The aspect ratio is the ratio of the horizontal dimension (width) to the vertical dimension (height) of a screen. It is expressed as "width : height."
The following aspect ratios are normally used in Computer or AV equipment.
[4:3]
The aspect ratio for SXGA+ (1400 x 1050) and XGA (1024 x 768) display resolution in PC or for the traditional television screen.
The aspect ratio for this projector is 4:3.
[5:4]
The aspect ratio for SXGA (1280 x 1024) display resolution.
[16:9]
The aspect ratio for the high resolution digital television or digital terrestrial broadcasting.
For the aspect ratio for movie screens, "vista vision size" and "cinema scope size", etc. are used.

This process is called the tracking. This projector can display an image properly by automatically adjust the tracking with the auto PC adjustment function even if there is a small difference in the synchronization signal from an analog imaging device.
