KScreen is the screen management software for KDE Plasma Workspaces which tries to be as magic and automatic as possible for users with basic needs and easy to configure for those who want special setups.
KScreen is part of Plasma releases.
Please contact the support channels of your Linux distribution for user support first. If you encounter a bug you can report it at the KDE bug tracker (first look for duplicates).
