Verdict

The BenQ GV31 is a portable 1080p Full HD LED projector featuring a unique 135-degree rotating lens designed for easy ceiling projection. It offers 300 ANSI lumens of brightness, covers 98% of the Rec.709 color gamut, and includes a built-in 2.1-channel sound system with a dedicated 8W woofer and dual 4W tweeters. Key advantages include its internal battery providing up to 180 minutes of playback, integrated Android TV with native Netflix support, and versatile connectivity via USB-C (with Power Delivery), HDMI, and USB-A. However, it is limited by a relatively low brightness that requires dark environments for optimal viewing, lacks 4K and HDR support, and does not include a protective carrying case as standard.
