Christie LWU501i: High Resolution
October 30, 2012
Marginally useful audio quality. The Christie LWU501i's built in 16-watt stereo speakers are loud enough to fill a large conference room or classroom, but the quality is only fair. Most dialog in my tests was understandable, but in one challenging clip it was hard to make out the words because of a bottom of the barrel echo effect. If you need good audio quality, plan on using an external sound system.
No 3D. Given the wide availability of 3D in DLP projectors, it's worth mention that the LWU501i lacks 3D. However, that's standard for LCD-based data projectors.
The Christie LWU501i's long list of strengths and lack of real weaknesses make it an undeniably impressive beast. It delivers 1920x1200 resolution, high quality data images, better video quality than most data projectors, brightness suitable for a large conference room or small auditorium, and lots of convenience features, including motorized zoom, focus, and lens shift.
Even better, beyond these core features are extras that include a flexible picture by picture mode, a DICOM SIM preset for medical images, a choice of lenses, and more. The hefty price tag may make you think twice. But there's easily enough here to both justify the price and put the LWU501i on your must see list.
