Every Odyssey 7Q+ and Apollo OLED monitor ships properly color calibrated. This is an extremely accurate color calibration. Note that three separate, precise color calibrations are built-in, one for overall screen brightness setting of “Low”, one for “Medium” and one for “High”.
With this in mind if you would like to modify the factory calibration, to match your current “Standard”, you may do so. It is relatively common for various organizations to have a specific monitor that they use as their “Reference” and adjust all of their other monitors to this one monitor.
No special software or hardware is required, if you wish to make color adjustments “By Eye”. You may also use certain external color calibration systems.
