Product Overview
Featuring stunning WUXGA resolution and 4,500 lumens of brightness, the ViewSonic ® LS831WU Laser Projector is the ideal solution for modern business and education environments. Designed with a laser phosphor light source lasting up to 20,000 hours, this projector delivers long-term, virtually maintenance-free usage for any boardroom or classroom. With its 0.25 ultra-short throw ratio, HV keystoning and 4 corner adjustments, the LS831WU makes installation a hassle-free experience. What's more, the ultra-short throw ratio allows you to place the projector just inches away from a wall or screen to give you a huge image for less cost than a comparably sized display.

Extended warranties are usually very inexpensive and can save you thousands in the future.
It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.
Electronics
can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new
electronics
should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
