Description

The BenQ X3100i is a 4K UHD 4LED projector delivering 3300 ANSI lumens with 100% DCI-P3 and 95% Rec.709 colour coverage, positioned as BenQ's flagship console/gaming-capable model that also performs strongly as a high-spec data and presentation projector. Its 4LED light engine is rated for 20,000-30,000 hours across normal and eco modes, removing the recurring cost and downtime of lamp replacement.

A 1.15-1.5 throw ratio with 1.3x zoom and 40-60% vertical lens shift give considerable placement flexibility, letting the X3100i be table-mounted or ceiling-mounted and still fill a 100-inch image from around 2.5 metres. Dual HDMI 2.0b inputs with HDCP 2.2, RS232 control and a 12V trigger support integration into AV racks and control systems, while 600,000:1 dynamic contrast and input lag as low as 4.2ms (1080p/240Hz) keep fast-moving content sharp and responsive.

Twin 5W chamber speakers with eARC and Dolby Atmos pass-through round out the package, and the projector carries BenQ's standard 3-year warranty.
