UltraMon is a utility for multi-monitor systems, designed to increase
productivity and unlock the full potential of multiple monitors.
*
Window management
Quickly move windows between monitors or maximize a window to the
desktop using the additional window buttons.
*
Smart Taskbar
An additional taskbar is added to each secondary monitor, and
each taskbar only shows tasks from the monitor it is on. This makes
managing lots of open applications much easier, and when activating an
application, you will know on which monitor it will appear.
*
Application positioning
Use the shortcut extension to set an application's position or
use custom display settings when the application is running. To
configure custom settings, right-click the shortcut and select
Properties from the menu.
*
Display profiles
With display profiles, you can quickly change the settings of one
or more monitors. You can also create a display profile that gets
applied when logging in, especially useful when the computer is used by
more than one person, and not everyone wants to use the same display
settings.
*
Desktop wallpaper
The wallpaper manager adds the ability to use a different picture
on each monitor, or stretch a single picture across the desktop.
*
Screen savers
Most screen savers only run on the primary monitor. The screen
saver manager can blank the secondary monitors when the screen saver is
running, or run additional screen savers on secondary monitors.
*
Mirroring
Mirror the primary monitor on one or more secondary monitors, for
example when doing a presentation. A unique feature is support for
different resolutions, the primary monitor can run at a higher
resolution for example.
