Bright 6000 ANSI Lumens projection

The ViewSonic LS921WU is a new WUXGA short-throw laser installation projector built for large, bright spaces. Its 6000 ANSI Lumens output and 1920 x 1200 native resolution suit home-theatre enthusiasts and commercial venues needing clear images up to 200 inches with the lights on.

Replaces lamp projectors with 20000-hour laser life

The 2nd generation Laser Phosphor light source removes lamp replacements and runs for 20000 hours, cutting maintenance cycles in gyms, restaurants or simulation centres. The upgrade makes sense when ambient light demands >3500 lumens and a 3000000:1 dynamic contrast ratio improves dark-scene detail over older lamp units.

Flexible install with short throw and lens shift

A 0.81-0.89 throw ratio and 1.1x optical zoom project large images from 1.04-3.83 metres, while wide horizontal and vertical lens shift plus 360° and portrait modes adapt to awkward ceilings. Dual HDMI 2.0b ports with HDCP 2.2 and built-in HDBaseT handle 4K HDR/HLG sources, and the 100-240 VAC supply fits global power without extra gear.
