Just to be sure (because if you're using DVI-D, the video card should have no impact on the image as the D to A conversion happens in the monitor) have you double checked all of the preference settings in SVII to make sure they all match the old laptop? Also, are you connecting the puck directly to a USB port on the computer (not to a USB hub, or to the monitor)? One more question, when SVII is going through the motions, does it look the same as it did with the laptop (does the screen first flash a few funky colors, then crank the luminance)? One possibility is that your laptop doesn't support DDC/ci. I've heard of this happening with some laptops that have Intel integrated graphics cards. NEC has since come up with a workaround for such machines but it's only available with the newer PA series monitors (basically SV talks to the monitor via USB instead of DDC/ci over the monitor cable).
Sorry I didn't answer your direct question, but I'm wondering if it's possible to avoid having to go there.
