You are working as a technician at Certkiller .com. A user requests some assistance with her
computer. It seems that her display is limited to a 16 color mode. Which of the following
alternatives could be the cause of this problem?

A.
There is an incompatible driver installed.

B.
The computer is running in dual monitor mode.

C.
The interrupt request for the video adapter in the BIOS is disabled.

D.
The monitor is not compatible with the video adapter in the computer.

Explanation:
An incompatible driver will cause the system to fail-over to a generic display driver with minimal
functionality just to ensure that a technician can still access the operating system and replace the
faulty display driver.
