Monitor Alignment Off To The Right

Hello,
I'm a total Newbie running OpenSuSE 10.3 64bit.
After installing Suse the Display of my monitor is off to the right. I tried going into Yast and Monitor settings and did the "test" thing with saxt2?, but it doesn't remember my settings.
I had 10.2 installed for a short while before installing 10.3 and during the install of 10.2 I was asked about my monitors settings and I could set the alignment up there. But 10.3 didn't do that. I can only press the Auto/Set on button the monitor to correct this.
But when I boot into Windows, it's off again.
Is there any way, I can correct the monitor alignment in Suse?
Many thanks
