Your Computer monitor is not displaying a picture. What would you do to Troubleshoot the problem?

A. Verify the display settings
B. Plug the power cable into the computer.
C. Look at the monitor for an indicator light.
D. See if there is something plugged into the USB drive.

It would be B, monitor cables use HDMI or VGA, not USB's. USB'S would have nothing to do with your monitor screen. 
Plug the power cable into the computer
