I have multiple monitors set up on an nvidia card using horizontal stretch, but one of the monitors is taller than the other and the windows are shifted when I move them in the middle. There there a way to shrink the size of the tall LCD monitor a little (leaving a black bar on the bottom) to align the picture for the multiple monitor setup?

I can't find any size settings in the Nvidia control panel. I remember ATI had size settings though, beyond resolution, where it actually let you adjust the picture stretch size for the monitor itself and create black bars around it.
