If you can find an adapter from SVideo to VGA, it should work, but not certain if the SVideo outs on the GeForce MX cards are passthrough or separable signals. Check the information and specification for the Geforce4 MX 440 to see if it's possible. If it says it can handle a monitor on VGA and another on SVideo for dual-view, then go for it (this may also be enumerated in the nView PDF - I'll check it shortly). Nope, you can have one AGP card and another PCI card with different monitors hooked up and nView will let you clone and extend between them. You can mix cards sometimes (nVidia, ATI, Matrox), but it can get tricky. The recommendation is to use two cards with the same chipset (GeForce4 and GeForce4). The other recommendation is that the PCI card be in the first PCI slot after the AGP card. BYS
