1, if you consider the price, it will be better to buy a 4:3 TV, because 16:9 TV is more suitable for watching high-definition movies, DVDs and other programs, and the viewing effect will be better, the screen will be more realistic and clear, but the price will be more expensive, while 4:3 TV can only be used to watch ordinary TV programs, and the viewing effect is average, so the price is more expensive.

2. From the view of viewing effect, it is best to buy a 16:9 TV, because the screen of 16:9 TV can reduce the area with black border on the screen to a certain extent, thus increasing the display area of TV and increasing the viewing effect of TV. But the screen of 4:3 TV is generally more suitable for playing ordinary TV programs, and it is displayed around the screen.

When you buy TV, you need to consider not only the proportion of TV screen, but also the size of TV. Under normal circumstances, you should reasonably arrange the size of the TV according to the indoor area, viewing distance and wall size.

4. If the indoor area is relatively large, or the viewing distance is relatively long, or the wall area is relatively large, you should choose a TV with a relatively large size. If the indoor area is relatively small, or the viewing distance is relatively short, or the wall area is relatively small, you should choose to buy a TV with a smaller size.
