+.BI "int vga_guesstiming(int x, int y, int clue, int arg);
+
+.SH DESCRIPTION
+Calculates a timing line for a 
+.BR x*y
+resolution, according to the value of 
+.BR clue.
+
+.SH CALCULATION METHODS
+If 
+.BR clue
+is 0, then the aspect ratio for the requested mode (
+.BR x:y
+) must be 4:3. A mode with the same aspect ratio closest to the requested, while still having a higher resolution
+is found, and then scaled down to the requested mode.
+
+If 
+.BR clue
+is 1, then the aspect ratio for the requested mode (
+.BR x:y
+) must be 4:3. A mode with the same aspect ratio closest to the requested, while still having a lower resolution
+is found, and then scaled down to the requested mode.
