Can operating system switch display monitor to another cable input in XV271U?

I use two laptops, both are closed up and tucked away. I have both multi-device mouse and multi-device keyboard, so it's a quick switch when changing laptops, just touch the button on each input device. Concerning the display, I use two monitors - the same two monitors for each laptop, pseudo-simultaneously. That is, the inputs are both up and running on both monitors, always. They are a couple Acer XV271U monitors.

Currently, I can only switch inputs to monitors by using the menu switch at the rear of each monitor. Not fun, x2!

Can the monitor(s) get a signal from the operating system to switch over and use another input?

For instance, can I instruct Monitor 1 to now start displaying input from the DP signal input, or from HDMI input cable? Then change Monitor 2 to the other signal input? Without visiting the cumbersome menu from the back of each monitor! That would make the monitors behave as multi-device monitors, too.

If it can be done, how is it done? If it can't why not be the first to make it happen?

Thanks!

    You can try Auto mode. It should work. Any big large language model can give you the details.

    For it to work, you need a monitor that has the feature, which I think.you have (see the manual). Every modern operating system supports disabling the video signal.

    These features combined are sufficient to make it work.

    Thanks @Species8472 -

    Auto mode is great, auto mode works, but because it cannot read my mind and because I have multiple input signals at the same time, it cannot know what I want to do. Does not work for this scenario, although it's great if I were to shut down one of the laptops. However, both stay on for the second system to be available for another user to remote in.

    Thanks for thinking about this situation and responding!

    The "hard" part of your setup is this part, IMHO. The "easy" part is that you just need to do your operating system specific method of stopping with sending a video signal to the output of your choice. This can be done via xset dpms force off on Linux. Now, as for the "reading your mind" part, that's just detecting keyboard input or mouse input, which under Linux would also be a trivial script that could be run as a system service. The system service could send a message to your other computer to turn off the outputs of interest. That way, your monitors will only get the right signals and it would all just work.

    I think more people would be interested in a polished version of this, especially if it were open-source and multi-platform.

    The "reading your mind" part can also be implemented via a Windows Hello kind of feature, which also exists on Linux, btw. It could also be implemented with a cheap mm-wave radar for the chair you are sitting on, etc. You could also just switch by clapping your hands. Really, endless possibilities.
