Operation
Once the USB Display Adapter has been installed on the
Host Computer, the Display Device(s) (and audio controller, if
applicable) will operate within Windows the same as a Display
Device connected directly to the Host Computer’s Graphics
Controller.
This section of the manual outlines the full array of Windows
conguration options associated to the USB Display Adapter.
Display Conguration
Identifying Display Devices Within Windows Display
Settings
Windows assigns Display Numbers to each connected Display
Device, so that users can identify and dierentiate each monitor.
This is useful to understand the order and arrangement of each
connected monitor, especially when multiple Display Devices
are connected to the Host Computer.
The numbers assigned to the monitors indicate their position
in the monitor arrangement. The primary monitor is typically
assigned the number “1,” and additional monitors are assigned
subsequent numbers like “2,”“3,” and so on. These numbers help
Windows identify which monitor users are referring to when
making changes or adjustments in display settings.

To identify which number is assigned to each connected
Display Device within Windows:
1. Right-Click anywhere on the Windows Desktop and select
Display Settings.
2. This will open the Windows Settings app to the Display
tab. Below Select a display to change the settings for it,
you will see a diagram representing the current monitor
arrangement and the Display Number assigned to each
monitor.

Conguring Display Devices for an Extended Windows
Desktop
Extending the Windows Desktop provides users with the ability
to expand their workspace across multiple monitors. The mouse
cursor can edge-scroll between each monitor and use them as
an extension of the primary monitor.
With extended desktops, users have more screen real estate
to work with and can have dierent applications, documents,
or windows open on each monitor. This makes it easier to
multi-task, compare information, or work on multiple projects
simultaneously.
To congure a Display Device as an extended Windows
Desktop:
1. Right-Click anywhere on the Windows Desktop and select
Display Settings.

3. Click the Display Number that corresponds to the monitor
that will be congured for Extended Windows Desktop. The
selected monitor will become highlighted.
Note: It’s possible that two numbers may appear within
the same monitor block. This indicates that the monitors
are currently congured for a mirror conguration. If the
desired Display Number appears within the same monitor
block as another number, simply select that monitor block
which contains the desired Display Number.
