Second Monitor Not Working? What to Check Before Calling

If your second screen isn’t displaying anything, it’s often a connection or settings issue. Here are some quick fixes you can try before raising a support ticket.

1. Check the Cable Connections

• Confirm both ends of the HDMI, DisplayPort, or VGA cable are plugged in

• Try reseating or swapping the cable

• Make sure the monitor is powered on

2. Use Windows Display Settings

• Right-click the desktop > Display settings

• Click Detect to search for connected displays

• Scroll down to Multiple displays and choose Extend or Duplicate as needed

3. Try the Monitor on Another PC

• If it works elsewhere, the monitor is fine and the issue is likely with the original PC or cable

4. Test a Different Port

• Many PCs have multiple output ports (e.g. HDMI and DisplayPort)

• Switch to a different port and restart your machine

• If using a docking station, try bypassing it and connecting directly

5. Restart with Only the Second Monitor Connected

• Shut down the PC

• Unplug the primary screen (if possible)

• Boot with just the second monitor connected to force detection
