Unigine.Displays Class
The Displays class allows getting information about connected displays such as the number of screen displays and the index of the main one, their position and size in pixels. It provides access to the name and current dpi. This class also allows obtaining the total number of available modes for displays and getting the resolution and refresh rate by the mode index.
