Final Words

If you are having a DisplayPort not working issue on your Windows 11 device, we have some simple but effective troubleshooting methods to help you out. Here are some tips to try if you are struggling:

  1. Check if your DisplayPort is working properly by checking the output of the Device Manager. If it says that your DisplayPort is connected and working, then there’s no need to troubleshoot further. However, if your DisplayPort isn’t working at all or has a very low signal strength, then it might be worth checking whether or not you can fix the issue by connecting another device to your computer using DisplayPort cables.
  2. Try connecting another device to your computer usingDisplayPort cables. This might help fix the problem if it’s not caused by a problem with yourDisplayPort itself. If this doesn’t work, then you might need to take apart your device and check for any issues with its connectors or circuitry.
  3. Resetting your computer may help fix the issue if it’s not caused by a problem with its hardware or software. Resetting everything (including the BIOS) can sometimes solve problems that don’t seem related to hardware or software issues.
