This proportion is still the dominant standard of television today.

Because of this tradition, we now receive the TV programs are such a proportion, so the proportion of LCD TV screen is also to 4: 3 mainly. However, the real film is generally wide-screen, the widescreen movie converted to 4: 3 will always result in picture quality, shape or loss of content, in order to better watch movies on the TV, 16: 9 TV screen The proportion appears, and because the future of high-definition television will mainly use the ratio of 16: 9, so there are some LCD TV use of such a screen ratio.
