(optional) check my answer (optional)

Explanation:

When a monitor has no picture but is powered - on and the cable is connected, checking simple settings like brightness and contrast first is a logical and easy - to - do step. Returning to the manufacturer is too extreme without further investigation. Opening the computer and switching the video card slot or reloading the video card driver are more complex and should be done after basic checks.

Answer:

B. Check the brightness and contrast settings using the monitor’s controls.
