220-802 Question #502: Real Exam Question with Answer & Explanation
The correct answer is D: Change the resolution in Safe Mode. Safe Mode loads Windows with a generic low-resolution VGA driver, allowing the technician to access Display Settings and revert the unsupported resolution without needing video output from the full graphics driver.
Question
A technician installs a new graphics card that supports high resolutions. The technician sets the resolution to the highest setting and then the monitor displays no video. The technician hits the enter key to exit and nothing happens. After a reboot, no video appears after the operating system loads. Which of the following would the technician perform NEXT?
Options
- AReseat the graphics card in a different slot
- BUpdate the graphics card driver
- CReinstall the operating system
- DChange the resolution in Safe Mode
Explanation
Safe Mode loads Windows with a generic low-resolution VGA driver, allowing the technician to access Display Settings and revert the unsupported resolution without needing video output from the full graphics driver.
Common mistakes.
- A. Reseating the card in a different slot does not change the resolution setting stored in the OS, so no video would still appear after the OS loads.
- B. Updating the graphics driver requires internet access and OS visibility, neither of which is available when the screen is blank after boot.
- C. Reinstalling the operating system is a destructive last resort and is entirely unnecessary when the problem is simply an incorrect display resolution setting.
