Use DDC to switch monitor inputs

Recommended Posts

Display Data Channel ( https://en.wikipedia.org/wiki/Display_Data_Channel ) can be used to switch monitor inputs on most monitors.  Discussion on AutoHotKey for automating this: https://autohotkey.com/board/topic/96884-change-monitor-input-source/ .

Essentially, I want to be able to use Synergy as a true software KVM.

It appears that this was brought up before here: 

But lacked technical detail.


This problem could also be solved by a config option that runs a script on hotkey press.

I've been using Synergy 1 with AutoHotKey to get this working: https://moshen.net/posts/virtual_kvm/

Oh boy this would be an awesome feature.

I use Synergy on 2 different computers but with the same monitor. Whenever I switch, I have to change the input manually (I know I can achieve this using scripts but I must admit that I'm lazy)
