More HDMI inputs, fewer analog jacks on new TVs

When you're setting up your new HDTV, you're likely to find fewer analog video connections but more HDMI inputs.

Some of the LCD and plasma TVs we've tested recently (Ratings are available to subscribers) from Insignia, LG, and Samsung don't have S-video inputs and others lack both S-video and composite-video connections. The high-priced Sony Bravia KLV-40ZX1M has nothing but a single HDMI input, evidently intended to be used with a receiver that handles all the other connections.

While analog connections are dwindling, HDMI inputs are proliferating. We're just starting to test a new Sharp set, the Aquos LC-52E77UN, which has five HDMI connections, the most we've seen. Many of the bigger, higher-priced models we've tested from major brands have three or four HDMI inputs, and even smaller, lower-priced TVs generally have two of these digital connections.

In many cases, at least one of the HDMI connectors is on the side of the set, rather than the back, which makes it easier to get at, especially if the TV will be wall-mounted or squeezed into a tight space in an entertainment center. We haven't yet tested any sets with front-mounted HDMI connections—for connecting a camcorder or game system—but that may not be far off. There are some TVs with HDMI inputs on the front of the set. We don't have any such sets in the current Ratings, but we have seen front-mounted HDMI inputs on previously tested models such as the Panasonic TH-50PZ750U. —Ed.

There's no downside for most users, as far as we can see. One of the biggest advantages is that HDMI can carry high-definition signals; of the analog video inputs, only component-video can do so. And many upconverting DVD players require an HDMI connection if you want to use this feature. Another plus: Even when you're not watching high-def, HDMI might give you better picture and sound quality than the older inputs can provide.

And notice that all the analog connections have the word "video" in their name. That's because they carry only the video signal, requiring a separate connection (either left/right audio cables or multichannel digital outputs) for sound. HDMI connections, by contrast, carry both video and audio on a single cable, which can cut down significantly on the dreaded cable clutter.

Component-video connections seem to be hanging in there, most likely because they are HD-capable, with most new sets having one or two such connections. Manufacturers are likely to keep these in place for years to come, since older DVD players and cable boxes might not have an HDMI connection. —Eileen McCooey
