Q: What are some basic monitor troubleshooting steps?

A: Problems with video are not always caused by the monitor. Some causes of video problems include video cable issues, video card issues, a corrupt video driver, or an incorrect display setting.

Following is a list of basic steps to help determine if the monitor is causing the video problem you are experiencing. After each step, determine if the video problem is still apparent.

• Turn off the computer and the monitor. Reseat (disconnect and then reconnect) the monitor cable on the computer and the monitor, if it is not permanently attached to the monitor. Check for bent pins on the connectors. Turn on the monitor, and then turn on the computer.
• Plug the monitor and computer power cables directly into a known good outlet.
• Connect the monitor to a different computer.
• Connect another monitor to the current computer.
• Refer to the self-test section of the specific monitor. When running the self-test, follow the instructions listed for that monitor.
• Test for the video problem in the BIOS or Windows® Safe mode.
• Confirm that the brightness, contrast, and all other monitor controls are set for optimum viewing.

If these basic troubleshooting steps do not resolve or clarify the source of the issue, refer to your model monitor's Users Guide and product information for specific support documents, driver installations and frequently asked questions (FAQs). Also, remember that some causes of video problems may originate with the video card, video driver, or an incorrect display setting. Refer to your model video card's product information for specific support documents, driver installations and frequently asked questions (FAQs).
