BenQ W2720i Review: 4K Cinema Color on a 120-Inch Screen

The BenQ W2720i is a cinema-focused 4LED projector that displays a 3840 x 2160 image through XPR pixel shifting. Its strongest features are natural-looking color, factory-calibrated cinema modes, HDR10+ support, flexible automatic setup tools and an included Android TV dongle. Tech Steve was particularly impressed by its movie performance, sports color, image uniformity, upscaling and dark-scene presentation on a 120-inch screen. Gaming is responsive at 4K 60 Hz, but 120 Hz and 240 Hz operation require a reduction to 1080p.

Video summary

Tech Steve demonstrates the W2720i with movies, sports, dark scenes, gray-screen uniformity tests and lower-resolution material. He found its colors natural and television-like on a 120-inch screen, while dark scenes avoided the washed-out gray appearance associated with weaker projector contrast. He also observed consistent gray-screen uniformity, effective upscaling from 720p and 1080p, unobtrusive fan noise and usable built-in audio. The walkthrough covers AI Cinema Mode, the automatic picture-tuning camera, manual focus, screen adjustment, keystone correction, the included Android TV dongle, streaming applications, HDMI connectivity, eARC and gaming latency. Although the projector can accept a 4K 120 Hz signal through HDMI 3, that signal is displayed at 1080p 120 Hz rather than 4K 120 Hz.

Bottom line

Tech Steve Takeaway

The W2720i is a strong choice for shoppers who want a permanently installed, color-focused projector for movies, sports and streaming on a large screen. Its accurate-looking color, effective upscaling and convenient automatic setup features stand out, but serious gamers should remember that native-resolution playback tops out at 4K 60 Hz.

Designed for permanent big-screen movie and streaming installations, the W2720i uses a single-chip DLP system with XPR pixel shifting to display 3840 x 2160. It supports HDR10+, HDR10 and HLG, includes AI-assisted picture adjustment and provides a 1.0-1.3 throw ratio with optical zoom, limited vertical lens shift and automatic screen fitting. Three external HDMI connections, eARC and the included QS02 streaming dongle provide broad source and audio flexibility.

Picture quality

The W2720i displays an 8.3-million-pixel 3840 x 2160 image using a single-chip DLP system with XPR pixel shifting. Tech Steve found its movie presentation colorful, sharp and convincingly cinematic, with natural-looking grass and uniforms during sports. He also reported consistent gray-screen uniformity without obvious dirty-screen artifacts. Pixel Enhancer 4K is available to improve lower-resolution texture and detail, and Steve considered 720p a practical minimum for a consistently clean image while describing 1080p upscaling as close to 4K in appearance.

HDR performance

HDR support includes HDR10+, HDR10 and HLG, with HDR-PRO processing and dedicated HDR picture modes. The projector also provides global and local contrast processing; the latter adjusts image regions through processing rather than physical local-dimming zones. Tech Steve observed colorful highlights and a dark, non-gray presentation in his movie demonstrations. Dolby Vision is not listed as supported.

Gaming performance

The maximum verified rate at the 3840 x 2160 output resolution is 60 Hz, with a manufacturer input-lag claim of 17.9 ms at 4K 60 Hz. Reduced-resolution modes support 1080p at 120 Hz and 240 Hz, with claimed input lag of 12.8 ms and 6.5 ms respectively. HDMI 3 can accept a 4K 120 Hz source, but the projector downscales and displays it at 1080p 120 Hz. ALLM is supported, while Motion Enhancer 4K frame interpolation does not increase the 4K input limit beyond 60 Hz.

Motion handling

Motion Enhancer 4K uses frame interpolation to smooth movement, and 24p True Cinema is available for film playback. Higher-refresh gaming is possible at 1080p, including 120 Hz and 240 Hz modes, but 4K presentation remains limited to 60 Hz.

Sound quality

The built-in system consists of two 5-watt speakers for 10 watts total. Tech Steve considered it adequate for dialogue, casual television and basic movie playback. A soundbar or AV receiver remains the better choice for cinematic impact, with HDMI eARC, optical S/PDIF and 3.5 mm audio outputs available. Dolby Atmos can be passed through over eARC.

Features and connectivity

The US configuration includes the BenQ QS02 dongle running Android TV 11. It provides Netflix, Prime Video, Disney+, YouTube, downloadable Play Store applications, Chromecast, AirPlay and Google Assistant. The included remote controls both the streaming interface and projector functions, reducing the need to switch between remotes. The dongle supports streaming at up to 4K 60 Hz.

Calibration notes

BenQ specifies 90% DCI-P3 and 98% Rec.709 coverage through its CinematicColor system. The projector includes a factory calibration report, while BenQ separately advertises 100% Rec.709 color accuracy with Delta E below 3. Cinema, FILMMAKER MODE, ISF Day, ISF Night and User modes provide several calibration starting points. AI Cinema Mode uses ambient-light, camera and distance-sensing hardware with content analysis to adjust brightness, contrast and saturation when room or installation conditions change.

Models and configurations

The W2720i is sold as one projector model rather than in size-specific hardware variants. BenQ supplies projection calculations covering approximately 30- to 200-inch diagonal images. Its 1.0-1.3 throw ratio can produce a 120-inch image from approximately 2.7 meters at the wide end. Tech Steve used a 120-inch screen for his demonstrations and considered that size a strong match for high-quality 4K sources. Apparent brightness will decrease as the projected image grows and will also depend on screen gain and ambient light.

What to consider

The 3840 x 2160 image uses XPR pixel shifting over a 1920 x 1080 non-XPR DMD resolution rather than a native 4K imaging chip
Native-resolution playback is limited to 4K 60 Hz; accepted 4K 120 Hz signals are displayed at 1080p 120 Hz
The fastest 240 Hz mode is limited to 1920 x 1080
Vertical lens shift is limited to plus or minus 5%, providing less placement freedom than larger installation projectors
Dolby Vision is not listed among the supported HDR formats
The 10-watt stereo speakers are suitable for basic playback but lack the scale of a dedicated soundbar or theater system
A ceiling mount and compatible DLP-Link 3D glasses must be purchased separately
Its 16.45-inch-wide chassis is better suited to a shelf or permanent mount than frequent portable use

Tech Steve verdict

The BenQ W2720i is best suited to movie and streaming enthusiasts who want a large, natural-looking image without maintaining a traditional projector lamp. Its 4LED light engine, calibrated cinema modes, HDR10+ support, short 1.0-1.3 throw ratio, automatic screen tools and included Android TV dongle make it a well-rounded permanent-theater option. Its main tradeoffs are XPR rather than native-chip 4K, a 60 Hz limit at 3840 x 2160, limited vertical lens shift, no listed Dolby Vision support and modest built-in speakers. Buy it for cinema, sports and convenient big-screen streaming; choose a gaming-focused display if maintaining 4K resolution at 120 Hz is essential.

What makes it different

Exclusive technology

AI Cinema Mode

Uses the projector's ambient-light, camera and distance-sensing hardware together with content analysis to adjust picture parameters such as brightness, contrast and saturation. It can be recalibrated after room or installation conditions change.

CinematicColor

BenQ's cinema-oriented color system. The W2720i is specified for 90% DCI-P3 and 98% Rec.709 coverage, with factory color calibration supplied with the projector.

HDR-PRO

BenQ's projector-specific HDR processing suite for balancing highlight, shadow and overall contrast detail.

Global Contrast Enhancer

Analyzes the complete image and adjusts its overall contrast.

Local Contrast Enhancer

Divides the image into processing regions and adjusts dark and bright portions independently. This is image processing rather than hardware local-dimming zones.

Pixel Enhancer 4K

A detail and super-resolution process intended to improve the apparent texture, contrast and sharpness of lower-resolution material.

Motion Enhancer 4K

Motion-estimation and motion-compensation processing that interpolates frames for smoother movement. It does not increase the projector's verified 4K input limit beyond 60 Hz.
