The monitor calibration is guaranteed; if this is not achieved to the best a specific monitor can offer, it will be recalibrated until the result is reached at no additional cost.
At first a monitor is calibrated using the built-in controls, if the result is sufficient then the job is done. Alternatively, if exceptional accuracy is desired, a 3D Corrective LUT box can be added and will be calibrated to compensate for specific short-comings in the monitor.
