How can I get monitors numbers from Screen Resolution dialog in win7 programmatically?

Question

When you press Identify button in Screen Resolution dialog then Windows shows you big white monitor numbers on each monitor. It was easy to find them programmatically togeth

Answer 1

Windows does not provide a function that allows applications to obtain the numbers used by the display settings app. The numbers themselves are specific only to the display settings app and have no meaning in the system or in the CCD APIs used to query/set the display topology.

The best option is for applications to define their own criteria for assigning an index when prompting the user to select a display.
