Hi,

I have two display ports in system. Based on the ports ID i need to clone or extend the displays Programatically in C++.

Is any one have an idea how to clone and extend the displays? Do we have any Windows API to do it?

I have used 'EnumDisplayDevices() function to get the display info but am not getting to extend or clone the display.

Any help would be appreciated.

You are nearby, but changing should do ChangeDisplaySettingsExW .

Read the documentation carefully to get it work.

Using the EnumDisplayDevices() function i will get the DeviceID information using that i need to change to either Extended or Cloned.

So based on the DeviceID i need to decide which one to make it cloned and Extended.

Do we have any API which takes the Device ID as input and change the setting?
