When buying a new TV these days there are a number of things that you would want to consider before doing so. Now a days, there are only 2 types of televisions to choose from and they are both flat screen TV's. Both of these TV's are high definition sets but where they differ is in their performance and their display capabilities.
There are two types of flat screen televisions and they are the Plasma and LCD type screens.
Plasma TV's work on plasma gas and LCD's work on a liquid crystal display. There are a few differences also between these two televisions. Some have 720 capabilities and others have 1080 capabilities meaning pixels per square inch which equates to the resolution of the screen and clarity of the picture that is being displayed on your TV.
Another difference between a plasma TV is that some of the older TV's have a considerable amount of glare to them for the fact that they have glass screens that reflect light, so if you are deciding to put a TV in a room, such a plasma, with a lot of light you might want to consider LCD first or think about moving it to the basement. Plasma TV's are much better for capturing faster moving images such as sports and action movies and are typically better for home entertainment theater systems.
The LCD TV is a better all around television. LCD televisions typically have a longer shelf life than a plasma TV and don't run the risk of burn it.
Plasma televisions sometimes, if you leave the TV on, one picture, for a long period of time can actually burn the picture into the TV.
One of the other great differences in TV's now a days is the frame refresh rates, that belong to certain TV's such as 60 Hz and 120 Hz. These capabilities are found in both plasma and LCD and provide a much more life like and more realistic image for viewers. It makes the movie less cinema like and more digital and animated. It is great for cartoons and fast sequence films.
When buying a TV it is always good to look at buying an extended warranty for the mere fact that newer televisions now a days can cost the price of the TV for repairs and if something were to happen, you usually only have a one year manufacturer warranty to cover the costs of repairs, but if something happens beyond that point, all costs are your own responsibility and could potentially leave you with a TV that has become nothing more than a paper weight if you cannot afford to fix it.
You can watch your favorite famous tv couples on tv with either one of your new tv purchases. if you get a new plasma tv, then your famous tv couples will look great. The same goes for if you get an lcd tv. You will probably experience even more joy watching famous tv couples and be able to laugh for a very long and very hard at your famous tv couples.
