Try holding down the CTRL key on the keyboard when logging in, that will disable most graphics settings and log you into "FORCE LOW-RES" mode. That may make it easier to see your settings.

Second thing to try is to delete (or temporarily rename) the settings file, which is at

C:\Users\(YourUserName)\AppData\LocalLow\Elder Game\Project Gorgon\GorgonConfig.txt

If you delete this file (while the game isn't running), the game will recreate it with defaults the next time you log in.
