- Multiple Displays select Extend desktop to display
If the above method doesn't work, see the information below:

- Verify the other display is powered on.
- Try reseating the video cable on both ends: where it connects to on the display and on the computer.
- Try reopening the graphics properties window.
- Try rebooting the computer.
- If you are using a laptop computer and it is running on a battery, try connecting your laptop to an external power source. On some laptops, the external display device connector is not enabled when the laptop is running on battery.
