HDMI Inputs
One of the most critical considerations with any TV is the number and type of inputs it has for hooking up devices to your TV. Most larger TVs now have at least three or four HDMI inputs plus two component-video inputs, which should be adequate for most current uses, while smaller sets typically have fewer of each type. Both types are capable of carrying high-definition signals from devices such as cable and satellite boxes and DVRs.

3D-capable models have HDMI 1.4 inputs, necessary to handle 3D signals. You can use the RF (antenna/cable) input to feed high-def TV signals, either from an off-air antenna or from a cable hookup. S-video and composite-video inputs are generally used with older gear such as a VCR or sometimes a DVD player. If you want to hook up a videogame system or camcorder occasionally, look for a TV with front- or side-panel inputs, which are more accessible than those on the rear of the set.
A handful of sets, typically high-priced models, can accept "wireless HDMI" signals. These TVs come with a separate media module, where all connections--such as from a cable box or Blu-ray player--are made. Audio and video signals are then sent wirelessly from the media console to the TV, leaving the power cord as the only remaining cable. There are several different technologies being used, including WHDI, WirelessHD (WiHD), Ultra Wide-Band (UWB), and even 802.11n, also known as Wi-Fi.
As new technologies take over, they present consumers with a number of evolving television choices. There are now many more choices than just the picture-tube sets of your childhood. Whether you want a small set for the kitchen counter or a large one for watching the big game, we can help you to compare TVs in a variety of sizes and price ranges.
