MacPro Leopard 10.5.2, Problems with the Quadro FX 4500 card. It has dual DVI ports. It'll run 2 DVI devices when it's DVI to DVI, but it won't run the same two screens if they go via VGA (both DVI ports having a DVI to VGA adapter). The second port (port 2) has the screen detected in the Displays System Preferences but the screen never lights up. Yes, I know all about DVI extenders, etc; I need the VGA to work.
