DisplayLink driver must be installed on your computer host to communicate with the QZ DisplayLink device. Download the latest DisplayLink driver suitable to your host computer here: https://www.synaptics.com/products/displaylink-graphics/downloads

macOS requires the user to permit "Screen Recording" for DisplayLink driver to work properly. Approving it enables the DisplayLink to access the pixels it needs to render a mirrored or extended screen and send the pixels over USB from your computer to the DisplayLink display. DisplayLink Manager does not send any data or pixels back to DisplayLink/Synaptics.

User is notified about a need for Screen Recording permission in three places.

1. By macOS dialog box on first DisplayLink device plug-in

2. By DisplayLink driver on each device plug-in

3. By DisplayLink Manager app warning in macOS status bar

To approve the permission, please follow these steps:

1. Open System Settings;

2. Go to Privacy & Security > Screen Recording;

3. From Screen Recording tab toggle DisplayLink Manager;

4. Authenticate the changes by using your login details;

5. Click Quit & Reopen.

Once permissions are granted a new icon will show up in the macOS status bar.

Latest Computer Technologies How to setup Triple Display on your Windows laptop using QZ Thunderbolt 4 HB91/HB92 or USB-C HB71 Docking Station https://www.qzonline.in/how-to-setup-triple-display-on-your-windows-laptop-using-qz-thunderbolt-4-hb91-hb92-or-usb-c-hb71-docking-station/ 10/24/2024 QZ Thunderbolt 4 Docking Station QZ-HB91 supports max 3 video streams supported simultaneously.

Max one 8K/30Hz or two 4K/60Hz or three 4K/60Hz+4K/60Hz+4K/30Hz with different pictures in MST mode on windows system. Video capabilities are dependent on the host.

Note: No external drivers required. QZ Docks are plug and play.

When you connect multiple monitors to your Dell computer, Windows automatically detects the monitor and displays your computer desktop screen. You can then choose how you want your desktop screen to appear and customize the display settings such as display style, screen resolution, color depth, and more. Windows 11, Windows 10, or Windows 8 or 8.1 support multiple monitor setup.

Before you begin, see the documentation of your computer and your monitor to determine what video connections they have in common, such as VGA, HDMI, Mini DisplayPort or DisplayPort (DP), and whether your monitor supports DisplayPort Multi-Stream Transport (MST).

Knowing if your monitors support MST tells you if the monitor supports daisy chain using DisplayPort cables or if you must use two different kinds of video cables.

When you know what connections they have in common and whether your monitor supports DisplayPort Multi-Stream Transport (MST), you must acquire the needed cables to be able to connect the monitors to the computer.

1. For optimum performance, it is recommended that you install the latest drivers on your computer.

Ensure that your computer has the latest updates for Windows. Go to the Windows Update website to be sure that your computer is fully updated.

2. Depending on your monitors and their features, you have two options, as outlined previously.

2a. When your monitor supports DisplayPort Multi-Stream Transport (MST), perform the following steps.
Using the correct cable to connect to your QZ dock to the DisplayPort In to the first monitor.
Using another cable, connect the DisplayPort Out connection on the first monitor to the DisplayPort In connection on the second monitor.
NOTE: To daisy chain more than two monitors, follow a similar sequence: The first monitor connects to the second, the second monitor connects to the third.

Using the On-Screen Display (OSD) menu on your monitor, set the MST to On
Ensure that the last monitor in the chain has MST set to Off.

2b. When your monitor does not support DisplayPort Multi-Stream Transport (MST), perform the following steps:
Connect a video cable from your QZ dock to the first monitor.
Connect a video cable from your QZ dock to the second monitor

3. After connecting the monitors, you can adjust the settings for each one.

3a. Arrange your displays
If you have multiple displays, you can rearrange them. This is useful if you want your displays to look the same as they do in your home or office. Select and drag the display to the wanted location in Display settings. When you are satisfied with the layout, click Apply. Move your mouse pointer across the different displays to ensure that your new layout works as expected.

You will see this option when Windows detects more than one display. Each display is numbered to help you identify them more easily.

3b. Select the primary display
In a multiple display setup, one display or monitor must be set as the primary display. The primary display shows the taskbar and other main desktop components such as time, system tray icons, and more. To set the primary and secondary displays, follow these steps:

Press the shortcut keys Windows logo + R keys to launch the Run dialog box.
In the Run dialog box, type desk.cpl and press Enter.
In the Display settings panel, select the display you want use as the primary display.
Under the Multiple Displays section, click to select the Make this my main display.
Click Keep changes when the pop-up dialog box appears.

3c. Change display options
After connecting your external monitors, you can change settings such as resolution, screen layout, and more.
To see the available settings in Windows 11 or Windows 10, go to the Settings app, select System, and then choose Display.

3d. Change orientation
Windows will recommend an orientation for your screen. To change it in Windows 11 or Windows 10, in the Display settings, under Scale & layout, select your preferred Display orientation.

NOTE: If you change the orientation of a monitor, you will also need to physically rotate the screen. For example, you would rotate your external display to use it in portrait instead of landscape.

3e. Choose a display option or display style
Once the cables are connected securely, your computer should automatically detect and display the desktop screen on the connected monitors. You can now select the display style that best suits your needs. Windows provides multiple display style options on how the desktop screen is displayed across multiple monitors that are connected to your computer.

NOTE: To change what shows on your displays, press Windows logo key + P. Here is what you can choose.

See things on one display only > PC screen only
See the same thing on all your displays > Duplicate
See your desktop across multiple screens. When you have displays extended, you can move items between the two screens > Extend
See everything on the second display only > Second screen only

NOTE: When you connect an external monitor to a Dell laptop, the default display style is set to Duplicate. When you connect a second or third monitor to a Dell desktop, the default display style is set to Extend.
