BenQ GV30 test: a compact and original led video projector under Android TV

The BenQ GV30 video projector has a Texas Instruments 0.23 inch DMD DLP chip (DLP230KP) that shows a definition of 1280 x 720 pixels and is accompanied by 300 lumens LED light. The manufacturer announces a life of 20,000 hours with normal light and 30,000 hours in eco mode, which is two to three times longer than models with an ultra high pressure lamp. This projector also has two 4 W speakers with more than respectable quality.

This model is provided with a BenQ QS01 HDMI stick, a clone of the Inspiron D3000 Ultra HD HDMI Stick, which fits perfectly on the side of the projector. We found Android TV 10 powered by Amlogic S905Y2 Cortex-A53 quad-core processor, 2 GB of RAM and 16 GB of storage space. It also has wifi 802.11 a/b/g/n/ac and Bluetooth 4.2 LE.

The BenQ GV30 is sold for around €600 and competes directly with the XGIMI Mogo Pro, a more compact 1080p 300 lumens model with Android TV, but less upgradeable.

2D image quality

The BenQ GV30 is equipped with fixed focal length optics to project a basic image between 80 cm and 2.60 m for a recoil between 1 m and 3 m. To make our measurements, we placed the video projector at 2.8 m to get an image of 2 m base.

This model has an automatic focus and keystone adjustment system that is activated when the projector is moved. This system is very efficient and works at an angle of 135 °. The accuracy of the DLP230KP 720p chip is behind a typical size projector such as a BenQ W1090 with a 0.65 inch DLP DarkChip 3 chip, or even an XGIMI H2 with a 0.47 inch DLP Full chip. HD, but that makes sense. In fact, this model is not designed to be used with such a large diagonal and is better content with a basic image of 1.4 m with a setback of 2 m. The resolution is then more acceptable.

Delta E = 4.8

In Cinema mode, we measured the average delta E of 4.8, above the value of 3, the threshold beyond which the eye makes the difference between the colors requested and the colors displayed. So the rendering is not perfect, but it remains very good for a led projector because all the models we tested showed a colorimetric drift.

The gamma curve is stable throughout the spectrum and the average of 2.11 is close to the reference value (2.2). The gray levels are thus very well done.

The temperature curve is completely stable throughout the spectrum and the average temperature measured at 6850 K is very close to the reference value (6500 K). The finish is just perfect!

The contrast ratio of 430:1 (of our 1% white target) is low and does not allow us to enjoy perfect blacks. This value falls to 180:1 in our target with 35% white. The maximum brightness is also limited with a maximum value of 19 cd/m². So this model is only used in a dark room. It is a little better than the Mogo Pro, which is content with a contrast of 280:1 and a maximum brightness of 13 cd/m². Of course, we are far from the fault of Home Cinema projectors since our reference, the Sony XW5000, rises to more than 207 cd / m² in HDR with a native contrast of 1890:1.

The BenQ GV30 uses three diodes (red, green and blue) to reproduce the image, and like all mono-DLP projectors, the rainbow effect is present. This phenomenon is more or less visible, depending on the people and the images. This results in small rainbows around bright objects on dark backgrounds.

We measured the display delay (input lag) in 42.9 ms in game mode. This results in a delay of slightly less than three frames compared to the source of 60 Hz. on the screen, without interrupting. Under 50ms, the lag is still acceptable for single-player games. On the other hand, the competitors will go their way.

Functions and ergonomics

The design of the BenQ GV30 is original, all round. The white matte plastic looks quality and the assembly is good.

The magnetic foot.

The magnetic foot serves as a support for the video projector. It allows you to adjust the tilt up to 135 °, but it is very heavy, which makes the projector not very portable.

The fixed focal length optics as well as the camera for focusing and the Tof sensor for keystone correction.

From left to right, we see the camera used for autofocus, the Tof (time of flight) sensor used for automatic keystone correction and, finally, the optical unit for image diffusion.

A screw step.

The BenQ GV30 also has a standard screw thread to mount on a classic tripod.

A few buttons and a carrying handle.

On top, there are some buttons for powering, volume control and switching the projector to Bluetooth speaker mode, not to mention the small carrying strap and the subwoofer.

The 2.1 audio system.

Audio quality is also good for a projector of this size. It can clearly replace a small Bluetooth speaker thanks to these two 4 W speakers and its subwoofer.

The connection.

The connection is simplified because you need to do an HDMI 1.4 input, a USB-C input (USB and DisplayPort) and a 3.5 mm mini-jack headphone output. The device also has Bluetooth 4.2.

Under the cover on the left side, there is an HDMI 1.4 input and a microUSB connector perfectly placed to install the BenQ QS01 HDMI key. It can be replaced with an HDMI key with the same dimensions.

Remote control with microphone.

Remote control with microphone.

A remote control allows you to control the projector and the Android TV system. Some buttons provide access to projector functions such as keystone adjustment or source selection, while others are dedicated to Android TV (home button, Amazon Prime Video, Google Assistant). This remote control also includes an essential microphone for effective research.

Android TV 10.0 interface.

Android TV 10.0 interface.

Delivered on Android 9, the QS01 HDMI key has been updated to Android 10, whose interface has been changed to highlight content and simpler apps. The whole is quite fluid and reading the contents is done without any problem. The key is verified by Google and therefore it is possible to access all the apps from the Google Play Store, except… Netflix which is strangely not in the store on this model. Other applications such as Amazon Prime Video, YouTube, Disney+ or MyCanal are available and work without problems. If the video projector starts up quickly thanks to its LEDs, it will take about 37 s before the Android TV system can be used.

Strong points

  • Image quality.

  • Built-in Android TV and Google Assistant.

  • Native access to French streaming apps (MyCanal, Molotov, RMC, MyTF1, OCS, etc.).

  • Automatic focus and keystone correction by camera.

  • Loud audio system.

  • Remote control using the microphone.

  • Consumption.

How does grading work?

The BenQ GV30 is a great little video projector, not really portable, but easy to carry, which provides a well-calibrated image and above all quality sound, which is rare for this type of device. . We regret a little the lack of contrast and brightness that limits it to use in a dark room. The idea of ​​an HDMI key hidden inside is a plus when it comes to expansion. We would have appreciated the presence of Netflix in addition to other video streaming applications, but overall the experience remains very good. However, this model lost its fourth star due to higher noise levels than those measured by its direct competitors.
