Calibration
Multi-Point Grayscale Adjust
August 3, 2020To calibrate its grayscale tracking, a display may provide only two-point white balance controls, only multipoint white balance controls, or it may provide both. If both types of controls are provided, it is generally best to adjust the two-point controls first, and then adjust the multipoint controls, if necessary….
Luminance Adjust
August 3, 2020After a display’s Brightness and Contrast controls have been accurately adjusted to maximize the display’s dynamic range, the display’s luminance at 100% stimulus (peak white) should be adjusted. Many displays provide a means of setting the overall display luminance, independent of the Contrast control….
LG TV Custom Tone Mapping
January 11, 2023Calman 2019 includes support for the LG (2019) Dynamic Tone Mapping. This feature is used to modify the way the TV’s internal processing handles HDR content that exceeds the panels peak luminance. This is referred to as a Roll-Off point. …

August 3, 2020A color model is a system of describing colors as three or four color values or components (i.e. RGB, XYZ, and CMYK). A color space is a specific implementation of a color model that defines a particular set of colors. There are many defined and device-specific color spaces that use each color model….
How to Retarget a 3D LUT
August 3, 2020Create a corrective 3D LUT from a previously saved LUT file with Calman. The LUT Retargeting feature in Calman 5.4 and later allows users to create a 3D LUT for a new colorspace standard from a previously created LUT file. This feature is perfect for those who need multiple calibration profiles per monitor, for instance, if you are working in both Rec.709 and DCI/P3 color standards….

August 3, 2020The ultimate goal of display grayscale calibration is to perfectly balance each primary color to produce the target white balance color (usually D65) at every grayscale level from black to peak white. The practical goal, however, is to balance the colors to within an acceptable error at each grayscale level, as indicated by the Delta E chart. This insures that video content viewed on the display visually matches the white reference color (D65) that was used when studios and broadcast stations mastered the video content….
Gamma Basics
August 3, 2020Gamma is the exponent that relates a display’s input signal level to the amount of light that it produces at each signal level….

Tags: 3DLUTContrast Adjust
July 27, 2023A crucial step in calibrating a display is to accurately adjust the display’s peak white level (Contrast control), which is critical to maximizing its dynamic range (luminance range from black to white). A display’s Contrast control adjusts the amplitude of the video signal and is sometimes called picture level because it establishes how much difference (contrast) there is between the black and the white picture levels. This adjustment establishes the highest Contrast setting that produces an accurate picture, without compressing the red, green, or blue peak video levels….
