## Long description

OPTOMA ZK420UST is a DLP ultra short throw 4K projector delivering 4200 ANSI lumens of brightness for installations that require large, high-resolution images from very close distances. Designed for classrooms, meeting rooms and digital signage, the projector supports native or pixel-shifted 4K content and produces clear text and detailed visuals even in environments with ambient light. Its ultra short throw lens and flexible installation options make it possible to place the unit near the projection surface to reduce shadowing and simplify cable routing.
