Buying a TV can be overwhelming when you begin to see just how many different options are going to be thrown your way. All shapes and sizes, thousands of different features, and then multiple brand names to choose from. You need to have a certain amount of TV knowledge in order to make the right choice. Like the difference between analog and HDTV.
You may run into questions like 'do you need, or do you want, an S-video input'? What about some RCA jacks, do you think you'll need those? And a digital comb filter, is that absolutely necessary? More questions than these can arise when you get into the different types and uses of the today TV. So learning a little about them goes a long way in your decision.
America seems to be sold on the idea that bigger things are better things. But is this a reality in shopping for a TV? There are some small TVs that you can't see through a squint, and some large ones that are so blurred you feel you need to sit a block away. So knowing what size fits the room you're going to put it in goes a long way with deciding your viewing quality.
TV sizes are obtained by measuring diagonally across the screen. Remember that a flat-panel TV is not going to take up as much space as a regular TV. You can even hang a flat-panel on the wall and not even consider your furniture layout except for looks.
With a screen that's over 40 inches, it's worth looking into a rear-projection CRT. This takes the concept of a projector and adds it to a screen for a one-two punch of a picture. The image gets projected onto the screen, which is then viewed from in front by you.
There are three cathode ray tubes that make up the colors of blue, red, and green that get thrown onto the projection screen. Home theaters have been the biggest advocates of this type of TV. Some of the advantages for you are getting the biggest screen for your money with great picture quality and good black level.
A few of the disadvantages of these giants are their heaviness and deepness, and the fact that they can't be watched under bright light. They're tough to maintain, and the have quite a slim angle of viewing. But they still deliver quality color viewing and have been used for years by countless thousands.
Now take your flat panel plasma TVs on the other hand. They're rolling out of the stores like wildfire. They're slim and have large screens, which makes them ever popular with consumers. You have your choice of either 'LCD' or 'Plasma.' The LCDs function much like a laptop computer. And the Plasma TVs operate by lighting up thousands of little small fluorescent lights.
Buying a TV takes some education, but this wall is easily climbed with just a little reading and research. Again, it's the basic differences in how they operate that separate them the most. All the added features then become matters of taste and personal preference. So go prepared when you begin your search, and get the best value for your dollar, and the best quality for your viewing.
