BenQ W1800i test: an Ultra HD Android TV projector finally well calibrated

The BenQ W1800i video projector has a Texas Instruments 0.47 inch DMD (DLP470TE) DLP chip that displays native Ultra HD definition at 3840 x 2160 pixels. As a reminder, this generation uses wobulation (faster display of multiple Full HD images offset from each other) at 240 Hz to broadcast four Full HD images that side by side, and thus produce an Ultra HD 60 Hz image of 8.3 million actual pixels.

The chip is equipped with an ultra high pressure (UHP) lamp that delivers 2000 lumens. The manufacturer claims a life of 4,000 hours with maximum brightness (normal) and 15,000 hours in Lamp Save mode. This is lower than models that use LEDs as a light source with a duration of more than 20,000 hours. This projector also has a 5 W speaker which is just enough to watch short videos.

This model is supplied with a BenQ QS01 HDMI stick (clone of the Inspiron D3000 Ultra HD HDMI Stick) that fits perfectly on the back of the projector. We found the 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.

Featuring an Ultra HD definition, the BenQ W1800i is reasonably expensive as it sells for almost € 1300, but can sometimes be found for less than € 1100. However, it remains one of the most readily available. Ultra HD Android TV models on the market. For comparison, the XGIMI Horizon Pro retails for almost € 1700 and the laser models are more expensive. The Vava 4K UST Laser Projector, with a more powerful laser and ultra-short focal length, sells for about € 2,700, while the Samsung The Premiere LSP9T and the Sony VPL-VW290ES reference are both shown for more than € 4,000, the latter also without an intelligent system.

2D image quality

The BenQ W1800i is equipped with a 1.3x optical zoom to project a standard image between 2 m and 2.60 m for a recoil of 3 m. To make our measurements, we set ourselves at 3 m and adjust the optical zoom to a minimum to get an image of 2 m base. This model also offers adjustment of shift the lens vertical by ± 3% slightly corrects to place the image without distortion. The Full HD display is sharp, even at corners, a little less sharp than Ultra HD due to the wobulation process. As is the case with all Ultra HD projector models with a DLP chip, light artifacts around objects remain visible.

Delta E = 1.8

In Filmmaker mode, the BenQ W1800i is fully calibrated and thus displays colors faithful to that sent by the source. We measured the average delta E at 1.8, well below the value of 3, a floor below where the eye can no longer tell the difference between good colors and the colors shown. Some shades show a drift higher than 3, but overall the result is very good.

The gamma curve is strong across the spectrum and the average of 2.2 is set by the reference value (2.2). The gray levels are thus perfectly rendered in the image.

The temperature curve is completely stable across the spectrum and the average temperature measured at 6760 K is very close to the reference value (6500 K). The finish is just perfect!

720: 1

The contrast ratio of 720: 1 (on our 1% white chart) remained below perfect term and did not allow us to enjoy perfect blacks. This amount fell to 220: 1 of our target with 35% white. The maximum brightness is very good at 124 cd / m², which allows for a nearly dynamic HDR rendering, but video projectors still obviously have a handicap at this point because they can’t handle the local brightness of the image. In comparison, our Sony VW290ES benchmark peaks at 167 cd/m² with a native contrast of 2820: 1, but all Ultra HD models suffer from contrast deficit, even more so compared to DLP Full HD ones. model. You need to look at DLP Ultra HD models using a laser, such as the VAVA 4K UST Laser or the Samsung The Premiere LSP9T, to see a difference of more than 1200: 1.

The BenQ W1800i uses a six -part color wheel to minimize the rainbow effect. This phenomenon is visible on all projectors using a DLP chip, and it is more or less visible, depending on the people and the images. This results in small rainbows around bright objects on a dark background.

The W1800i has a display delay (input lag) at 33 ms in standard mode, but this can drop to 17 ms if “fast mode” is activated. This results in a delay of approximately one frame compared to the source at 60 Hz. There is no delay between the action performed with the controller and its repercussion on the screen.

Delta E = 7.6

Correctly interpret HDR as transcendent. With its slight difference, the BenQ W1800i has little trouble handling low light well at the starting curve. The maximum brightness of 117 cd / m² remains a good average for a video projector, but does not compete with televisions (750 cd / m² for Oled TVs and even more than 1500 cd / m² for most very LCDs). Finally, we have a somewhat reduced image dynamics that do not allow the HDR content to express itself fully. It remains acceptable, but the HDR level is very far from what would be possible with more contrast and brighter projectors, such as the VAVA 4K UST Laser or the Sony VW290ES mentioned above.

The BenQ W1800i looks like a very classic video projector … Almost disappointed in 2022. Aside from the bronze-colored front, this model looks like a video projector with white plastic. office. In this photo, we can see the infrared receiver on the front to facilitate controls via remote control, as well as adjustable feet to straighten the plate and the trapezoid in the image.

The connection.

The connection is even lighter as it consists of two HDMI 2.0b inputs, a 3.5 mm mini-jack audio output, a USB port that allows a 15 W (1.5 A) power supply and an RS -232 ports to facilitate integration in a home automation. system.

Once the screw is removed, the cover will give way to a third HDMI 2.0b input and a microUSB connector that is fully inserted to install the BenQ QS01 HDMI key. It’s also possible to insert a key into the Amazon Fire TV Stick HDMI, for example, but you’ll need to use two remote controls.

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.

The Android TV 10.0 interface

The Android TV 10.0 interface

Delivered with Android 9, the QS01 HDMI key has been updated to Android 10, whose interface has been redesigned to highlight content and more simple applications. Everything is pretty fluid and reading the inside in Ultra HD is no problem. The key is verified by Google and therefore it is possible to access all apps from the Google Play Store, except for… Netflix which is strangely not in the store on this model. Other applications are available and display Ultra HD HDR content, such as Amazon Prime Video, YouTube, Disney+ or MyCanal. The weak point remains the ignition time because it takes more than a minute to operate the whole thing: the time for the Android TV system to fully launch and, most of all, for the UHP heating lamp. .
