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

There are some quick tests that you can complete to rule out potential issues. You can test to make sure that the following components are working correctly and are not the source of the issue: Video and Ethernet cables Mouse and keyboard Video source (such as a DVR or computer) Video destination (such as a monitor or projector) Note: When you test setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI extender, you should use an HDMI source when you test the components. To test your setup components, try the following: Use a different cable, mouse, keyboard, 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. Use the cable, mouse, keyboard, video extender, video source, and video destination in another setup to see if the problem is with the components or the setup. When you test your cables, it is recommended that you do the following: Test each cable individually. Use short cables when you are testing. When you test the video source and video destination, it is recommended that you do the following: Test to make sure that the video source and video destination work together without using the KVM extender. Test to make sure that the video source and video destination work together at the resolution that you want to use. Note: In order for your setup to work properly, the video source, extender, and destination all need to support the resolution that you are using.
