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

When you troubleshoot issues with a DVI 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:

  • DVI cable

  • Video source

  • Video destination

To test your setup components, try the following:

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

  • Use a different DVI 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 video cables, video source, and video destination, it is recommended that you do the following:

  • Make sure that you are using the correct type of DVI cable. For more information about DVI cables, see the following FAQ: http://www.startech.com/faq/video_signal_converters_dvi_interface.

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

  • Test your setup components using a lower resolution or a lower refresh rate, for example, 1024 x 768.

Note: Single Link DVI cables are only capable of resolutions up to 1920 x 1080. In order to obtain a resolution of 2560 x 1600, you will need to use a Dual Link DVI cable. For more information, see the FAQ link listed above.
