15 ft Straight Through Serial Cable - DB9 M/F

When you troubleshoot issues with a VGA 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:

• Video cables

• Video source

• Video destination

To test your setup components, try the following:

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

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

• Test each cable individually.

• Use short cables when you are testing.

There are several issues that could be causing you to experience an issue with the color on your VGA display when you use a StarTech.com VGA cable. Issues with the color include an image that is a solid color or is missing colors (typically red, green, or blue).

To prevent issues, make sure that the following is true: 

• The cable is tightly screwed into each of the ports.

• The female connectors/ports are free of debris or anything that may prevent electrical conductivity.

• No pins are bent or missing in male VGA connectors/ports.
