soft15khz, Jpac, split screen

[Bramlet]

I installed soft15khz clicked 15khz, set resolution to 640 x 480, turned it off, plugged in the jpac, and my screen is split in half. If I plug it into my regular screen I can see the boot process but lose the signal once windows starts. The Jpac has a green and amber light and another green light on. What did I miss? I have 8500Gt so maybe I need the dongle? If that is it I guess I can swap out my current graphics or try integrated. Maybe I'm missing something. I installed a tiny xp, the drivers for the video card, sound card, and a wifi adapter. I installed mame and mala and made some lists in romlister that sort of work after deleting teamqb, I don't have a layout yet but, I put a shortcut to mala in the startup folder, I have it just log on the administrator without asking for password, there are no other accounts. I clicked the install 15 khz and rebooted and now I get the split screen thing for boot and once windows is loaded when plugged into the hantarex MTC900E via Jpac.

need to set resolution below 600 x480 to avoid split screens
