Deep-Dive Story & Problem/Solution

Replacing an Old Lamp Projector Without Rebuilding the Room

Many organisations want to retire lamp-based projectors but cannot move the mount, the screen, or the cabling. If the new unit’s lens does not cover the old throw distance, the upgrade turns into a construction project.

The LS850WU’s 1.36–2.18:1 zoom spans most standard-throw positions, and its lens shift, ±23% horizontal and ±50% vertical, re-centres the image without tilting. Installers can usually hang it on the existing bracket and align it optically.

The laser phosphor light source is rated for 20,000 hours and delivers 5,000 ANSI lumens with a 3,000,000:1 dynamic contrast ratio. Maintenance drops to almost nothing compared with the lamp unit it replaces.

Bright WUXGA Images for Large Audiences

The 16:10 WUXGA panel shows detailed spreadsheets and full HD video at sizes up to 300 inches. Horizontal and vertical keystone fine-tune geometry.

Extensive Connectivity and Control

Two HDMI inputs, HDBaseT, VGA in/out, composite, S-Video, two USB ports, RS-232, and LAN accommodate current and legacy sources as well as room control platforms.
