Fix: DisplayPort not working
DisplayPort problems are usually caused by a loose cable, monitor input source, graphics driver, high refresh rate issue, or adapter direction mistake.
Quick answer
Set the monitor input to DisplayPort, unplug and reconnect the cable, restart the computer, then try a different DisplayPort cable or lower refresh rate.
Important warning
DisplayPort cables can be sensitive to poor connections. Make sure the cable clicks or seats fully if it has a latch.
Try this
- 1 Set the monitor input to DisplayPort.
- 2 Unplug and reconnect the DisplayPort cable at both ends.
- 3 Turn the monitor off and unplug it from power for 30 seconds.
- 4 Restart the computer.
- 5 Try another DisplayPort cable.
- 6 Update graphics drivers.
- 7 Lower the refresh rate if the screen flickers or goes black.
Common causes
Monitor is on the wrong input.
DisplayPort cable is loose.
Monitor needs a power reset.
Graphics driver issue.
Refresh rate or resolution is too high.
Adapter is the wrong direction.
What to check next
- Check monitor input source.
- Check whether the cable is fully inserted.

- Check graphics driver updates.
- Check whether lowering refresh rate fixes it.
