Not getting into why such a thing would want to be done in the first place… just wondering if such a thing is possible. Just to be clear, this would be a transparent window with the WS_EX_LAYERED flag, stretched across more than 1 monitor.
thanks,

Of course it can – otherwise it would be broken to drag-move a layered window between two monitors. While it’s on both monitors, the window looks normal on both displays.
