I have been doing this for years without any additional software: just make sure your monitor goes to blank when locking the screen:

1. lock screen

2. Switch USB switch to the other source

3. Press space to activate the other PC

4. Monitor should automatically sitch to the "new" active source.

What monitors have worked for this for you? My Samsung monitor seems to have a hard time finding the source I want.

BenQs have it (look for "Input Auto Switch").
