LCD TV Reviews

When I reviewed Sony's <A href="http://ultimateavmag.com/flatpaneldisplays/408sonykdl52/">KDL-52XBR4</A> LCD TV in April 2008, I was very impressed for the most part. With excellent color and exceptional detail on HD material, my only reservations were a slightly soft appearance on SD content and a black level that remained a bit elevated on real-world programs. (The black level mysteriously dropped on certain test patterns, even with all dynamic settings disabled.) Also, its list price of $4000 was pretty steep.

The Right Stuff

I’m old enough to remember when Sony introduced its first XBR models, which were top-of-the-line CRT TVs. Since then, the company has continued to use XBR in the model designation of its flagship flat panels, adding a number to indicate each new generation.

The new KDL-55W900A is Sony’s newest, top-of-the-line, non-XBR set. All of the XBRs, going forward, will be Ultra HD (4K) sets, but the KDL-55W900A, as all of the KDL designs, is firmly in the standard HD, 1920 x 1080 camp. It’s an edge-lit design with local dimming, but its marquee feature has nothing to do with contrast and black levels. Color is the plot here, and Triluminos, a term Sony has used in the past (see sidebar), promises a wider color gamut.

All LCD HDTVs require some form of backlighting. The LCD panel’s pixels modulate the light and provide filtered color, but without backlighting to shine through the panel, you’d have no picture. Recently, LEDs (light-emitting diodes) have replaced the fluorescent backlights used in older flat-screen LCD sets. LCDs aren’t perfect in blocking light (which is why so many early models had poor black levels), but if you can shut off or dim the LEDs on demand, the LCDs’ light-blocking chores become far more efficient. And LEDs can do this; they can be shut off and turned back on almost instantaneously in reaction to the signal coming in.

A number of years ago, I wrote an article about putting together a backyard home theater using an inflatable front-projection screen from Sima. It was a blast—and more than just a blast of air from the pump that inflated the Michelin-Man-dream-date, 72-inch-screen-covered blimp in less than 6 minutes. I took the setup to a friend’s house one Saturday during my “research” where we had a three-family movie night on the patio in his backyard. Sodas and margaritas flowed freely that evening. Much popcorn was popped. I don’t think any of us remember the actual movie, but to this day none of us has forgotten how much fun we had—more fun, as a matter of fact, than we’d ever had watching a movie the proper way inside the house.
