Large Venue WXGA Projector
March 4, 2009
Convergence. Three-chip DLP projectors eliminate color separation artifacts, and in general have better color performance than single-chip machines do. However, this comes with a price; single-chip DLP projectors don't have to worry about convergence, while three-chip models do. Our test unit was slightly out of convergence, but not so much as to impact image quality. Any projector with three imaging devices, whether they be DLP, LCOS, or LCD, may be expected to go out of convergence over the projector's life. And if you happen to have a projector with a convergence problem, you can always take advantage of Sharp's warranty and send it in for service.
Brightness uniformity. While using both lamps, the P560W had nearly perfect brightness uniformity, in the 90-95% range. However, when using one lamp at a time, one edge of the screen becomes somewhat dimmer than the other. When using Lamp 1, the right edge of the screen was 23% dimmer than the left edge, and vice versa when using Lamp 2. This phenomenon means that for photography or other content where constant, even illumination is needed, the best choice is to use both lamps simultaneously.
Weight and size. Without the lens, the XG-P560W weighs 55lbs. With the lens in place, it weighs four pounds more. While large fixed-installation projectors are nothing new, there are smaller and lighter options if all you're looking for is a 5,000 lumen projector.
The XG-P560W is a bright WXGA presentation projector that's perfect for lecture halls and other large venues. The three-chip DLP design is audience friendly and delivers great color with minimum pixelation. The projector is easy to use, has a variety of lenses, and its lamp options make it versatile enough to be installed with minimal lamp maintenance. At street prices below $12,000, the XG-P560W is one of the least expensive three-chip DLP projectors on the market. If you're looking for a fully-featured light cannon with great warranty back-up, look no further.
