BenQ W2720i Review: Does This Android TV Back-Room Projector Measure Up?

May 21, 2025

Test du BenQ W2720i : ce vidéoprojecteur « fond de salle » sous Android TV a-t-il tout d’un grand ?
The BenQ W2720i offers an Ultra HD LED Home Cinema experience that is both accessible and versatile, suitable for both film enthusiasts and demanding gamers. We tested this model which relies on proven technology and a comprehensive set of connections, while integrating Android TV. Here’s our verdict.

The BenQ W2720i follows in the footsteps of traditional Home Cinema projectors, featuring a 4-LED light source, Ultra HD resolution simulated by XPR technology, and nearly complete HDR compatibility (HDR10, HDR10+, HLG) – only lacking Dolby Vision. Against its competitors, it stands as a credible alternative to triple-laser or UHP lamp models, focusing on color accuracy, ease of installation, and versatility that ranges from home cinema to gaming.

At approximately 1,990 euros, it targets discerning users who want a no-compromise home cinema experience with precision in color accuracy, fluidity, and connectivity. Compared to models like the Hisense C2 Pro or BenQ GP520, which are more compact, the W2720i opts for a traditional setup, placed at the back of the room similar to the Optoma UHZ68LV. Compared to the latter, which is Dolby Vision certified and more expensive, it incorporates Android TV (via a dongle). Lastly, it features reduced input lag for gaming.

BenQ W2720iTesting Conditions

The BenQ W2720i projector we tested was loaned to us by the brand. It was tested in conjunction with a Lumene Movie Palace UHD Platinum 300C screen, a model specifically designed for Home Cinema projectors. Measurements were made with professional equipment directly in front of the screen to minimize errors and provide values that reflect what the viewer can actually see. This protocol is identical for all projector tests to enable comparison.

BenQ W2720iDesign, A Relatively Compact Model for Back of Room Placement

The BenQ W2720i features a classic and relatively bulky design, but it is also much more compact than models like the Optoma UHZ68LV or the Sony VPL-XW5000ES and its siblings, for example.

It is primarily designed for fixed installation, ideally on the ceiling in a dedicated room. Its black chassis is simple and elegant, contrasting with the disruptive designs of lifestyle or ultra-short throw models. It features a partial covering with a faux leather texture, giving it a certain class.

At the front, the lens is centrally positioned to facilitate alignment with the screen, adhering to the standards of professional projectors.

The materials used are robust, with a well-finished facade and discreet side vents. The generous dimensions (420 x 143 x 305 mm for 6.4 kg) indicate a desire to offer quality optics and effective thermal management.

The optical block, composed of ten lenses arranged in six groups, ensures good sharpness across the entire image surface. The design prioritizes functionality over flashiness, with adjustable feet for table placement and fittings for ceiling installation.

Indeed, underneath, there are 4 pads for placing the projector on a shelf. Alternatively, there are several screw holes for fixing it to a support in case of ceiling placement. Everything is provided for perfect integration in the living room or dedicated room.

On the top, there is a small trap door that closes hiding the dial for manually adjusting the zoom and the ring for focusing. Similar to Epson projectors, the operation is efficient and quick.

It is also on the top, after removing a part that slides, that we find the location for the Android QS02 dongle. It is directly powered and there is an HDMI cable to connect it.

On the side, there are several buttons that allow control of several functions of the device and navigation through the menus. This is handy if the remote control is unavailable.

On the test model provided by the brand, we appreciated the neat finish, without frills. This design choice aims to reassure users looking for a reliable device, designed to last and integrate into a home cinema environment.

BenQ W2720iConnectivity, Everything You Need

The W2720i offers rich and well-thought-out connectivity. At the back, there are two HDMI 2.1 inputs, one of which supports eARC for audio return to a soundbar or amplifier, as well as an additional HDMI 2.0b.

This setup allows for the simultaneous connection of multiple sources, such as a Blu-ray player, a game console, and a media box, without having to juggle cables. Two USB-A ports are present, one for multimedia content playback, the other for firmware updates or powering accessories.

An optical S/PDIF audio output and a stereo Jack output offer solutions for connecting an external audio system. The presence of an RJ45 Ethernet port completes the network connectivity, in addition to the integrated Wi-Fi 5.0 and Bluetooth 5.0. As a hallmark of well-thought-out models and practical for perfect integration within a complete Home Cinema system, a 12V trigger port allows for controlling a motorized screen.
Note that a small hook that screws onto the bottom of the device helps organize the cables. That’s a smart touch.

Finally, AirPlay and Chromecast compatibility makes it easy to stream content from a smartphone or tablet. The setup is accessible and well-organized, simplifying the integration of the W2720i into an existing setup, whether it’s cinema- or gaming-oriented.

The Remote Control

The remote control of the BenQ W2720i is compact, lightweight, and comfortable to hold. It features a logical layout of buttons, with direct access to source selection and image settings. Good news, the buttons are backlit, which facilitates its use in the dark, a real plus for movie sessions.

We appreciate the presence of a dedicated button for Google Assistant, allowing you to control the projector with your voice, as well as quick access to advanced settings without navigating through complex menus. The response is prompt, the range sufficient despite it being infrared and not Bluetooth. The whole feels quality and practical.

BenQ W2720iThe Screen

The BenQ W2720i projector is delivered without a screen, leaving the user the choice to opt for the projection surface most suited to their environment. It is entirely possible to install it without a screen by using a wall, but it is clear that the performance will be much better with a screen optimized for projection. Count on spending between 500 and 2,700 euros for screens of various sizes with specific treatments.

BenQ W2720iInstallation

The installation of the BenQ W2720i is facilitated by a manual 1.3x optical zoom and a vertical lens-shift of ±5%, allowing precise adjustment of the image position without degrading quality.

The automatic vertical keystone correction and manual horizontal keystone offer sufficient leeway to compensate for imperfect positioning. The projection distance varies from 1.0 to 1.3:1, which allows for a 120-inch image with a setback of approximately 2.65 meters. For an image with a 300 cm base, count on a setback of about 4.30 meters.

The alignment of the central optics simplifies the task, as do the markings on the chassis for ceiling mounting.

The focus is manual but precise, and the sharpness is uniform across almost the entire image. The installation menus are clear, with visual guides for each step. This flexibility makes the W2720i accessible to both novices and experienced users, while ensuring a well-framed and perfectly adjusted image for each session.

BenQ W2720iThe Image in Subjective Mode, a Detailed Image

The BenQ W2720i relies on a 0.47 inch DLP chip and a 4-LED light source, whose specific configuration (two blue diodes, one red, one green) allows it to cover 90% of the DCI-P3 color space, according to the brand. XPR technology simulates a 4K UHD resolution (3840 x 2160 pixels), providing a detailed, precise, and uniform image across the entire projection surface. Note its compatibility with 3D content. Glasses are offered as an option.

There are numerous available image modes: AI Cinema, Bright, Filmmaker Mode, Cinema, Useful (user) for SDR content. For HDR programs, the modes are more limited: HDR10, AI Cinema HDR, and Filmmaker Mode. Note the possibility to play with the power of the light source between Normal, Eco, Low Dynamic, and High Dynamic modes. The projector supports the 24p Cinema mode for movies.

The Cinema mode stands out for its color fidelity, with natural colors and accurate skin tones, while the Bright mode prioritizes brightness for partially lit rooms. In real use with Filmmaker mode activated, the image impresses with its softness, absence of video noise, and richness of nuances, both on HDR streaming films and on Blu-ray discs.

SDR content benefits from precise treatment, with well-maintained gamma and effective dynamic contrast. Dark scenes retain detail, even if the native contrast
