GCII:ToA graphics issues

I had purchased and been playing GCII with the newest ToA expansion happily for some weeks, but I just recently changed monitors to a larger, widescreen HDTV LCD which I am using for a monitor among other uses.  It uses a non-standard resolution on my graphics card (1360x768) and GCII:ToA just hates it.  I start the program and eventually get an "Invalid Format" error on my monitor, indicating it's receiving a signal it can't display.  GC II, and GC II Dark Avatar have no issues, just ToA.  Any explanation for why ToA  _only_ is incapable of dealing with this resolution?  The only change of hardware is my monitor, I can always switch back to my other monitor, but I wanted to use the newer, larger screen to play.

Edit: well, nevermind now, found another post which told me how to edit the preferences for video resolution, which solved the issue.  Also posted this in the wrong forum, whoops.
