Bright Full HD picture
The LSD400HD-ST delivers 4000 ANSI lumens at a native 1920 x 1080, so slides and video stay clear with the lights on. It uses a 0.65 inch DLP chip with a contrast ratio of 3,000,000:1 and 10-bit colour processing.
HDR and HLG are supported, and a Curved Surface Correction mode is included.
Big image from a short distance
With a throw ratio of 0.5 the projector fills a 40.2 to 300.15 inch screen from a throw distance of 45.72 cm to 332.23 cm, which keeps shadows and glare out of the presenter's way. The lens is fixed with manual focus, and there is no lens shift.
Horizontal and vertical keystone correction covers up to 15 degrees, with 4-corner adjustment for awkward positions.
Laser light, no lamp to change
The laser phosphor light source switches on and off instantly and needs no lamp replacement. Light source life is 20000 hours in normal mode and 30000 hours in eco mode.
