I have a 3 monitor setup - a laptop, and 2 monitors, both connected to a docking station. When I select the System Display settings, the external monitors both turn on but show the same content as if they are the same monitor, but the display settings only show 2 screens (the monitors both detected as number 2 and the laptop as number 1). How can I get them to all work together?

    To resolve the issue where both external monitors are displaying the same content and are detected as the same monitor, you can try the following steps:

    1. Check Docking Station Compatibility: Ensure that your docking station supports multiple displays and is compatible with your laptop. Some docking stations may have limitations on the number of displays they can handle simultaneously.
    2. Use DisplayPort MST: If your monitors support DisplayPort 1.2 and Multi-Stream Transport (MST), you can daisy chain them. Connect your laptop to the first monitor using the DisplayPort-In connection, and then connect the DisplayPort-Out of the first monitor to the DisplayPort-In of the second monitor. Make sure to enable DisplayPort 1.2 in the monitor's settings.
    3. Adjust Display Settings in Windows: Go to the display settings in Windows:
      • Right-click on the desktop and select Display settings.
      • Scroll down to Multiple displays and select Extend these displays from the dropdown menu. This should allow you to use all monitors as separate displays.
    4. Update Graphics Drivers: Ensure that your graphics drivers are up to date. Outdated drivers can cause issues with multiple monitor setups.
    5. Check Monitor Settings: Verify that each monitor is set to the correct input source. Sometimes monitors can be set to the wrong input, causing them to mirror each other.

    If these steps do not resolve the issue, you may want to consult the user manual for your docking station or reach out to the manufacturer's support for further assistance.
