To force the game to run at a set resolution follow the steps below:
To change the resolution to a custom resolution you need to edit the ini file for the game.
- Browse to the installation directory (C:\program files\Firaxis games\Sid Meier's Civilization 4 by default)
- Double click on the file named _Civ4Config
- Browse through the file for the line:
- Screenheight = 0
- Screenwidth = 0
- Change these values to the ones you wish and save the file.
For example, changing the settings to:
- Screenheight = 1024
- Screenwidth = 768
......Will force the game into 1024x 768 mode
If you wish to use the default settings, change both options back to 0.
