    The first link, i have tried, my pc connect two monitors,if i power off one monitor and keep its HDMI cable plugged in,when i test, both Monitors power status is PowerDeviceD0.
    Then if i power off one monitor and unplug HDMI cable,can only detect one monitor, how can i enum all monitors that have plugged in the pc?
    thanks

    Nice!

    >> how can i enum all monitors that have plugged in the pc?
    If it can be done, I don't know how. It may depend on particular HW and their drivers anyway. I would just write code to gather as much information as you can and start experimenting.

But I compared the registry difference, not find the relevant infomation.
