Pros

Both vertical and horizontal lens shift allow flexible projector placement without rearranging the room
Supports HDR10, HDR10+, and HLG for a broad range of high dynamic range content
Three HDMI ports and three USB ports provide ample wired connectivity for multiple devices simultaneously
Wireless options cover AirPlay, Chromecast, Miracast, and Bluetooth, making device streaming straightforward
Lamp rated at 30,000 hours in eco mode, reducing the frequency of lamp replacements over time
Built-in smart TV, voice commands, and a dedicated smartphone app offer multiple ways to control and navigate content

Cons

No motorized focus or zoom, requiring manual adjustment each time the setup changes
Dolby Vision and Dolby Atmos are not supported, limiting compatibility with certain premium content formats
No RJ45 port means a wired network connection is not possible
The built-in speaker lacks stereo output and the listed audio output power is 0W, making an external audio solution necessary for practical use
No external memory slot limits local media playback options
Not DLNA-certified, which may affect integration with certain home network media setups

Who is this for?

This projector is well matched for dedicated home cinema rooms where a large, high-quality image is the priority. Its 4K resolution combined with HDR10, HDR10+, and HLG support makes it a solid fit for users who regularly watch HDR-graded content and want accurate color depth from a 10-bit panel. The dual-axis lens shift and 300″ maximum projection size suit those setting up in larger rooms with fixed or semi-permanent installations. Built-in smart TV functionality, AirPlay, Chromecast, and voice command support also make it practical for users who want an all-in-one streaming setup without relying on external media players.

Who is this NOT for?

Users who need a truly portable or flexible setup will find the 6,100 g weight and the absence of motorized focus and zoom inconvenient, as repositioning requires manual readjustment each time. Those who rely on a wired home network will be limited by the lack of an RJ45 port, and users invested in a Dolby Vision or Dolby Atmos ecosystem will find neither supported here. The built-in audio solution is also insufficient for anyone expecting usable onboard sound, making this a poor fit for those who want a self-contained setup without a separate audio system.

Final Verdict

The BenQ W4100i is a capable home cinema projector built around a clear set of priorities: a large, detailed image with broad HDR compatibility and a well-connected smart platform. Its 4K resolution with HDR10, HDR10+, and HLG support, paired with dual-axis lens shift and a 30,000-hour eco-mode lamp life, makes it a practical long-term choice for users setting up a dedicated viewing space. That said, the absence of motorized optics, no wired network port, and an underpowered built-in audio setup mean it works best as part of a more complete home theatre system rather than a standalone unit. For users whose setup can accommodate those requirements, the W4100i delivers a coherent and feature-rich projection experience.
