So, I upgraded my setup from 2 Benq 20.1" to 2 Acer 21.5" (better resolution, and they were cheap on newegg). So I'm selling one of the monitors in a package deal to my dad (with a comp) and the other went to my girlfriend so she can have 2 monitors. She has an old HP running XP MCE, it has an AGP FX 5200 with VGA and DVI outs. I assumed (perhaps incorrectly) that that meant she could run 2 monitors like I do. It seems she can only clone or expand (horizontally or vertically) the desktop instead of extending. Expanding wouldn't be too bad, except that both of the monitors she has are different resolution. So extending is really the only usable option. Is the FX 5200 just incapable of doing that? I think this is something that should be handled outside of the Nvidia Control Panel, since in every computer I've seen a display 'extended' on was able do do that just in the regular display properties. I have at my disposal a PCI Radeon 7000 with VGA and DVI and a AGP GF 7800GS. I don't know if the 7000 will do what we want, and I know the 7800 will, but I don't think the 7800 will fit in the HP case, and it seems unlikely the HP PSU will survive very long with the 7800 in there. So before I go through cleaning out the Nvidia drivers to install a PCI 7000, I'd like to see if anyone knows if its a physical limitation of the card.
