Overview
The ViewSonic LSC731WU is a powerful WUXGA installation projector designed specifically for auditoriums, large conference rooms and commercial displays. With a brightness of 7,300 ANSI lumens, it delivers clear, detailed images even in brightly lit environments. Low-maintenance laser technology and flexible installation features such as lens shift and 360° projection make it a reliable solution for demanding continuous-operation scenarios.
Benefits and special features
- 3rd-generation laser phosphor technology with up to 30,000 hours of life for low-maintenance operation.
- Great installation flexibility thanks to horizontal (+/- 29%) and vertical (+60%) lens shift plus 1.6x zoom.
- Integrated HDBaseT transmits uncompressed HD video and audio over a single network cable.
- Versatile projection options with 360° tilt and portrait mode for creative digital signage solutions.
- Precise image adjustment with 4-corner correction, warping and auto keystone for perfectly aligned projections.
- Edge blending support for seamless large-screen projection with multiple units.
- Future-proof control via LAN (Crestron, PJ Link, Extron, AMX) for easy system integration.
Picture and sound quality
Based on 3LCD technology with three 0.64-inch chips (MLA), the LSC731WU produces vivid colours with a dynamic contrast ratio of 3,000,000:1. As a 3LCD projector, the LSC731WU achieves identical white and colour brightness of 7,300 ANSI lumens – with single-chip DLP projectors, colour brightness can be well below the stated white brightness. The native WUXGA resolution ensures sharp reproduction of text and high-resolution video content.
For sound, a 16-watt speaker is built in, covering small to medium-sized rooms without an additional sound system.
- 2x HDMI 1.4 (HDCP 1.4)
- 1x HDBaseT for long-distance signal transmission
- 1x VGA in / 1x VGA out
- 1x audio in (RCA R/L) / 1x audio out (3.5 mm)
- 1x USB-A (5V / 2A) for powering dongles
- RJ45 (LAN control), RS232 and USB-B (service)
Mounting and installation
The projector supports flexible installation options, including ceiling mounting, 360° projection and operation in portrait mode. Set-up is made considerably easier by the wide lens shift range and the large 1.6x optical zoom. To protect against unauthorised access, the unit features password protection and a keypad lock.
