A geom string is a special configuration setting in Eternity which allows specification of all of the characteristics of a video mode in a single string.
The syntax of a geom string is as follows:
Where WWWW is the width, between 320 and 2560; HHHH is the height, between 200 and 1600; and [flags] is an optional valid combination of the following single-letter specifiers:
|w||Selects windowed mode.|
|f||Selects fullscreen mode.|
|a||Selects "asynchronous" or non-page-flipped updating.|
|v||Selects page-flipped updating.|
|s||Selects "software" surface.|
|h||Selects "hardware" surface (eg. DirectDraw acceleration)|
|n||Creates primary window without a window frame, where supported.|
The following are examples of valid geom strings.
