Correct answers: A, C, D
Explanation
To resolve display and multiple monitor issues, it is essential to verify that the external monitor is detected, set the appropriate display mode (e.g., 'Extend'), and configure the resolution settings to the monitor’s recommended values. These steps directly address the user's concerns about incorrect resolution and lack of desktop extension.
- A. Correct.
Accessing display settings to verify that the external monitor is detected is a critical first step in troubleshooting display issues. If the monitor is not detected, further steps cannot be performed.
- B. Incorrect.
Adjusting the laptop's brightness settings does not directly affect the resolution or functionality of the external monitor. Brightness settings are not relevant in this scenario.
- C. Correct.
Changing the display mode to 'Extend' allows the external monitor to act as an additional screen rather than mirroring the laptop display or replacing it entirely. This matches the user's request to extend the desktop.
- D. Correct.
Resolution settings determine the clarity and size of the content displayed on the monitor. Ensuring the external monitor is set to its recommended resolution is necessary to fix the incorrect display resolution issue.
- E. Incorrect.
Restarting the laptop is not typically necessary unless there is a hardware detection issue. Since the external monitor is already connected, other troubleshooting steps should be prioritized.
