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) displaying a definition of 1280 x 720 pixels and coupled with 300 lumens LED lighting. The manufacturer announces a lifespan of 20,000 hours with normal brightness and 30,000 hours in eco mode, which is two to three times longer than models equipped with an ultra high pressure lamp. This projector also features two 4 W speakers with more than respectable quality.

This model is supplied 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 find Android TV 10 powered by an 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 lumen model that also has Android TV, but is less upgradable.

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 carry out our measurements, we placed the video projector at 2.8 m in order to obtain an image of 2 m base.

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

Colorimetry

Delta E = 4.8

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

2.11

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

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

Contrast

Contrast

Editor's Rating: 2 out of 5

430:1

The contrast ratio of 430:1 (on our 1% white target) is low and does not allow us to enjoy perfect blacks. This value drops to 180:1 on our target containing 35% white. The maximum brightness is also limited with a maximum value of 19 cd/m². This model is therefore only used in a darkened room. It’s 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 a long way from living room Home Cinema projectors since our reference, the Sony XW5000, peaks at 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, if at all depending on the people and the images. It results in small rainbows around bright objects on a dark background.

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

Functions and ergonomics

The BenQ GV30 projector.

The design of the BenQ GV30 is original, all in roundness. The off-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 quite heavy, which makes the projector a little less transportable.

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

From left to right, we find 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 be mounted on a very classic tripod.

A few buttons and the carrying handle.

A few buttons and the carrying handle.

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

The 2.1 audio system.

The audio quality is also very 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 since you have to make do with 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. This can be replaced by an HDMI key with identical dimensions.

The remote control with microphone.

The remote control with microphone.

The single remote allows you to control both 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 incorporates a microphone essential for effective research.

Android TV 10.0 interface.

Android TV 10.0 interface.

Delivered with Android 9, the QS01 HDMI key has been updated to Android 10, whose interface has been revised to highlight content and more simply apps. The whole is quite fluid and the reading of the contents is done without problem. The key is certified by Google and it is therefore possible to access all the apps from the Google Play Store, except… Netflix which is surprisingly absent from the store on this model. Other applications such as Amazon Prime Video, YouTube, Disney+ or MyCanal are present and work without problems. If the video projector starts instantly thanks to its LEDs, it still takes about 37 s before the Android TV system becomes operational.

Strong points

  • Image quality.

  • Built-in Android TV and Google Assistant.

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

  • Automatic focusing and keystone correction by camera.

  • Powerful audio system.

  • Remote control with microphone.

  • Consumption.

Weak points

  • Limited contrast.

  • Removable base not really practical.

  • Low light.

  • Not really silent.

  • No backlight on the remote control.

Conclusion

Global mark

How does grading work?

The BenQ GV30 is a good little video projector, not really portable, but easily transportable, which delivers a well-calibrated image and above all quality sound, which is rare on this type of device. We regret a little its lack of contrast and a brightness which limits it to use in a very dark room. The idea of ​​the HDMI key hidden inside is a plus in terms of expandability. We would still have appreciated the presence of Netflix in addition to the other video streaming applications, but overall the experience remains very good. However, this model loses its fourth star due to higher noise than those measured on its direct competitors.
