The computer's ability to reorganize windows is independent of whether the monitor is on or off. For outputs like HDMI we don't even know if it's on or of, we only know whether the cable is connected.

What you're complaining about is entirely a software problem. No improvements to display standards will move the situation forward.

By the way, if you're using Linux, consider switching your desktop environment.

I am pretty sure that HDMI CEC has a way to enumerate the connected devices and see if there's anyone alive on the other end of a cable. Assuming the other end also does CEC.

Now, if only we could convince PC graphics manufacturers to support CEC instead of ignoring it. It seems the only people who do care are the little set-top boxes that run Nvidia Tegra or Qualcomm chips.

DDC might tell you that. On the other hand it is also good. Avoids that the OS moves windows around.
