Projectors go wireless

New AV gear reduces presentation clutter - but adds new glitches.

As head of Boston Flight Sciences, an aerospace engineering firm, I often present at hotels and convention centers where everything depends on the projector I bring. In principle I like tech that simplifies my life, so I was pleased to review three new wireless LCD projectors.

Panasonic PT-LB60NTU
Panasonic PT-LB60NTU
$3,299

The Panasonic PT-LB60NTU has a level sensor that detects the projection angle and eliminates distortion over a wide range of elevations. The manual focus and zoom controls have the smooth, solid feel of precision optics. But the 5.7-pound chassis felt flimsy, and one front leg simply refused to lock. The wireless connection system seemed straightforward, but I had to reboot and try several times before it actually worked.
