Navigating the wilderness of high definition televisions can be a confusing mess with so many specifications and features to choose from. For a new consumer, there are several key factors to keep in mind while purchasing a new HDTV television set. There are different types of television available on the market, and with a number of choices, it’s easy to become confused as to the distinctions between genres. In the realm of flat-panel TVs, the primary categories are plasma and LCD sets. If you’re shopping for a set smaller than 42″, only LCD sets are available. For larger screens, the two different types of screes offer slightly different viewing experiences. If you’re on a limited budget, a plasma set will have slightly worse contrast of colors, and the darker shades will appear muddled compared to a similarly priced LCD screen. Alternatively, more expensive plasma screens will have noticeably better picture quality than LCD models.

The specifications of a television can be confusing, and a talented floor salesmen will be able to hurl them at a customer in an impressive and puzzling barrage of statistics. There are only a handful that you, as the customer, should be concerned about. The first, and arguably most important, is the screen resolution. Just as in computer monitors, the resolution measures the number of pixels present on the screen, with the first measure measuring the width of the screen and the second measuring the height. Currently, the digital content that appears on a TV screen comes in only a handful of formats, which can be broken down as follows:
480i: A typical analog TV display
480p: A progressive-scan DVD player
720p: Satellite and Cable broadcasts
1080i: Some higher quality satellite and cable broadcasts
1080p: Blu-Ray DVD player
It should be noted that these are the optimal settings for such a television. Just because you own a 720p television doesn’t mean you can’t enjoy Blu-ray DVDs, it just means you’re not tapping into the full potential of the player. To take full advantage of a high-definition input source, you’ll also need a high quality video interface. An HDMI or DVI interface will allow for the best-quality in picture, and most DVD players and video game consoles have the ability to connect into one of these ports.
The final important specifications are the aspect ratio and the contrast ration. The aspect ratio is the relationship between screen width and screen height. Old-school analog sets had a ratio of 4:3, but the industry has slowly been moving towards wide-screen formats like HDTV. Wide screen models have a ration of 16:9, which will make most movies and TV shows look great. Finally, the contrast ratio, which measures the difference between dark and light colors, should be examined. LCD specifications start around 600:1 while plasmas have an advantage at 1000:1. However, it should be noted that your primary concern should be how the screen fits your viewing environment, and the lighting conditions therein. Hopefully, with these guidelines, you’ll be able to narrow down the search and be well on your way to a brand new HDTV.
