I’ve got 2 Spectrum 4K’s and use them for work, PC gaming, and console gaming and I’ve noticed that the inputs of the display all stay active even when the device is switched to another input.
For example, my PC is connected to both monitors and lets say monitor 1 is set as the primary display. Now I also have my PS5 connected to monitor 1. When I switch inputs on monitor 1 to the PS5, my gaming PC still sees monitor 1 and is outputting a signal to it.
If I power on the PS5 first and then boot the PC this results in the login screen being displayed on monitor 1 and I have to switch inputs or disconnect the DP cable.
Now I could swap displays and put the PS5 on monitor 2 to counter this, but the input is still active at this time and can have windows. You can still drag windows to this display even though you have changed the input. Keyboard shortcuts might move windows here.
I would like to see a firmware update address this input activity and make the inactive inputs actually be inactive so that windows and macOS stop registering them as being connected when the monitor is set to a different input.
