5500 ANSI Lumens 4K HDR Laser Projector

The ViewSonic LS901-4K is a 5500 ANSI lumens laser projector delivering native 3840x21060 resolution with HDR and HLG support. It is built for business installations that require bright, detailed images on screens up to 300 inches in environments where ambient light cannot be fully controlled.

Installation flexibility and upgrade value

The projector replaces lamp-based units with a laser light source rated for 30000 hours of operation, removing routine lamp replacements and reducing maintenance downtime. Its 1.7x optical zoom, 360-degree projection, vertical lens shift and 4-corner adjustment allow placement in difficult rooms where fixed-throw or ceiling-only models cannot be installed.

Sustained operation behaviour

The laser engine maintains consistent brightness and colour accuracy over extended sessions without the brightness decay typical of ageing lamps. Dynamic contrast of 3000000:1 and 1.07 billion display colours remain stable during long presentations or digital signage loops, while LAN control via Crestron, AMX, Extron, PJ Link, ATEN and vController enables remote monitoring and scheduled power cycles for unattended operation.
