Description

The LS921WU is the short-throw counterpart to ViewSonic's LS920WU, using 2nd generation laser phosphor technology to deliver 6,000 ANSI lumens and a 3,000,000:1 contrast ratio at native WUXGA (1920x1200) resolution for up to 20,000 hours of consistent brightness.

Its 0.81-0.89 throw ratio suits confined installation spaces up to a 200" screen, and wide lens shift (horizontal ±23%, vertical ±50%) combined with a 1.1x optical zoom, H/V keystone and 360-degree projection gives installers flexibility for blended projection in restaurants, gyms and simulation or experience centres, including portrait-mode mounting.

Dual HDMI 2.0b (HDCP 2.2) ports support original 4K content with HDR/HLG, and a compact chassis with built-in HDBaseT receiver keeps cable runs simple, ensuring the LS921WU fits neatly into space-constrained, centrally-managed AV installations.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
