From click here, it suggests the following about resolution settings:
"Changing Your Resolution Settings.
It may be necessary to run the game with a different Compatibility mode setting. (It will be necessary to close the game before trying these steps.) To do this:
1. Right-click the shortcut icon for your game (if you don't use a shortcut, right click the .exe file). 2. Click Properties. 3. Click the Compatibility tab. 4. Click the box to run your game in 640 x 480 resolution. 5. Click OK.
There may also be settings on your monitor itself that are affecting how your games display. Try using the monitor buttons to look for a display setting with options such as 1:1, Aspect, & Fill. Based on the resolution you have your monitor set to, it may or may not be possible to alter those settings. When you run at a very high resolution, your monitor knows what aspect ratio it is capable of displaying."
In step 4. above, try a 1440*900 resolution setting if possible. Try a few other resolution settings as well.
What's the native resolution (NR) of your monitor? The NR may be the resolution you'd normally run it in when in Windows. Is it a widescreen model? G
