Below are some boxes, one should be absolute black. Nothing on your monitor should be darker than the black box.

This is a 10 section step wedge to allow you to check that you have a full chromatic scale available on your monitor. You should be able and see the 10 separate tones going from an all white to a total black.

One of these numbered boxes is about the same shade as the surrounding.

TV monitors are calibrated for 2.2 Gamma.
