Choosing Your Hd Tv Set

 

Back in the day, when there were only analog TVs around, picking out your own set was a much less intimidating affair than it is today. Technology has gotten more complicated; today’s HD TV sets are much slicker and sleeker than their tube TV counterparts. They come packed with featuressurround sound, pc compatibility, digital tuners, etc. For even the most technically adept, choosing the right TV is difficult. You have to wade through a quagmire of marketing hype, jargon and tech talk. You have to consider why you want a new TV, and of course, how high are you willing to go?

In the end, HD simply means a better picture. There are some important requirements to consider before you buy. Here’s a guide to the four different types of HD TV sets on the market today.

Direct View CRT: This is the TV we all know and love; it’s the type we grew up with. It’s the grand daddy of them all. Most of these are standard definition, although an increasing number are HD. However, without doubt, the tube TV is a dying breed. By federal law they are required to come equipped with digital tuners to receive DTV stations over the air, but the picture isn’t anything near what you would get with more modern HD TV sets. Direct-view TVs are also much bulkier and heavier than LCD’s and plasmas. Most stores don’t keep a large stock of tube TVs so you’re not likely to find much variety. The upside is that these are relatively cheap. So if you’re on tight budget, this would be your most economical choice. That being said, if you have more financial leeway, it’s better to invest in more modern technology.

Flat Panel LCD: These have revolutionized the TV industry. Flat screens can be hung on your wall like pieces of art, they can go above your mantelpiece or you can simply set them on a stand and enjoy the pristine sleekness of the form. Flat LCDs (liquid crystal display) are quite popular given their widespread availability and their competitive pricing. You can find 42 inch flat panel LCDs for around $700 these days. LCDs are also used as computer monitors. Their matte screens reflect less light than plasma screens, which means there is less danger of burn-in (which occurs when an image is etched permanently into the screen). LCDs are known for poor quality black levels as they use a backlight for illumination and there’s usually some light leak through the pixels.

Plasma Screens: These are known for their extremely top notch picture quality, with deep black levels and great color. Motion resolution is better than LCDs, however, you could argue that the difference is barely perceptible. Plasma screens are priced similarly to LCDs, however larger sized plasmas are generally less expensive than similarly sized LCDs. Plasmas are however, less energy efficient and they do tend to suffer from image burn-in.

Rear Projection TVs: Finally, we have the rear projection variety, which seem to offer the best price for larger screens. RPTVs use DLP technology or microchips. Within the set, light bounces off the chip via an internal lamp to produce color on the screen. These lamps must be replaced periodically; also, they take around 20 seconds to warm up and cool down which means the screen is completely dark for this phase. RPTVs are only manufactured by a handful of companies.
