Portable NirSoft utility for enabling, disabling and configuring multiple monitors.
MultiMonitorTool saves and reloads monitor configurations and is scriptable from the command line, but is closed-source freeware with a dated interface.
DisplayMagician

DisplayMagician switches display and audio setups when launching an application and can restore them afterwards, and is open source under GPL-3.0 instead of MIT.
