You could create a monitor profile for each set of monitors you have enabled, and then see which one is auto detected though, not sure if that would do the same thing you're looking for. ]]> How to programmatically detect the number of monitors that are powered on https://www.displayfusion.com/Discussions/View/how-to-programmatically-detect-the-number-of-monitors-that-are-powered-on/?ID=019548b1-5301-7532-b37e-b00636def47e Thu, 27 Feb 2025 18:35:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/how-to-programmatically-detect-the-number-of-monitors-that-are-powered-on/?ID=019548b1-5301-7532-b37e-b00636def47e DisplayFusion Just curious if displayfusion has any type of way to Programmatically determine how many monitors are POWERED ON at a given moment. I would like to call this from an external application/script and see if I could leverage something in display fusion that could assist me in the monitor detection that i could then parse on my own to determine the powered on count so i can then do custom actions based on which monitors are powerd on at run time of the code.

EG: DF.exe /getMonitorCount

Detected:
Monitor 1 Dell XYZ
Monitor 2 Samung PDQ

Then to test this I would turn off one monitor and run the above again

EG: DF.exe /getMonitorCount

Detected:
Monitor 1 Dell XYZ

If not display fusion then could someone recommend something that could do this type of approach?

thanks ]]>
