Keep Setting After Reset
When checked, the virtual display configuration will be maintained after a soft
reset. When not checked settings will return to the factory defaults after a soft
reset. WARNING: PRESERVE AFTER RESET SHOULD BE USED WITH
GREAT CAUTION. If you choose configuration settings that render your
device unusable, you will need to perform a HARD-RESET resulting in a
LOSS OF ALL DATA on your device. You should test the configuration
thoroughly before checking this option.
Swap Width and Height on Rotate
When checked, the virtual display width and height will be swapped
whenever the display is rotated by 90 degrees.

Save icon (floppy disk).

Notes:
1. Width and Height units are in pixels. Although these dimensions could
hypothetically be any value, keep in mind that large virtual displays will require
significant memory and may reduce system performance. If NVD cannot
accommodate the desired size upon startup, it will disable itself and reset the
system.
