Digital Trend’s TV Buying Tips:

What are widgets?

Many of the top television manufacturers – including Sony, Sharp, Panasonic and Samsung – include Ethernet jacks on the back of their premium televisions for high-speed Internet connectivity (or in some cases, have integrated Wi-Fi for wireless connections). TV viewers will then use the remote to select “widgets,” graphicalicons on the screen that plays relevant (and customized) content ranging from YouTube videos and Flickr photo galleries to local weather, news, sports updates and stock quotes, usually delivered by Really Simple Syndication (RSS). Even more exciting is the partnership between Netflix and various TV companies, such as LG and Sony, allowingtelevision viewers to access tens of thousands of movies on-demand, many of which are in high-definition.

Do I need a 120Hz set? What about 240Hz?

This popular LCD TV-based technology helps reduce motion blur. Pronounced “120 hertz,” 120Hz technology essentially doubles the speed at which frames are displayed, from 60 frames per second to 120 frames per second, resulting in a clearer moving image, especially in fast-action video sequences.

Since the screen can display more frames than a movie actually has, many TVs will artificially generate in-between frames where they don’t exist to make motion look smoother. Some people find the look more fluid, while some people think it looks artificial and odd. Fortunately, all TVs that offer it also offer an option to turn it off, if you don’t like it. We recommend testing it in person to see the effects for yourself before deciding whether or not you should pay extra.

Which other panel specs should I pay attention to?

In short: brightness, contrast, and refresh time.

Brightness is measured in Candelas per square meter, or cd/m2. A typical figure, for instance, might be 500 cd/m2. More is always better, especially if you plan to plant your TV in a bright room where the screen will have to overcome other light sources.

Contrast is measured as a ratio of the brightest white a TV can produce, over the darkest dark. For instance, Insignia’s NS-L42X-10A offers a 4,000:1 contrast ratio. More is also better, but beware of “dynamic contrast ratios,” which use unrealistic measurement conditions (the brightest white is measured with the backlight set to full, and the darkest dark with the backlight to minimum, even though those levels could never occur side by side on the same screen) to inflate the number to levels like 2,000,000:1.

Refresh time is measured in milliseconds, such as 5ms. Lower is always better, and will prevent the “ghosting” that can sometimes be seen in fast-motion video.

What is a LED backlighting?

Traditionally, LCD TVs have used compact fluorescent (CFL) tubes placed behind an LCD panel to provide the backlighting that literally lights up the screen. More modern LED TVs replace these tubes with clusters of light emitting diodes – LEDs.

When LEDs are placed at the edges of the screen, as CFL tubes traditionally were, TVs can be made significantly thinner, and LEDs use less power than fluorescents. The most inexpensive LED-lit HDTVs take this approach.

However, the biggest advantage to using LEDs is realized when they light the screen in a grid from behind. Sophisticated electronics vary the intensity of every LED in accordance with action on the screen, making dark areas of the image darker, and bright areas brighter. This effectively increases the contrast ratio compared to uniform lighting. Although it also increases costs, many people believe this type of LCD is the first to truly rival plasma on black levels.
