Aspect Ratio Management

Aspect Ratio Management

The Aspect Ratio is the ratio of the pixel width of your display to the hieght of the display. Commonly you'll see it listed as a number (1.25 or 0.8) or as a ratio (5:4). Knowing your display's aspect ratio can help you optimize your visual display for a more balanced and less skewed graphical presentation.

OFP is rather unique in that it has excellent support for arbitrary display resolutions and aspect ratios. The process is not automatic though, and requires some manipulation of the userinfo.cfg file.
