Using only one external monitor

If you’re not seeing what you expect on the external monitor, start with basic hardware troubleshooting:

  • Disconnect all accessories from your PC. Connected docks, dongles, adapters and other hardware can cause conflicts.

  • Try changing the cable connecting the external monitor. If the new one works, you know the previous cable was faulty.

  • Try using the external monitor with a different system. This can help to isolate whether the issue is with the monitor or the primary system

  • If your system has more than one video output port, try plugging your external monitor into one of the other video output ports. Typical ports are HDMI, VGA, DVI, and DisplayPort.

  • If your system has more than one display adapter, also called a graphics card, you can try switching your system’s default display adapter. For example, on some systems, you can right click your desktop and select the software associated with your additional display adapter. Steps to change the default display adapter vary by device, so contact the manufacturer for more information.

  • Docking station – To find out if there are docking stations available for your PC, contact the manufacturer of your PC.

  • USB adapter – If you have a USB-C port, you may be able to use a USB adapter to give your device an additional video output port.
