Change CMA output resolution

I posted this as a question in the general discussion forum so hopefully I'll find out if there is a way to change the CMA resolution but if not here's the problem.

The CMA output resolution seems to be fixed at 1280x1024.

I have a rack mount Keboard/mouse/monitor that only supports up to 1024x768.

1280 seems to be way overkill as the Windows MMC and DMX viewer dont need nearly that much real-estate (I don't think you can even expand MMC past 1024 pixels.)

There's got to be a very simple way to implement this, right?
