ViewSonic LS831WU-S 4500-Lumen WUXGA Ultra-Short Throw Laser DLP Projector - Certified Refurbished

Description

Enjoy large images in small rooms with the ViewSonic LS831WU 4500-Lumen WUXGA Ultra-Short Throw Laser DLP Projector. Its 4500 lumens of brightness can overcome ambient light in many situations, and its ultra-short 0.252:1 throw ratio make it a suitable option for small, well-lit small presentation areas. The WUXGA 1920 x 1200 native resolution is suitable for displaying many file and document types. The LS831WU has two HDMI inputs for connecting digital high-definition sources such as Blu-ray players and HD cable/satellite boxes. The projector also has a VGA input for analog sources, plus an RCA composite video and S-Video input. Its HDMI inputs are 3D-capable for viewing 3D Blu-ray discs with other compatible equipment, which is available separately. An HDBaseT port lets you run a single RJ45 cable to provide uncompressed audio and HD video over long distances. A VGA output allows daisy-chaining of multiple projectors or displays. The LS831WU includes a VGA cable and an IR remote control as an added convenience.

Long-Lasting Laser Phosphor Light Source

The laser phosphor light source lasts up to 20,000 hours for virtually maintenance-free usage and a lower total cost of ownership.

4500 Lumens of Brightness

The LS831WU combines 4500 lumens of brightness with a 3,000,000:1 dynamic contrast ratio to produce clear images in nearly any environment, including large, well-lit boardrooms, conference halls, and auditoriums

Large Images in Small Spaces

The ultra-short throw lens enables large images to be projected from very short distances to accommodate usage in small rooms. Additionally, blinding lights in front of the presenter, distracting shadows on the projected image, or glaring hotspots on the screen are virtually eliminated because the light source is close to the projection surface.

One-Wire HDBaseT Connection

With the integrated HDBaseT input, the LS831WU can receive uncompressed HD video and audio over a long distance via a single RJ45 cable.

Network Monitoring and Control

Your IT administrator can monitor, schedule, and manage the projector remotely, as well as receive projector status alerts with the integrated Crestron e-Control system and RoomView Express management software. Because the LS831WU is Crestron and AMX certified, IT administrators can control and monitor it for any size campus or enterprise.

360° Orientation

The construction of the LS831WU allows it to be installed in nearly any position, at nearly any angle. You can mount it pointing straight down at the floor of a museum exhibit or art gallery installation, or upside-down at a 45° angle.

SonicExpert Technology

This technology incorporates a large speaker and a more powerful amplifier to deliver a full 20 Hz to 20 kHz sound range to help captivate your audience with immersive sound.

Suitable for 24/7 Operation

The LS831WU is designed to withstand the rigors of 24/7 continuous use.
