Latency Mode (ALLM) enabled, reducing input lag for responsive gameplay. The 100-inch projection size creates an immersive gaming environment that fundamentally changes the experience compared to traditional displays. Fast-moving games like FIFA show clear field detail, and action games like Spider-Man benefit from the large screen and HDR color reproduction.

The brightness of the projector ensures that gaming content remains visible and vibrant, even in rooms with some ambient light.

3D Projection Capability

A distinctive feature of the GP520 is its 3D projection support. The projector can convert side-by-side or top-bottom 3D content into a proper 3D image when viewed with compatible 3D glasses. Premium 3D glasses are available for approximately 3,000 rupees and deliver a cinema-quality 3D experience comparable to theatrical releases.

Budget red-cyan anaglyph glasses (200 to 300 rupees) are also supported but offer significantly lower image quality. The projector supports 3D playback from Blu-ray discs if an external Blu-ray drive or PlayStation 5 disc edition is connected.

Things to Consider Before Buying

The GP520 is priced at approximately 137,990 rupees, positioning it as a premium investment. At this price point, it competes with high-end televisions and requires additional spending on a quality projection screen, mounting hardware, and potentially audio equipment to realize its full potential.

The projector performs best in darkened rooms. While it handles some ambient light better than budget projectors, a dedicated home theater environment yields the best results. The lamp requires eventual replacement, and the projector needs adequate ventilation and cooling space.

The Google TV operating system, while feature-rich, occasionally exhibits lag when navigating settings. For users accustomed to faster smart TV interfaces, this may be a minor frustration.

Buying Advice

The BenQ GP520 is best suited for viewers who prioritize a large-screen cinematic experience and are willing to invest in a complete home theater setup. It excels for movie watching, gaming, and multimedia consumption. The 3D capability adds a unique feature not found in most projectors at any price.

If you primarily watch content on streaming services and want a large display without a dedicated theater room, a high-end television might offer better practicality. However, if you value the flexibility of mounting, the immersive scale of a 100-plus-inch image, and the distinctive features like 3D support and gaming performance, the GP520 justifies its premium positioning.

Conclusion

The BenQ GP520 is a capable premium 4K projector that delivers on its promise of theater-level image quality. Its combination of native 4K resolution, HDR performance, smart features, gaming support, and 3D capability make it a comprehensive solution for home entertainment. The price is substantial, but for viewers committed to creating a dedicated home theater experience, the projector’s performance and feature set represent a meaningful investment in entertainment quality.
