Conference Room Projector

Intensity Flicker. Like most DLP projectors, the WD720U generates color artifacts that some eyes can detect, but one surprising aspect of our test unit was a subtle but detectible intensity flicker only when the Brilliant Color option was engaged. Fewer color wheel segments might explain things, but the WD720U has a full complement of seven color segments. The good news is that this flicker was undetectable in video modes.
Fan NoiseDespite its large fan exhaust area, the WD720U is, after all, a 4,300-lumen projector, and its lamp generates a lot of heat. In Standard mode, the fan noise is relatively low frequency, but it would be distracting for anyone seated close by. This can be resolved by using Low lamp mode or by ceiling- or shelf-mounting.
The WD720U is a solid performer in the high-brightness projector category. Its data and video performance was very good although the faint flicker on data images with our test unit was a bit puzzling. The input/output combinations covered all the bases including a dual audio input that makes presenter voiceovers easy. Permanent installation was eased with an effective vertical lens shift, and control over image quality, computer synchronization, and network connection was extensive. In our opinion, the WD720U is a top value and earns our 5-star rating.
