| Restoring Application Positions
You may use monitors with different models or resolutions in your daily routine,
and you may apply different window layouts on them. DDM is able to know the
monitor you have reconnected and restore application positions accordingly. In case
you need to replace a monitor in a monitor matrix configuration, you can save the
window layout before replacement and restore the layout after a new monitor is
installed.
NOTE: You should keep your applications running in order to benefit
from this feature. DDM does not launch applications.
