B. Make sure that the power is switched off and the power cord is plugged out

C. Make sure that the ESD is grounded properly

D. Connect the Monitor as well as the wrist strap to the ground.

Never wear a wrist strap when working on monitors. Monitors contain very high voltages, sometimes fatal to human, even when the power is turned off. If you are wearing wrist strap, the human body work as a conduit to discharge the electric charge.
