Description:
display switcher for attaching/detaching displays easily
No more headaches just before your presentation. Disper lets you add and remove display devices at the press of a button. It detects what display devices are attached at the moment, and configures the display output automatically. You can specify whether to clone the output on all displays, or to extend the desktop.
