Walk into your local electronics emporium and look at the wall of screens. It's a beautiful sight. All of the displays look so wonderful, but where do you start? What do you need to know to find your perfect high-def match? Purchasing your first HDTV can be a daunting task if you aren't armed with the proper information when you enter the carnivorous den of your local electronics superstore. There are a couple of areas I'd like to focus on in this guide. The first thing to consider is the type of TV, and which is best suited to your viewing environment. This consists of the physical space the TV will occupy and any devices you plan to use with it will weigh heavily on your decision. Also important are the features and specifications that a new TV can offer. Buzzwords like 1080p, contrast ratio, HDMI, and 120Hz will be thrown at you as soon as you strike up a dialogue with a salesperson (or as they stalk you up and down the aisles). With a little preparation, you can be an informed consumer with the power to overcome jargon-filled sales pitches and, in the end, make the right decision for you.
