Digital Trends’ TV Buying Tips:
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.
Do I need an ATSC tuner?
If you plan on watching, free, over-the-air programming, then yes. As of 2009, all over-the-air broadcasts use the ATSC standard. Pretty much all HDTVs manufactured over the past few years will include this feature.
LCD or Plasma?
Debating between LCD or plasma can almost get as subjective as debating between chocolate and vanilla. But unlike the never-ending ice cream debate, there actually is a superior TV choice, depending on how you plan to use it.
Check out some of our previous guides on the subject to get a better look, but in short, plasmas use more electricity, come in bigger sizes, have deeper blacks, don’t suffer from motion blur, and offer an unlimited viewing angle that’s best for off-axis viewing. LCDs are more energy-efficient, have fewer problems with glare due to their matte screens, can hold an image for hours or days without suffering “burn-in,” and generally look brighter.
