Display and Peripheral Manager on Mac User’s Guide

Restoring application positions 27
To go back to a favorite layout, first select Save current window layout and then
Restore saved window layout.
You may use monitors with different models or resolutions in your daily routine, and
you may apply different window layouts on them. Dell Display and Peripheral
Manager registers 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 connected.
NOTE: You should keep your applications running in order to benefit
from this feature. Dell Display and Peripheral Manager does not launch
applications.
