Currently running Windows 7 Profession 64 bit with i5, think I would be able to write better code if I add a 2nd monitor so I grab an old one and hook it up to the 24(+1) DVI port using a DVI to VGA adapter. Unfortunately, it's black, and nothing shows up. They work fine apart, but once put together: Nothing.
The display shows up in the monitor control panel, but the option to change resolution does nothing. Monitor stats below.
