Alright, maybe this is not a new issue for somebody but it is still a big issue for most people especially when they buy a new HDTV (High Definition Television). A decade ago people did not think about HD when they bought TV. They just came to the store and bought the TV set that they like it. They did not need to worry about resolution and refresh rate and so on and on. They mostly worry about the manufacture name.
However right now everything is different. When you buy a new TV, you just not only think about manufacture name, or how big the set is, but you need to think about the picture resolution, the refresh rate, the Vertical scan rate and anything else as the TV set offered.
You went to Electronics store to buy a new TV. Inside the store there are many different type of TVs, there are LCD, Plasma, and DLP TVs also some store still offer CRT TV.
So you need to pick one of the type of TV that you want to buy. Say you choose LCD Type of TV. There are 2 Types of LCD TV right now. Do you want LCD with Fluorescent light as a back light or with LED light as back light. Now it is getting more complicated when you choose a new TV, yes? OK let's continue.
Finally you decide to choose a regular LCD TV (Fluorescent light), then you have a choice of screen sizes from 13 inches to 55 inches. After size you need to choose the resolution 1080p or 720p. Then you go to refresh rate 8ms, 5ms, or 2ms. Then you go to the picture quality from 60Hz, 120Hz and 240Hz. Then you choose the contrast ratio from under 5000:1 to 150000:1. After all of this headache then come up with the price tag of the TV.
HDTV can be more complicated than just as these above, since you need to worry about the inputs and accessories that the set have. That's way every time you decide to buy a new HDTV make sure you talk first with friend that has a knowledge about HDTV or some expert on electronics. Never listen to sales person, because most of them just want to trap you on something that you don't really need it. Also you can choose the best TV for you.
These are the sample point to buy a new TV:
LCD TV (High End) - 52' screen size, 240Hz vertical scan, 1080p resolution, 150000:1 contrast ratio, 2ms respond time and under $3000 price tag.
