Christie LWU505 Widescreen 1920x1200
Conference Room Projector

Disappointing audio quality. The Christie LWU505's built in 10-watt mono speaker is loud enough to fill a large conference room or classroom, but the quality is such that it's best described as a convenience feature. The audio is both tinny and suffers from a bottom of a barrel echo effect, a combination that makes it hard to understand. If you care about audio quality, you'll need an external sound system.
Picture-in-Picture limitations. The Picture-in-Picture and Picture-by-Picture modes offer less flexibility than you would expect. For example, although you can show one image from a PC connected through the VGA, HDMI, or DVI-D port along with one video image connected through any other port, you can't show images from two sources connected to, say, the VGA and the HDMI ports. More generally, no matter what you have plugged into the VGA, HDMI, and DVI-D ports, you can show an image coming through only one of those ports at a time. The feature would obviously be far more useful if you could show images from any combination of input ports.
Obscure menu commands. Although most of the menu structure is self-explanatory, there are a few commands that aren't. The combined Picture-in-Picture and Picture-by-Picture mode in particular took some trial and error experimentation plus reading the instructions before I could understand how to use it.
As may be obvious, the Christie LWU505 does the important things well and runs into problems only on minor issues. The combination of high resolution, suitable brightness for anything up to a large conference room or small auditorium, high quality images for data, and acceptable quality images for video is enough to make it worth considering. The flexibility in placement thanks to the zoom lens and choice of zoom lenses, plus such conveniences as lens shift and four-corner keystone correction add a polish that makes it even easier to recommend. If you need 1920x1200 resolution and a projector that's bright enough for anything from a large conference room to a small auditorium, the Christie LWU505 is a solidly built projector worthy of your consideration.
