-If you have a touch screen display, try disabling the touch screen driver in Device Manager and then enabling it again.

-Check your computer’s Display settings to make sure your Dell display is set as the primary monitor.

-Try connecting your Dell display to a different USB port or using a different VGA cable if you’re using an external monitor.

By following these troubleshooting steps, you should be able to resolve any Dell display detection issues you’re experiencing.

Checking and Restarting Dell Docking Station and Cable Connections

To troubleshoot a Dell display not detected issue, checking and restarting the docking station and cable connections is a good first step.

To do this, follow these steps:
1. Disconnect and reconnect the Dell Docking Station to your computer’s USB port (make sure it’s securely plugged in).
2. If you’re using a DisplayPort cable, try a VGA cable instead, or vice versa.
3. Check that the cable you’re using is securely plugged into the docking station and monitor.
4. Restart your computer and the docking station.

If these steps don’t work, try updating the firmware on your Dell Dock (if applicable), and make sure your external monitor is turned on and set to the correct input.

If you’re using Ubuntu or a Dell XPS or Inspiron N5110, there may be additional steps you can try. But for most users, checking and restarting the docking station and cable connections should fix the issue.
