It is possible to use the ‘Gather Windows’ button to bring all the ‘Display Preferences’ windows onto the main display.

To change the display’s resolution, select an available resolution from the Display Preferences window of the display you wish to change:

If you wish to rotate your display, you can configure the orientation using the ‘Rotate’ drop down. Select the appropriate angle of rotation to match your display’s set up.

For Apple M1 on macOS 12 Monterey and higher please follow DisplayLink Manager App Rotation for Apple M1 on macOS 12+.

If your computer is connected to more than two displays, you can specify that some are mirrored displays and others show the extended desktop. A mirrored display shows the same content as the main display whereas an extended display will be an extension to your existing desktop. You can arrange your displays so that they match the physical layout of your displays by selecting the ‘Arrangement’ pane within Display Preferences. This ensures that you can easily navigate between all connected displays.

When in Mirror mode, additional displays will display what is being shown on the primary display. Checking the “Mirror Display” on the ‘Arrangement’ pane enables this feature.

In MacOS Ventura and newer select the monitor you wish to mirror and select the option in the Use as

section. This expands and you can select to mirror the monitor.

To extend connected display, make sure to select "Stop Mirroring" under Use as section.

To work with both extended and mirrored displays, turn off mirroring then in the Arrangement pane press and hold 'cmd' and 'alt' and drag and drop the display you wish to mirror over the primary display. Repeat this with each display you wish to mirror, those untouched will remain extending.

Select each monitor and select the desired option under Use as section and specify if you want to mirror or extend each of the monitors.

You can change which is the main display by moving the Menu Bar between displays. Changing the main display affects where new windows appear and the position of the Dock. The ‘Menu Bar’ can be moved so that it is shown on an alternative display. Clicking the white menu bar and dragging it to the desired display will perform this action.
