Everything is hooked up but nothing is working. What should I do?

When you troubleshoot issues with a DisplayPort cable, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • DisplayPort cable

  • Video source

  • Video destination

To test your setup components, try the following:

  • Use the DisplayPort cable, video source, and video destination in another setup to see if the problem is with the components or the setup.

  • Use a different DisplayPort cable, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test the DisplayPort cable, video source, and video destination it is recommended that you do the following:

  • Verify that the source resolution matches the capabilities of the video source destination. For example, if the destination is only capable of 1920 x 1080, then the source cannot output 2560 x 1600, as that exceeds the capabilities of the video source destination.

  • Test at a lower resolution or a lower refresh rate, for example, 1024 x 768.

  • If you are using 4K resolutions, test with a shorter cable.

If you are experiencing issues with the audio over DisplayPort, make sure that the following is true:

  • The source is set up to output audio over DisplayPort.

  • The destination is compatible with the source's audio format.

  • The destination volume has been raised.
