How can I find out what graphic card a screen is connected to in C#?

Question

I need to programatically find out what graphic card a screen is connected to using C#. This information is visible in DxDiag, speccy and even in windows advanced display settings view:

But how can I do this in C# myself?

Answer 1

The following is code by @NielW in C# detect which graphics card drives video

  ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_VideoController");
  foreach (ManagementObject mo in searcher.Get())
  {
    PropertyData currentBitsPerPixel = mo.Properties["CurrentBitsPerPixel"];
    PropertyData description = mo.Properties["Description"];
    if (currentBitsPerPixel != null && description != null)
    {
      if (currentBitsPerPixel.Value != null)
        System.Console.WriteLine(description.Value);
      }
    }
  }

There is a long talk in the link because they have issues getting multiples graphic cards' names. But this code should work and it shows all names of available graphic cards.
