Getting the type of GPU connection in Windows XP?

Question

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

I found two ways to do this:

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

but both are only supported on Windows Vista or higher.

There must be a way in XP to do this, but after a long search I just can't find it, and it becomes very relevant when I find a way.

Any ideas?

Perhaps you can use the EnumDisplayDevices link ( for MSDN ) and analyze some of the data as described here . This mainly concerns the comparison of physical displays with logical ones.
