A technician has set a laptop display to a resolution that was not supported and now cannot see the desktop. Which of the following diagnostic options would the technician choose to correct the issue?

The correct answer is A. VGA mode. VGA mode (also called 'Enable low-resolution video' in Windows boot options) forces the system to boot at a standard low resolution (typically 640x480 or 800x600) that virtually all monitors support.

Explanation

VGA mode (also called 'Enable low-resolution video' in Windows boot options) forces the system to boot at a standard low resolution (typically 640x480 or 800x600) that virtually all monitors support. This allows the technician to see the display and then correct the resolution settings. Driver rollback (B) would require access to Device Manager, which is inaccessible if you can't see the display. Restore from backup (C) is overly drastic for a simple resolution misconfiguration. Recovery console (D) is a command-line environment used for OS repair, not for changing display settings.
