DisplaySwitcher
Switch monitor inputs and transfer text and files between computers
DisplaySwitcher lets you switch a monitor’s video input with a software button and transfer text and files between Linux, macOS, and Windows computers. If one computer can’t switch the monitor directly, another connected computer that can switch it will perform the action.
You can transfer text and files using cut-and-paste, drag-and-drop, or file browsing across operating systems. No network or firewall configuration is needed.
It’s designed for developers, IT professionals, and home office users working with multiple computers. The cost is $5.95 per month with a one-month free trial.
