To configure the display settings and monitor positions, bring up the Displays
Preferences from the System Preferences menu:
The Display settings for each display will appear on the individual monitors
themselves. To configure them all from a single location, press the “Gather Windows”
button and each screen’s Displays Preferences windows will appear on that display.
All supported video resolutions will appear in the list on the left side. To change the
positioning of each display, click on the “Arrangement“ button (found only on the
primary display) and you can then virtually reposition each display.
Using the Adapter in Extended or Mirror Mode
By default the USB Display Adapter will be setup as an extended display. To change
the display as a mirrored/cloned display, check the “Mirror Display” box on the
“Arrangement” page for that monitors Displays settings window. To return the monitor
to an extended display, uncheck this option.
To use both extended and mirrored displays simultaneously, turn off mirroring then in
the “Arrangement” page press and hold the ‘cmd’ and ‘alt’ keys and drag and drop the
display you wish to mirror over the primary display (shown with the white bar).
Repeat this with each display you wish to mirror, all others will act as an
extended display.
