Should you buy a TV with 50hertz 100hertz or 200hertz?

Answer 1

In Europe, television signals are broadcast at 50 fields per second, hence the native frequency of 50Hz. Televisions that offer 100Hz and 200Hz use a technique called interpolation to calculate what the picture would be like if there was one between the frames that are actually broadcast. (Note that in North America, the native frequency is 60Hz so the frequencies will be 60, 120 and 240Hz there.)

The aim of the interpolation (or frame doubling) is to create smoother movement than with a 50 or 60Hz display. In practice, the improvement is not huge and in some cases, temporal interpolation can cause unwanted effects that weren't in the original signal. Some manufacturers do it better than others and all of them handle certain types of program better than others. To offer a suggestion about the right model to buy would ignore the range of performances that can be seen for different televisions and different content.

The best advice is to make a short list of models based on the overall specification of size, inputs, in-built tuners and so on. Then get to a store and watch each of them with the program type that you will be watching. (don't be satisfied with manufacturers' demonstration programs). The best model to buy is the one that looks best. After all, you are buying it to watch, so make it one that you enjoy watching.
