Getting the GPU connection type in Windows XP?

Question

I need to detect in code (C++) how the graphics card is connected to the monitor/s, i.e. vga or dvi etc.

I found two ways that I could do this:

• by querying the Windows Management Instrumentation for D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY or
• using the nVidia API function NvAPI_DISP_GetMonitorCapabilities,

but both of these are only supported in Windows Vista or higher.

There must surely be a way of doing this in XP, but after much searching I just can't find one and it's becoming quite urgent that I find a way.

Any ideas?

Possibly you can use EnumDisplayDevices (link to MSDN) and parse some informations as described here. It's basically about matching physical displays with logical ones.
