DisplaySearch is a company that produces technology assessments, surveys, studies, and analyses of the current state of video display technology. Every year for the past four years they organize a two-day HDTV event. This year's, the DisplaySearch 5th Annual HDTV Conference, was held at the Hilton hotel at Universal City, CA.

Toshiba recently issued an update for its second-generation HD DVD players, primarily for the HD-A20 and the HD-XA2. I installed the update on an HD-A20, the middle model in Toshiba's HD DVD lineup (though shortly to be superceded in the launch of a third generation).

While I have decidedly mixed feelings about big-box consumer electronics retailers getting into the TV calibration game (see the following story on Best Buy, and an earlier story that also touches on Circuit City's calibration promotion) the commercial pull of these giants is already having at least one unanticipated benefit.

Last year when I reviewed the 1080p <A HREF="http://ultimateavmag.com/flatpaneldisplays/806sonykdl46/">Sony Bravia KDL-46XBR2</A>, I concluded that it "really knocked me out." Now we have the new Bravia KDL-46XBR4. It's similar in many respects to the 46XBR2, but offers significant improvements. These include better black levels, a new, slick on-screen menu system, and 120Hz operation&mdash;a feature that's showing up in more and more high-end LCD sets. Depending on its implementation, a 120Hz refresh rate can reduce image smear with moving images&mdash;one of the lingering problems of LCD display technology.
