Hi,
This is gonna be a tricky question but hoping there's an answer for it.
Basically, we have a computer setup in our school's hall which is connected to a projector and sound system. Every now and then, our teachers use the hall for meetings/training sessions etc and they like to use their laptops, instead of the dedicated PC I setup there. They unplug all the cables to plug into their laptops and then leave them unplugged when they're finished. It's driving me mad everytime I have to go plug all the cables back in.
I wanted to know if there was some kind of wall plate where I can plug the dedicated PC into the "default" ports, and the input ports on the faceplate act as a signal overrider.
Say if the PC was on and outputting its desktop to the projector via the faceplate, a teacher then plugs their laptop in the available input port, the projector then shows the teacher's laptop desktop.
I know it's a dumb question and probably no answer to it but I'm sick of getting told off because "the sound isn't working" for their assembly.
