Many of today's HDTVs go a step further, offering 1,080 lines of resolution. While 1080 is clearly the wave of the future-the standard is supported by Blu-ray, the high-definition DVD format-keep in mind that 720 is so sharp that viewers watching smaller HDTVs wilt be hard-pressed to notice the improvement 1080 brings. Sets capable of only 720 lines cost less: For a 32-inch LCD, the savings can be several hundred dollars. These units let you break into HDTV on a small budget.rnYou'll also want to make sure your HDTV has an HDMI connection. HDMI, short for High-Definition Multimedia Interface, uses a single cable that carries high-definition video along with up to eight channels of digital audio. It produces the best possible picture and sound when linking components such as a videogame console to your HDTV.rnBecause they are far thinner than traditional sets, HDTVs can be wall-mounted; ideally, you'll want the center of the screen positioned so it is at eye level when viewers are seated. But you'll need to be careful here, too. Never attempt to mount a television by yourself, and be sure to leave room for any cables you may need to connect components. You'll want to install a surge protector, as well, so your equipment isn't damaged by a sudden spike of electrical power. Consider using a wall-mountable model, positioning it out of sight behind the television.
