Description

The BenQ MW855UST+ is a WXGA (1280x800) ultra-short-throw projector delivering 3500 ANSI lumens, designed to be mounted just centimetres from the screen so presenters can move freely in front of it without casting shadows or being dazzled by the beam. Its 0.35 throw ratio suits classrooms and meeting rooms with limited depth, and a 10,000:1 contrast ratio (FOFO) keeps text and graphics legible under normal room lighting.

The lamp light engine offers a choice of Normal, Eco, SmartEco and LampSave modes, extending bulb life up to 12,000 hours in the most economical setting. Connectivity is extensive for a room projector in this class: VGA input, two HDMI 2.0a inputs with HDCP2.2, composite video, LAN (RJ45), USB Type-A/Type-B/Mini-B and RS232, supporting both walk-up sources and network/control-system integration. A 10W stereo speaker pair, 2D keystone (+/-15 degrees) and +/-2% vertical lens shift round out the setup options.

The MW855UST+ is well suited to meeting rooms and classrooms that need a shadow-free, close-mounted projector, and is covered by BenQ's standard warranty.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
