You update the video card driver on a computer that runs Windows 8.1.
You can no longer configure the display settings to extend the display to a projector.
You need to restore the display options as quickly as possible and retain all user data.
What should you do?
A.
Run the DisplaySwitch /extend command.
B.
Roll back the video card driver to the previous version.
C.
Start the computer from the Windows 8 installation media and perform a system image recovery.
D.
Run the sfc /scannow command.
Explanation:
Rolling back the driver is the simplest and fastest solution.
Further Information:
The DisplaySwitch /extend command might not work is the driver is broken.
The sfc /scannow command checks system files for consistency.
And a system image recovery will affect the user data.
