Applications: what the BenQ GP520 is ideal for

Movie and series nights in the living room

With 2,600 lumens and Google TV, the GP520 delivers a convincing picture for evening viewing in the living room – even when a little ambient light is still coming through the windows. HDR10+ adapts tone mapping scene by scene to the projector's capabilities, so highlights and shadows look much more nuanced than with static HDR10. Netflix, Amazon Prime Video and Disney+ run directly via the Google TV interface, without an external player.

Gaming with automatic latency optimisation

ALLM (Auto Low Latency Mode) detects as soon as a games console sends a signal and automatically switches the projector to its optimised game mode – no manual switching needed. The HDMI 2.1 interface provides the bandwidth needed for modern consoles. If you need the lowest possible response time, position the projector physically correctly and avoid digital keystone correction: keystone processing increases signal delay by several milliseconds.

Smart home cinema without installation hassle

The GP520's autofocus sharpens the image automatically after switching on, and automatic 2D keystone correction compensates for vertical placement deviations – the system also corrects for obstacles in the image area. The compact housing (241 × 225 × 151 mm, 3.7 kg) can be placed flexibly on a coffee table, sideboard or tripod. For a permanent setup, we recommend ceiling mounting with a suitable bracket.

Picture quality

The GP520 uses DLP technology with a 0.47-inch DMD chip. Using XPR pixel shift, the chip produces 4K UHD output with 3,840 × 2,160 pixels – the native chip works with a resolution of 2,560 × 1,200 pixels and shifts these rapidly to display all 4K pixels. For most seating distances and image sizes from 100 inches, this difference from native 4K is not noticeable during normal film viewing. With 2,600 lumens, the GP520 is suitable for darkened rooms and living room evenings with ambient light; for full daylight use, we recommend models with 3,500 lumens or more.

HDR10+ supports dynamic metadata that controls tone mapping scene by scene. The contrast ratio of 200,000:1 describes the system's dynamic value; DLP projectors in this class deliver strong black levels in normal operation that impress in darkened rooms. The LED light source produces a naturally wide colour gamut without colour wheel artefacts, as no rotating colour wheel is used.

Moving images are displayed without dedicated frame interpolation – for classic film productions at 24 fps, this is the most natural approach, as there is no soap opera effect. 3D playback is possible via DLP Link (compatible 3D glasses required, not included).

Connections:

• 2× HDMI 2.1 (HDCP 2.2) – one with eARC for lossless audio formats such as Dolby TrueHD or DTS-HD Master Audio to a soundbar or AV receiver; both ports support the bandwidth needed for modern consoles
• 1× USB-A (5 V / 1.2 A) and 1× USB-C (video input and optional power supply over a single cable)
• 1× audio out (3.5 mm jack)
• LAN (RJ-45): network connection and firmware updates via your home network
• Built-in Wi-Fi (for streaming, Google Cast and software updates)
• Bluetooth: wireless audio output to Bluetooth speakers or headphones

Gaming performance

ALLM (Auto Low Latency Mode) activates the optimised game mode automatically as soon as a console such as the PS5 or Xbox Series X sends a compatible signal. Maximum input signal support is 240 Hz – we recommend checking with your console or PC at which resolution this value is reached. With a physically correctly aligned projector, signal delay remains at the native level of the processing chip. If you also need variable refresh rates (VRR), our gaming projectors include specialised models with FreeSync or G-Sync support.

Sound

The GP520 features an integrated 2 × 12 W stereo speaker system (24 W in total). This is sufficient for spontaneous movie nights and everyday use. If you want the full cinema experience, use the eARC output (HDMI) for a soundbar or AV receiver: eARC transmits lossless formats such as Dolby TrueHD or DTS-HD Master Audio uncompressed. Alternatively, the GP520 connects via Bluetooth to wireless speakers or headphones – handy for late-night movies without cables.

Smart features & streaming

The BenQ GP520 runs on Google TV – the current generation of Google's operating system with a personalised home screen, unified search across all streaming services and the full Google Play Store. Netflix, Disney+, YouTube, Amazon Prime Video and other services are pre-installed or can be added via app; there is no need for a separate streaming stick. Google Assistant responds to voice commands via the remote control.

Google Cast (Chromecast built-in) lets you stream content wirelessly from Cast-enabled apps on your smartphone directly to the projector – your smartphone is not burdened, as the projector fetches the stream from the internet itself. Wi-Fi and LAN enable a stable network connection; for 4K streaming, we recommend the 5 GHz Wi-Fi band or a direct LAN connection.

Setup, projection & scope of delivery

The GP520's fixed lens has a fixed throw ratio of 1.2:1 – the distance to the screen directly determines the image size. Autofocus and automatic 2D keystone correction (vertical, up to ±40° horizontal) ensure that the image is quickly aligned correctly after switching on. For distortion-free projection, the projector should be aimed as directly as possible at the centre of the image. Models with optical lens shift offer additional flexibility for asymmetrical placement.

Add a further approx. 10–15 cm to the housing depth of 22.5 cm for cable connections at the rear.

For rooms with ambient light, an ALR (ambient light rejecting) screen is worthwhile, as it blocks stray light from the side and increases contrast even when the room is not fully darkened. In a darkened home cinema, a classic gain 1.0 screen delivers the best colour reproduction.

Light source & operation

The GP520's LED light source is maintenance-free and reaches full brightness immediately after switching on – with no warm-up time. In normal operation, it lasts up to 20,000 hours; with a three-hour movie night every day, that equates to around 18.5 years. In Eco mode, power consumption and noise levels fall, and service life increases to up to 30,000 hours.

Power consumption: 186 W in normal operation, 0.5 W in standby. Eco mode noticeably reduces power consumption and operating noise.

Operating noise is 26 dB in normal mode and 24 dB in Eco mode – comparable to the noise level of a quiet library or a softly ticking alarm clock. The fan may be audible in quiet film scenes; in Eco mode, the GP520 remains virtually inaudible even in quiet passages.

Target groups at a glance

• Streaming fans looking for an all-in-one solution: If you want to launch Netflix, Disney+ and the like directly on the projector, the GP520 gives you a fully fledged Google TV platform – all apps on one device, no separate player required.
• Living room home cinema with flexible placement: Autofocus and automatic keystone correction make the GP520 a hassle-free companion for evening viewing – quick to set up and ready to go instantly.
• Casual gamers: ALLM and HDMI 2.1 automatically optimise latency with consoles; if you play competitively and rely on VRR or very low input lag, our gaming projectors include specialised models.
• Choosing LED instead of a lamp: 20,000 h of maintenance-free service life – the light source lasts for the projector's entire life, with no follow-up costs for replacement lamps.

When an upgrade is worthwhile

• More brightness for bright rooms: If you also use the projector during the day with some daylight, you will find more light reserve in our home cinema projectors with 3,500 lumens or more .
• Optical lens shift for flexible placement: Models with lens shift allow optical image shifting without loss of resolution – ideal for asymmetrical shelf or ceiling positions.
• Laser instead of LED for maximum long-term stability: Laser projectors offer an even longer service life, higher contrast and a more stable colour gamut over their entire operating life.

Have you thought of everything?

• Screen: For a permanent home cinema setup, a fixed-frame screen with maximum flatness is ideal; a motorised screen, which disappears when not in use, is more flexible. For rooms with ambient light, we recommend an ALR screen from our ambient light rejecting screens.
• Ceiling mount: For a permanent installation, we recommend a suitable projector ceiling mount; the GP520 then hangs upside down and the projector flips the image automatically.
• HDMI cable: No HDMI cable is included – an HDMI cable is part of the basic equipment. For ceiling mounting or distances over 3 m, we recommend an active or certified Ultra High Speed HDMI cable from our HDMI cable range.
• Sound upgrade: The integrated 2 × 12 W speakers allow direct operation; for room-filling home cinema sound, consider a soundbar or a home cinema system , connected via eARC or Bluetooth.
• Tripod: For flexible placement without drilling, we recommend a projector tripod.

Conclusion
