Everything works fine with the above configuration. However, I wanted to use DVI with my secondary display as well. So I bought a DVI Splitter Cable.
So, I hooked it up. Usually, when I boot up my pc the boot loader and boot screen only shows up on my primary display and on the secondary display it just says 'this video mode is not supported'.
However, this time the boot loader and boot screen showed up on both displays. Unfortunately, when it came time for the Windows XP welcome screen both displays go blank.
I don't understand why this happens, anyone got any ideas how I can fix this?
