Description

The LS711HD is a compact, lamp-free short-throw projector from ViewSonic's Luminous Superior series, using 3rd generation laser phosphor technology to deliver 4,200 ANSI lumens at native 1080p Full HD with a 3,000,000:1 contrast ratio. A 0.49 short-throw ratio produces a 100" image from just 1.1 metres without obstruction from shadows, scaling from 35" up to 300" for a wide range of commercial spaces including restaurants, galleries and exhibition stands. H/V keystone correction with 4-corner adjustment, 360-degree projection and portrait mode add further installation flexibility, and a dedicated golf mode suits simulator screens. An IP6X dust-resistant sealed optical engine keeps the unit maintenance-free, while a light source rated for up to 30,000 hours and compatibility with Crestron, AMX, PJ Link and Extron control systems make the LS711HD well suited to always-on commercial installations.
