CalMAN 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.

With the advent of the 3D displays, we have all been left wondering... What is relevant in a 3D display? How do active shutter glasses affect viewing? What should we look for in a 3D display? What procedure should we use? This is designed to answer all of these questions.
To 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.
A crucial step in calibrating a display is to accurately adjust the display's black level (Brightness control), which is critical to maximizing its dynamic range (luminance range from black to white) in the intended viewing environment. A display’s Brightness control adjusts the display's black level. It sets the minimum amount of light the display produces at black signal levels.

A video display color decoder converts a YCbCr digital video signal back into its original RGB format. Modern video displays with HDMI digital inputs process video signals in YCbCr format. However, at the end of a display’s video processing path, the YCbCr component video signal needs to be converted back to an RGB signal, to be usable by the display’s imaging control device (e.g. electron gun and phosphors in a CRT, imaging chip(s) and filters in an LCD). This conversion of the processed YCbCr component video signal into an RGB signal is done by the display’s color decoder.
A 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.
A display’s color temperature specifies the background color of white and neutral grays in the display’s picture.
A 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.
Gamma is the exponent that relates a display’s input signal level to the amount of light that it produces at each signal level.
The 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.
After 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.
To 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.
As the first step in display calibration, you should investigate the effects of the various picture viewing modes provided by the display. Each of the provided viewing mode selections contains a unique combination of picture and operational characteristics. You want to select one or more of the available picture modes as a starting point(s) for the calibration. Depending upon the display model, some modes may be less suitable or totally unsuitable for calibration.
The Sharpness feature in modern displays was originally designed to visually enhance low-resolution source content by enhancing the brightness transitions at the edges of objects in a scene. This edge enhancement creates a thin halo effect at all image edges.
Video content is generally displayed in either Full (or PC) range, or Video (or SMPTE, legal). This determines the greyscale range of the displayed content. This article will illustrate the differences.
