Both screens will show the same image, acting as a single, mirrored display. This is useful for presentations where you want the audience to see what you are doing on your laptop in real-time, or for sharing content on a larger screen with others in a small group.
Extending the display, on the other hand, transforms the external monitor into an extension of your laptop’s desktop. It effectively creates a larger workspace by allowing you to spread windows and applications across both screens. This is ideal for multitasking, as you can have different applications open on each screen simultaneously, improving productivity and workflow. The choice between mirroring and extending depends entirely on your specific needs and use case.
How can I troubleshoot flickering or distorted images on the external monitor?
Flickering or distorted images on the external monitor can be frustrating, but several troubleshooting steps can help identify and resolve the issue. Start by checking the cable connection and ensuring it’s securely plugged into both the laptop and the monitor. A loose or damaged cable can cause signal interference. Try using a different cable to rule out a faulty connection as the source of the problem.
Next, verify the monitor’s refresh rate and resolution settings. Ensure they are compatible with your laptop’s capabilities and the monitor’s specifications. A mismatch between the settings and the hardware can lead to flickering or distortion. Update your laptop’s graphics drivers to the latest version, as outdated drivers are a common cause of display issues. If the problem persists, try resetting the monitor to its factory default settings. In rare cases, the monitor itself might be faulty, requiring repair or replacement.
