PTterminal horizontal positioning

I have taken a Propeller Demo board and loaded PTterminal firm in order to make a dumb terminal for other projects. I have confirmed that the standard download is working properly in all aspects.
The problem is that the VGA I am using is rather annoying and temperamental. It automatically senses the video dimensions and seems to only recognize 640x480 at 69.xx HZ for the existing firmware. But I believe that the PTterminal package is set up for a higher resolution, 1024 X 786.
It would not be a problem, except that I have about 10 columns of the 80 column width pushed far to the left and hidden from view.
I have pondered modifying the code to make the monitor provide a properly centered image, but I am unsure of the right tactic.
1. Do I reconfigure the software for a 100 column screen and have 10 or more columns remain blank on the left in order to get an 80 character display?
2. Do I bring the resolution of the software down to fit what the monitor wants to do?
3. Do I customize the video configurations to somehow make the VGA recognize the right screen dimensions and center itself?
4. Is there an alternative I haven't thought of?
5. Should I go to the PTterminal support and not bother Parallax? (I didn't buy their board.)
The monitor is my oldest working VGA and has long been rather problematic. Once a year I have to open it and wash the video board as soot from the air accumulates on the board and makes the video go completely haywire. (It has just had a complete annual cleaning.) Also, the manufacturer, Lemel, is a rather second rate OEM in Taiwan that seems to use its brand to market what other more reliable brands have turned down.
The firmware will NOT allow me to select the resolution - just auto-sensing.
