How do I determine if I should use the ColorComp feature on my display?
Use the White Screen Background test pattern available in the Monitor Settings dialog available on the Tools menu to evaluate the screen uniformity. If there are any areas of the screen that appear non-uniform and present a problem with your color workflow and evaluation, try enabling the ColorComp control and adjust the slider control and see if the areas improve. Find the minimum setting that provides the best acceptable improvement. Each display will be different so there is no ideal setting for all displays.
