  1. Check the connections:
    First, analyze to see if the connections are secure.
    If the connection is loose, firmly connect them so that an uninterrupted signal can be received.

  2. Check the settings:
    Ensure that the extended display is the primary display.
    Check if the adapter is compatible with the external display.

  3. Check the cables:
    Make sure your cables are not damaged. Replace them if necessary.

  4. Check the drivers:
    Review if the driver is up-to-date.

  5. Check system updates:
    Verify you have the most recent system updates.
