The Big Picture

HDTVs are available in a variety of flavors, including front- and rear-projection, but flat-panel sets have emerged as the most popular option by far. What's not to like? You can get a big, beautiful picture from a display thin and light enough to hang on a wall. And the picture isn't the only attractive thing: Prices have dropped over 20 percent in the past year alone.

If you decide that a flat-panel HDTV is the way to go, you still have to determine which kind to buy: plasma or LCD. For screens smaller than 42 inches diagonal, your only choice is LCD. But for screens of 42 inches or larger, it's a matter of assessing which technology better suits your viewing conditions and preferences--and your budget.

Almost all sets on the market now, both plasma and LCD, are wide-screen models. Translation: Such sets have a 16:9 ratio of screen width to screen height (aspect ratio), which is the standard for HDTV and very close to the ratio used for most modern movies. As a result, the displays are more rectangular than the traditional, almost-square 4:3 sets of the past.
