Detailed information about all of the colour profiles installed on your Mac (and used by connected cameras, printers and displays) is provided in ColorSync Utility (in the Applications > Utilities folder). See the ColorSync Utility User Guide. You can also create your own custom colour profile by calibrating your display.

Refresh rate				Adjust how frequently your screen is redrawn. If the rate is too low, your screen may appear to flicker. If the rate is too high, the screen may be black because it doesn’t support that rate. Check the documentation that came with your display for the best rate. If you have a supported display, you can set your display to dynamically adjust its refresh rate, using Adaptive Sync. This option only appears if an external display that supports changing the refresh rate is connected to your Mac.
