A 21:9 aspect ratio mode is optimised for Microsoft Teams Rooms, and installation flexibility comes from a 1.6x optical zoom, wide vertical (+60%/0%) and horizontal (±29%) lens shift, and ±25°/±30° H/V keystone correction, making the LSC731WU suitable for boardrooms, lecture halls, galleries and large simulation venues.
