Has anyone set up four monitors under WinXP SP3 on a Dell PC? I got a request yesterday for this from one of my users and my IT guy gave me a deer in the headlights look when I asked him if it was possible. I Googled but didn't find anything other than there is an NVidia quadro NVS 420 card option available for the Dell 780 that we have but not whether it's supported by WinXP or just by Win7.
