Explanation
When troubleshooting issues with multiple displays, you should start with the most likely causes, such as display settings and brightness configuration. Updating graphics drivers and restarting the system are also common steps to ensure proper hardware detection. Replacing cables should only be considered after verifying that the issue is not due to software or configuration errors.
- A. Correct.
Checking the display settings is a critical step to ensure the second monitor is recognized and configured correctly. The settings may be set to 'PC Screen Only,' which prevents the second monitor from displaying content.
- B. Correct.
Brightness settings can sometimes be set to the lowest level, making it appear as though the monitor is not working. Adjusting the brightness can help resolve this issue.
- C. Correct.
Outdated graphics drivers can cause problems with detecting or using multiple displays. Updating the driver ensures compatibility and proper functionality.

Replacing the cable is not the first step you should take. While a faulty cable could be the issue, it requires ruling out other standard troubleshooting steps first, such as checking settings and drivers.
