Running in 1920x450 from Boot

Hi all - hope you can help, I have a monitor that is 1920x450 when trying to run Acronis2010 from boot I can only see half of the screen as my screen cuts of the bottom part of Acronis.

I am not able to plug in another monitor to boot from, is there a script or something I can do to boot up Acronis into this resolution? or another resolution where I can see the whole screen?

Have got around this by guessing where the mouse pointer should be.. as you can imagine, its a PAIN!

thanks
