    Hi,

    What is the laptop model?

    When you connect the HDMI cable to the laptop and go to Settings > System > Display, do you see two screens listed?

    If so, try "Extend" mode and see if the screen appears.

    If a second screen doesn't appear, try using a different HDMI cable.

    Thanks.

    Try this in order:

    1. Press Windows logo key + P and select Duplicate. If the TV is detected, this mirrors the laptop screen to the TV.
    2. Disconnect all accessories from the laptop, including docks, dongles, and adapters, then connect only the HDMI cable to rule out conflicts.
    3. Make sure the HDMI cable is firmly connected on both the laptop and TV.
    4. On the TV, switch the input source to the correct HDMI input.
    5. Try a different HDMI cable. If the new cable works, the original cable is faulty.
    6. Try the TV with a different system. This helps determine whether the issue is with the TV or the laptop.
    7. If the laptop has more than one video output port, try a different video output port.
    8. Reset the graphics driver by pressing Windows logo key + Ctrl + Shift + B.
    9. Restart the laptop: Start > Power > Restart.
    10. If the problem started after an update, roll back the display driver:
      • Search for Device Manager
      • Open Display adapters
      • Right-click the display adapter > Properties > Driver tab > Roll Back Driver
    11. If rollback is not available, reinstall the display driver:
      • Open Device Manager
      • Expand Display adapters
      • Right-click the display adapter > Uninstall device
      • Select Attempt to remove the driver for this device > Uninstall
      • Restart if prompted
      • Open Device Manager again
      • Right-click the display adapter > Update driver
      • Select Search automatically for updated driver software
    12. Make sure Windows is up to date in Settings > Windows Update.

    If one external display still does not work after these steps, file a report in Feedback Hub with the exact steps and results.
