Digital Trends’ TV Buying Tips:

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.

What inputs should I look for?

A final consideration when buying a new HDTV is what you can connect to it. Make sure there are ample HDMI (High-Definition Multimedia Interface) ports to connect multiple components, such as a cable/satellite receiver, video game consoles, DVD/Blu-ray player, camcorder, and so on. At least three or four such ports is a must. A convenient bonus is when the TV also offers a USB port to connect a Flash thumb-drive or external hard drive full of music, photos and videos, or a SD or Memory Stick card slot that lets you insert a compatible card that contains photos and videos. If you think you’d like to connect your computer to the television for big-screen web surfing, look for one with PC connectivity. Many TVs today offer these additional features.

How large of a screen do I really need?

“Bigger is better” doesn’t make any more sense when choosing an HDTV for your living room than when choosing a couch for your living room. A lot of factors come into play. As a general rule, consider a TV 1.5 to 3.0 times the screen size. For instance, a 32-inch television might make sense for viewing distances as close as four feet away, and as far as eight feet away. Check out our guide to choosing the right size HDTV for more details, including a helpful chart.

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.
