Calibration

Calibration is the process of measuring what a display actually puts out — its brightness, white point and colour response — and correcting it toward a known standard such as Rec.709, D65 white and a defined gamma. You read the screen with a probe, compare the measurement against the target, and either adjust the monitor’s own controls or write a correction (a LUT or profile) that nudges it into line. Calibration can only work within the panel’s real limits: it can make a display accurate to what it can already do, but it cannot give a consumer screen contrast, brightness or gamut it never had. The result is a calibrated display you can trust — or at least an honest read on how far yours falls short.
