The external displays stopped working on my Surface Pro 7. The Surface can no longer detect external displays.

    Force detection: Press Win + P and choose Extend or Duplicate. Then go to Settings > System > Display, scroll to Multiple displays, and click Detect (if it’s not showing, click the “Detect” or “Connect to a wireless display” options).

    Check the cable and adapter: This is the most common cause. Surface Pros have only USB-C/Surface Connect, so you’re probably using an adapter. Cheap USB-C to HDMI/VGA adapters often fail. Try a different cable or adapter, and make sure it’s fully seated.

    Check the monitor’s input source: Use the monitor’s menu button to manually select HDMI, VGA, or USB-C instead of “Auto”.

    Power cycle everything: Unplug the monitor’s power and video cable for 30 seconds, plug the monitor in and turn it on first, then connect it to the Surface. A full Restart (not Shut down) of the Surface helps too.

    Try another port or device: Test the monitor with another laptop. If it works there, the problem is on the Surface or adapter side. If it doesn’t, the monitor or its cable is the issue.

    Update or reinstall the graphics driver: Run Windows Update, including Optional updates. Then in Device Manager > Display adapters, right-click your graphics adapter and choose Uninstall device, then restart. Windows will reinstall it.

    Check the refresh rate and resolution: An older 15" Acer may only support a lower resolution. If the signal is out of range, it can show as “not detected”. Try a different cable type if possible.

    If your Surface Pro 7 is having trouble detecting external displays, you can follow these troubleshooting steps:

    1. Check Connections: Ensure that all cables are properly connected to both your Surface Pro 7 and the external displays.
    2. Use Keyboard Shortcuts: Press Win + P to open the Project menu, which allows you to switch between different display modes (such as Duplicate or Extend). This can help in recognizing the external displays.
    3. Display Settings: Navigate to Settings > System > Display and click on the Detect button to prompt Windows to search for external displays.
    4. Power Options: If your Lid close action is set to "Do nothing," consider changing it to another option, as this setting may impact the detection of external displays.
    5. Update Drivers: Make sure your graphics drivers are up to date. You can check for updates in Device Manager or via Windows Update.
    6. Restart the Device: A simple restart of your Surface Pro 7 can sometimes resolve detection issues.
    7. Firmware Update: Check if your Surface Pro 7 has the latest firmware updates. Go to Settings > Update & Security > Windows Update to see if any updates are available.
    8. Try Different Ports or Cables: If possible, test with a different USB-C port or a different cable to connect the external display.

    If these steps do not resolve the issue, consider reaching out to Microsoft support for further assistance.
