I have a Wacom Cintiq Pro 13 pen display that I use as a secondary monitor. When on, I "project" it as Extended. I even use it as my "primary monitor" to ensure the touch and pen features function on it and not on the 27in screen I normally use as my "real" main display. The problem is that when I turn off the monitor (which is necessary when I slide it out of the way to make space on desk) Windows does not detect that it is off (unless I physically unplug it everytime) and therefore persists to have apps and windows open in the other desktop space where there is no screen of anymore. This is not a problem for displayport cables and maybe even some hdmi situations. However My situation is that this Pen display is linked via DisplayPort over USB-C as Thunderbolt 3 protocol through a usb-c port on my discrete graphics card (motherboard usb c port does not support thunderbolt 3).
Long story short. I want to be able to press the power button on my pen display and automatically have windows "project" as PC Screen Only for my real 27in main monitor.
Relevant Specs: OS: Windows 10 Home
GPU: Asus RTX 2080 Ti
Motherboard: Asus Maximus XI Gene
Pen Display: Wacom Cintiq Pro 13
Also just in-case: For some reason USB Selective-Suspend does not work with my motherboard and windows 10 combo, I've tried troubleshooting that for many hours for other reasons to no avail. So... not that.
Thank you for any of your time and consideration
