BenQ LH830ST 4000 Lumen Full HD Short Throw Laser Business Projector
The BenQ LH830ST is a 4000 ANSI lumen Full HD 1080p laser projector built for boardrooms, classrooms, training rooms and golf simulator setups where space is tight. With a 0.496 short throw ratio, a 3,000,000:1 contrast ratio, a 20,000 hour laser light source and 16.7 ms input lag, it produces large, bright, sharp images from just a short distance away.
Bright, Sharp Full HD Images
BenQ's DLP engine delivers 4000 ANSI lumens of brightness with native Full HD 1080p (1920 × 1080) resolution and 30-bit colour depth for 1.07 billion colours. With 93% Rec. 709 coverage and HDR10 and HLG support, content looks accurate and vibrant even with ambient light in the room.

Short Throw for Tight Spaces

Versatile Picture Modes
Twelve picture modes including Entertainment, 3D, Bright, Cinema, Golf, HDR10, HLG, Presentation, sRGB, User 1, User 2 and Vivid let you tune output to the room and content. The dedicated Golf mode is particularly useful for simulator installations.
Responsive 16.7 ms Input Lag
With 16.7 ms input lag at 1080p 60Hz, the LH830ST is responsive enough for simulator and casual gaming use alongside its primary business and education roles.
Quiet Operation
