Never before has home entertainment been so exciting. From massive OLED TVs to ultra-short throw projectors, consumers today have more ways than ever to bring the cinema home. But of all the choices, few products manage to combine cutting-edge image quality, convenient wireless connectivity, and long-lasting reliability like BenQ GP520 3D 4K Projector.
Marketed as a premium 3D 4K LED projector, the GP520 attempts to give the ultimate all-in-one experience: crisp visuals, intelligent streaming, and seamless control. While most reviews focus on its 4K HDR performance, today we’ll take a deeper look at four elements that define its real-world usability: remote control, connectivity options, storage capability, and lens performance.
Whether one is a movie enthusiast, gamer, or professional in search of a do-it-all projector, this review will show how well the BenQ GP520 fares on each of these points.
Design and Build of BenQ GP520 3D 4K Projector: Compact Elegance for Modern Spaces
Over the years, BenQ’s design language has matured rather beautifully. The GP520 continues that tradition with an understated yet elegant form factor. It’s compact enough to fit on a side table but sturdy enough to feel like a professional-grade device.
The chassis is finished in matte white with a premium gold-accented ring around the lens, a subtle detail that instantly separates it from budget models. The ventilation layout keeps the heat under control without ruining the aesthetics, and the port panel is neatly arranged on the rear.
With a weight of about 4.5 kg and a size of approximately 360 × 260 × 135 mm, it is portable yet solid. You could easily move it out from a living room setup to a backyard movie night without much hassle.
Every aspect of the GP520’s design speaks to attention to detail, and that thoughtfulness carries over into its control system, storage structure, and optical precision.
Remote Control in BenQ GP520 3D 4K Projector: Simple, Smart, and Surprisingly Powerful
A great projector is only as enjoyable as the ease with which you can control it. BenQ clearly gets that, because the GP520 remote is one of the best in its class.
Ergonomic Feel
It’s slim, lightweight, and slightly curved to comfortably fit into your hand. The buttons are soft-touch but tactile; the matte finish keeps fingerprints and smudges at bay. The layout is logical: power and input at the top, navigation in the center, and streaming shortcuts below.
Voice and Smart Control
Thanks to integration with Google TV, the remote incorporates a dedicated Google Assistant microphone. Hold down the mic button, and you can control almost everything by voice:
- “Play Oppenheimer on Netflix.”
- “Switch to HDMI 2.”
- “Open YouTube.”
- “Turn brightness to Eco mode.”
Fast, accurate, and no need for manual typing: this is finally what projector owners have been looking forward to.
Wireless Connectivity
Unlike old IR remotes that require line-of-sight, the GP520 remote uses Bluetooth Low Energy. You can control the projector even if it’s behind you or mounted on the ceiling. It pairs instantly during setup and stays connected reliably without noticeable lag.
Shortcut Keys
BenQ adds dedicated buttons for Netflix, Prime Video, and YouTube, plus a customizable shortcut to which you can assign any app or setting. It’s one of those inclusions that just makes sense for users who rely on streaming platforms so much.
Taken altogether, the GP520 remote takes an interaction that’s traditionally clunky and makes it smooth, modern, and intuitive: a major win for everyday usability.
Connectivity in BenQ GP520 3D 4K Projector: The Heart of a Smart Projector
Connectivity defines how flexible a projector is in the real world, and here the BenQ GP520 excels: it’s built to connect with nearly anything you own, both wired and wirelessly.
Comprehensive Port Selection
- On the back panel, you will find 2 × HDMI 2.0 ports (one supports eARC/ARC for audio return)
- 2 × USB Type-A ports for external drives or dongles
- 3.5 mm audio out
- Optical S/PDIF output for hi-fi sound systems
- LAN (Ethernet) port for stable wired Internet
And that’s more than enough for simultaneous use by consoles, laptops, set-top boxes, and soundbars.
Wireless Performance the Ultimate Home Entertainment
The one place where the GP520 really feels next-generation is in its wireless connectivity: Wi-Fi 6 (dual-band 2.4 GHz + 5 GHz) and Bluetooth 5.2 make easy work of 4K streaming and device pairing.
Wi-Fi 6 ensures smoother streaming with reduced buffering, even on busy networks. Bluetooth 5.2 allows you to connect your wireless headphones, speakers, or game controllers directly.
Casting and Screen Mirroring
GP520 comes with Chromecast built-in and support for Apple AirPlay, meaning you can mirror Android, iPhone, iPad, or Windows laptops in mere seconds. No additional dongles or applications are needed; the projector will automatically appear as a casting device.
This flexibility means that whether you’re presenting a slideshow from your laptop, streaming a YouTube playlist from your phone, or casting Netflix from a tablet, the GP520 makes it frictionless.
Latency and Input Response
Input lag for gamers sits at around 17.9 ms at 4K 60 Hz, which is remarkable for an LED projector. Though it does lack 120 Hz refresh rates, casual and console gaming feels responsive and smooth.
In short, the connectivity on the BenQ GP520 isn’t just comprehensive; it’s future-proof. It provides a combination of versatility and performance that makes it equally at home in entertainment centers, offices, or classrooms.
Storage and System Performance of BenQ GP520 3D 4K Projector: Compact but Capable
The GP520 doesn’t rely on outside devices for smart functionality; instead, it’s a fully integrated Google TV projector running Android 12 TV out of the box.
Internal Storage in BenQ GP520 3D 4K Projector
It comes with 16 GB of internal storage; about 10 GB is available to users after system files take their share. That’s enough to install all your favorite apps—Netflix, Disney+, Prime Video, YouTube, and Spotify—and still have some room for cached data.
While you won’t be storing massive movie files internally, it’s perfect for app data and small media collections.
Expandable Storage in BenQ GP520 3D 4K Projector
The projector supports up to 2 TB USB flash drives or external SSDs. Plug one into the rear port, and the GP520 automatically recognizes and indexes your files. It supports major formats such as MP4, MKV, AVI, MOV, MP3, JPEG, and PNG, so you can play videos, photos, or music directly.
Processing Power of BenQ GP520 3D 4K Projector
Under the hood is a quad-core ARM Cortex-A55 CPU with 2 GB RAM. Combined with BenQ’s software optimization, the interface runs smoothly. Switching between apps, adjusting settings, or browsing streaming libraries happens almost instantly—a noticeable improvement over older Android TV projectors.
System Responsiveness of BenQ GP520 3D 4K Projector
Due to the deep integration of Google TV, the GP520 also gets automatic updates, voice search, and personalized recommendations. The performance is the same even after playing for hours continuously.
This smart, storage-efficient system design lets the GP520 operate as a standalone streaming device: no need for any Fire Stick or Chromecast.
Lens and Optical Performance in BenQ GP520 3D 4K Projector: The Core of Visual Excellence
Now, for the thing that makes or breaks any projector: its lens system.
True 4K Clarity
Native 4K UHD (3840 × 2160) resolution from the GP520 is realized by high-precision DLP technology—not pixel-shifting. Textures, fine details, and subtitles appear razor-sharp, even on large 120-inch screens.
Every element of the optical system is made from multi-coated glass to ensure minimal chromatic aberration and distortion. The result is an image that stays consistent from center to corner, an area where cheaper projectors often struggle.
4 LED Light Engine
BenQ’s 4LED light source replaces the traditional lamp with four high-efficiency LEDs. It boosts brightness to 2,600 ANSI lumens while extending lifespan to up to 30,000 hours in Eco mode.
- Color accuracy is excellent:
- 98% Rec. 709 coverage for vivid, yet realistic tones
- 81% DCI-P3 gamut for HDR content
That means movies look cinematic without oversaturation, which plagues many consumer projectors.
Auto Focus and Keystone
Setup is easy. The GP520 focuses automatically and corrects keystone distortion (vertical ±30°, horizontal ±30°). You can even place it at an angle, and the image snaps to perfect alignment in a matter of seconds.
Throw Ratio and Zoom
The zoom is 1.2×, while the throw ratio is 1.21–1.59. You can get a 100-inch image from about 2.5 m, with good flexibility in placement, whether in a cozy living room or a more dedicated home theater.
Image Quality in Real Use
When streaming 4K HDR titles, images through the GP520’s lens are crisp and luminous. Bright scenes pop with clarity, and shadow detail remains strong. Though black levels aren’t as deep as laser projectors, the overall contrast is impressive for its price bracket.
Fast motion scenes show minimal blur, and the fine lines in animation movies or subtitles are clearly distinguishable. Color uniformity is also quite good: no vignetting, no edge fade.
Combined, the LED engine and optical precision make the GP520’s lens one of the best in its category, balancing brightness, color, and long-term durability.
Everyday Experience of BenQ GP520 3D 4K Projector: Seamless Integration of All Four Pillars
What really sets the BenQ GP520 apart, however, is how these four systems—remote, connectivity, storage, and lens—operate in perfect harmony.
You pick up the Bluetooth remote and speak into the mic to open Netflix, stream a 4K HDR movie through Wi-Fi 6, and within an instant, the projector outputs a crystal-clear image through its precision lens. Audio is routed wirelessly to your Bluetooth soundbar, and it plays back smoothly.
No juggling with cables, no delay, and no headache with setup. It’s this seamless integration that takes the GP520 from good to a truly premium projector.
Performance and Reliability in India
In various countries, like India, where the environmental light and access to service may be problematic, the GP520 performs well. Its output of 2,600 lumens is enough for semi-lit rooms, while its light source is LED; hence, there is no need for bulb replacement.
BenQ’s service network covers major cities in India, and buying from authorized dealers will ensure warranty coverage. Connectivity features like Ethernet and dual-band Wi-Fi make it fit for Indian households with varying internet conditions.
