Description

The BenQ MH856UST+ is a 1080p (1920x1080) interactive ultra-short-throw projector delivering 3500 ANSI lumens, built for classroom interaction and collaboration. Its 0.33 throw ratio allows mounting just inches from the board, letting teachers and students work in front of the screen without shadowing or beam glare, and a 10,000:1 contrast ratio (FOFO) keeps Full HD content sharp under classroom lighting.

A choice of Normal, Eco, SmartEco and LampSave lamp modes extends bulb life up to 12,000 hours. Connectivity includes dual HDMI 2.0a inputs with HDCP2.2, VGA input plus monitor output, composite video, LAN (RJ45), USB Type-A/Type-B/Mini-B and RS232, giving flexibility for both local sources and networked classroom AV setups. Twin 10W speakers provide adequate room-filling audio without an external sound system, and 2D keystone correction (+/-15 degrees) simplifies alignment in a fixed short-throw mount.

BenQ backs the MH856UST+ with 5-year coverage, reflecting its positioning as a durable, education-focused interactive projector for everyday classroom use.
