Native Aspect Ratio
Native Aspect Ratio refers to the dimensions of the display of a television. It measures the units wide, by the units high. The two standard measurements for flat panel televisions and various types of projectors are 4:3 and 16:9. 4:3 produces a traditional square display. 16:9 produces a rectangular, wide screen display. One ratio is not necessarily better than the other. It all depends on the preferences of the consumer.
