Most, however, show some level of banding. By matching your calibration gamma value to your monitor, you can significantly reduce banding. This is a good thing for digital image editing, as it allows you to distinguish image flaws from calibration artifacts. Notes: For best results, view the image without passing it through your monitor profile.

When you adjust the monitor, make sure lighting conditions in the room are what they usually are when you are working. If it’s off, it can have a dramatic effect on the image you see. For example, setting black level too low may obscure low brightness details into the background. Setting black level too high will display black information as gray, killing any hope for depth and realism in the image (see below). Fire it up, go to the black level test, and Author: Matt Whitlock.
