I have a desktop which is wired to 2 areas -- a display at my desk, and a TV in the living room.

I have 2 profiles set to display on either the desktop or on my TV (I never use both at the same time), and I have a shortcut set to switch between them (Ctrl + Shift + Alt + Arrow Key) and this works fine when logged in.

However, the primary use case of this setup is to swap the display when I am sat on the couch using my wireless keyboard (or back to my desk when I am sat there) and I usually want to do that right when the computer starts up (if I am sat on the couch and the display is over on my desk it is hard to get past the lock screen)

It seems I cannot use my shortcuts when the screen is locked, does anyone know of any workarounds for this?
