The BenQ GV30 video projector has a 0.23-inch DMD DLP chip from Texas Instruments (DLP230KP) that displays 1280 x 720 pixel definition and is paired with 300 lumen LED lighting. The manufacturer advertises a lifespan of 20,000 hours in 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 4W speakers with more than respectable quality.
This model ships with a BenQ QS01 HDMI stick, a clone of the Inspiron D3000 Ultra HD HDMI Stick, which fits neatly into 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 Wi-Fi 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 upgradable.
2D image quality
The BenQ GV30 is equipped with fixed focal length optics to project a basic image between 80cm and 2.60m for a throwback of between 1m and 3m. To carry out our measurements, we placed the video projector at 2.8 m to obtain an image with a base of 2 m.
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 accuracy of the DLP230KP 720p chip falls a bit short of 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 Full HD DLP chip, but that is quite 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.
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 requested colors and displayed colors. So the rendering isn’t perfect, but it’s still very good for an LED projector, as all the models we tested show colorimetric drift.
The gamma curve is stable throughout the spectrum and the average of 2.11 is quite close to the reference value (2.2). Gray levels are very well reproduced.
The temperature curve is perfectly 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 (at our target of 1% white) is low and does not allow us to enjoy perfect blacks. This value drops to 180:1 on our lens which contains 35% white. The maximum brightness is also limited with a maximum value of 19 cd/m². Therefore, this model is only used in a dark room. It is slightly better than the Mogo Pro, which is content with a contrast ratio 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, reaches peaks of 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. Results in little rainbows around bright objects on a dark background.
We measure the display delay (input lag) to 42.9 ms in game mode. This results in a delay of just under three frames compared to the 60Hz source on screen, without being distracting. Below 50ms, the lag is still acceptable for single player games. On the other hand, competitors will go their way.
Functions and ergonomics
The design of the BenQ GV30 is original, all in roundness. The off-white matte plastic looks quality and the build is good.
The magnetic foot serves as a support for the 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 used for automatic keystone correction, and lastly, the optical unit for image diffusion.
The BenQ GV30 also has a standard screw thread to be mounted on a very classic tripod.
At the top, there are a few buttons for power, volume control, and switching the projector to Bluetooth speaker mode, not to mention the little carrying strap and subwoofer.
Audio quality is also very good for a projector of this size. It can clearly replace a small Bluetooth speaker thanks to these two 4W speakers and their 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 3.5mm 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 perfectly placed microUSB connector to install the BenQ QS01 HDMI dongle. This can be replaced by an HDMI key of identical dimensions.
Single remote control allows you to control both the projector and Android TV system. Some buttons provide access to projector features 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 an effective investigation.
Delivered with Android 9, the QS01 HDMI dongle has been upgraded to Android 10, whose interface has been revised to highlight simpler content and apps. The whole is quite fluid and the reading of the contents is carried out without any problem. The key is certified by Google and therefore it is possible to access all the applications of the Google Play Store, except… Netflix, which is surprisingly absent from the store in 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, the Android TV system takes about 37 seconds to be operational.

How does the rating work?
The BenQ GV30 is a good little video projector, not really portable, but easily transportable, offering a well-calibrated image and, above all, quality sound, something unusual in this type of device. We do regret a bit its lack of contrast and a brightness that limits its use in a very dark room. The idea of the HDMI key hidden inside is a plus in terms of expandability. We still would have appreciated the presence of Netflix in addition to the other video streaming apps, but overall the experience is still very good. However, this model loses its fourth star due to a noise higher than that measured on its direct competitors.
