Can't get a VGA monitor to work alongside a DVI one (Gigabyte GA-B75M-D3P, Intel HD4000)

[Mephistopelus]

Hi,

I've got a build based on Gigabyte GA-B75M-D3P and Intel HD4000, working fine since 10.7. All this time I had only one (DVI) display connected, with no issues whatsoever. Today I tried to plug in a second monitor into a VGA/D-Sub port, and it didn't work:

Both monitors seemed to be working fine until I reached the log in screen. Then, the DVI one stayed on, but the VGA one started to show something like this:

I have "GraphicsEnabler" set to "Yes". Switching it to "No" prevented the system from loading.
Setting "PCIRootUID" to 0 or 1 didn't help either.

Is there a way to get the VGA one to work too?
Thanks a lot!

Real Macs do not have a VGA port, so VGA is not supported.

Thanks for your answer!
Is there a way to connect the VGA monitor using some kind of a converter/adapter to Display Port or HDMI?
