Add your monitors, review the detected inputs, and save. For grouped actions, choose an input for every monitor. See profiles and shortcuts. Back up your settings and quit the app before upgrading.
Monitor support varies, and advertised inputs can be incomplete. Linux testing has focused on CachyOS/KDE; physical Windows testing is limited. Intel/NVIDIA raw-I²C Windows backends and macOS remain future work. Use known input codes for your monitor; commands are sent directly to the display.
For troubleshooting, open Diagnostics → Create report, review it, then copy or save it with your issue. Reports stay local until you share them. Check for app updates in Preferences → Application updates.
