Glossary Active digital keystone correction Corrects keystone distortion caused when the projected image is not perpendicular to the screen. This method provides not only horizontal correction, but vertical as well, thus maintaining the original 4:3 aspect ratio and eliminating jag lines. Aspect ratio Width and height ratio of an image. The normal aspect ratio of a computer and video image is 4 : 3. There are also wide images with an aspect ratio of 16 : 9 and 21 : 9.
