DisplaySwitcher

DisplaySwitcher is a desktop application for Linux, macOS, and Windows that combines monitor input switching with text and file transfers between computers. Switch a monitor’s video input with a software button instead of reaching for its physical controls. If one computer cannot switch the monitor directly, another connected computer capable of switching it can perform the action. Transfer text and files using cut-and-paste, drag-and-drop, or file browsing. No network or firewall configuration necessary. $5.95 per month with a one-month free trial.
