The BenQ GV30 video projector features a Texas Instruments 0.23 inch DMD DLP chip (DLP230KP) that displays a definition of 1280 x 720 pixels and coupled with 300 lumens of LED illumination. The manufacturer advertises 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 has two 4 W speakers with more than respectable quality.
This model comes 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 retails 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 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 perform our measurements, we placed the video projector at 2.8 m to get an image on a 2 m base.
This model has an automatic focus and keystone adjustment system that activates 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 slightly behind a typical-sized 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 it is quite logical. In fact, this model is not designed to be used with such a large diagonal, and it is better to settle for 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 an average delta E of 4.8, above the value of 3, the threshold beyond which the eye differentiates between the desired colors and the displayed colors. The reproduction is therefore not perfect, but it remains very good for an LED projector, as all the models we tested show a colorimetric drift.
The gamma curve is stable across the 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!
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 is slightly better than the Mogo Pro, which settles for a contrast of 280:1 and a maximum brightness of 13 cd/m². Of course, we are far from living room home theater projectors, as our reference, the Sony XW5000, tops out at more than 207 cd/m² in HDR with a natural 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 layer) at 42.9ms in game mode. This results in a delay of slightly less than three frames compared to the source at 60 Hz on the screen, without being distracting. Below 50ms, the lag is still acceptable for single player games. On the other hand, competitors will go their separate ways.
Functions and ergonomics
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 acts 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 portable.
From left to right we find the camera used for autofocus, the Tof (time of flight) sensor for automatic keystone correction and finally the optical unit for image diffusion.
The BenQ GV30 also has a standard screw thread to be mounted on a very classic stand.
On top are a few buttons for turning on, controlling volume, and switching the projector to Bluetooth speaker mode, not to mention the small carrying strap and subwoofer.
The sound 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.
Connection is simplified, as 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 positioned to install the BenQ QS01 HDMI dongle. This can be replaced by an HDMI dongle with identical dimensions.
The individual remote control 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 includes an important microphone for effective research.
Coming with Android 9, the QS01 HDMI dongle has been updated to Android 10, whose interface has been overhauled to highlight content and simpler apps. It’s all quite fluid and reading the content happens without any problems. The key is certified by Google and therefore it is possible to access all 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 seconds for the Android TV system to become operational.

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 slightly regret its lack of contrast and a brightness which limits it to use in a very dark room. The idea of the HDMI dongle hidden inside is a plus when it comes to expandability. We still would 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 levels than those measured on its direct competitors.
