Digital Trends’ TV Buying Tips:

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.

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 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.

What resolution do I need?

All consumer HDTVs break down into either 720p or 1080p resolution, which represents the number of horizontal lines in the display. More is obviously better here, but at small screen sizes – like 32 inches – many people find it hard to distinguish the benefit of 1080p resolution. As our guide to screen size points out, viewing distance can also play a factor: The closer you sit, the more you’ll appreciate higher resolution. In general, many people start to see an obvious difference between 1080p and 720p as screens sized 40 inches and up.

Also take into account that much of the content available today doesn’t take advantage of full 1080p resolution. Many shows still broadcast in 720p or 1080i. Technically only Blu-ray discs and digital, non-video sources (like a PlayStation 3, Xbox 360, or PC hooked up to the TV), really offer true 1080p content. This makes 1080p a no-brainer if you want to play Mass Effect 2 with the most detail and watch Star Trek on Blu-ray, but less essential if you just play to watch standard over-the-air broadcast material.
