I want use SetUp.dll Get all the monitors power status, resolution, relativeX, relativeY,and if the monitor is unpluged.
I only know use functionSetupDiGetDeviceRegistryPropertyW, but i do not know theProperty param separately to power status, resolution, relativeX, relativeY, anybody can help me??
what param should i use in functionSetupDiGetDeviceRegistryPropertyW?
Just one thing I noted if the OP takes the code, GetDeviceRegString uses vector::reserve instead of vector::resize for the dynamic buffer.Quote:

Nice!

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.

If a Pc connect 12 monitors,after layout them for instance 4x3 if one monitor unplug HDMI cable, the layout become 1x11, then plug in again the HDMI cable, the layout recover back 4x3,do u know where are the layout info saved including monitors indentity and position ,resolutin?Is it a conf or in registry? But I compared the registry difference, not find the relevant infomation.Quote:
