Aspect Ratio is the shape of the image, determined by the width of the image divided by the height. The three most common projector Aspect Ratios are 4:3, 16:10, and 16:9.
4:3 is known as “Standard Format” and is close to a square. Older computers and TVs are often 4:3.
16:10 is a type of widescreen. It can be found on laptops and computer monitors.
16:9 is the more common type of widescreen. It is somewhat taller than 16:10. It is used by most HDTVs and many laptops, and Infocus interactive displays.
The native Aspect Ratio of a projector is the shape of the image it produces by default. Most projectors can display content in multiple Aspect Ratios (check the manual or user guide for details). When displaying content in a non-native Aspect Ratio, some light will still reach the screen on the edges of the projected image.
The native Aspect Ratio of an interactive display is the shape of the screen. When content of a different Aspect Ratio is displayed, it will not fill the full screen.
If the content’s Aspect Ratio is wider than the native, there will be bars above and below the image. If the content’s Aspect Ratio is narrower than the native, there will be bars on the left and right.
