You need either two video cards (one AGP, one PCI) or a card with dual outputs (DVI/VGA or VGA/VGA). Otherwise it won't be possible. If memory serves, the Geforce MX cards do not have multiple outputs. You need an AGP TI card (TI 4200, 4600) or an additional card in PCI (I have a Geforce4 TI 4600 AGP and Geforce4 MX 420 PCI). You will need to install the NVidia drivers again and both video cards (and attached monitors) should be seen in the Display Properties->Settings. You have to enable nView and go through the wizard for it before it works. Go to NVidia's site to get a PDF that explains the setup procedure and settings in detail. BYS
