webtop 3.0 screen size fix?

[dnyc]

anyone know how to change the screen size while in webtop 3.0 on rooted razr stock ICS?
i have it plugged into a PC monitor which is square but webtop is configured for a rectangular phone or tablet, so the screen is letterboxed inside my monitor, with wasted/black space above and below so e.g. i can only see a limited number of lines at a time of an e-mail message
wondering if there's a way to change the screen dimensions so it uses whole screen (rather than letterbox or just stretching same rectangle vertically to fit square screen with no added usable space)
