  • D65
  • Gamma
    • For a reference viewing mode (Night Mode)
      • OLED models should target Power 2.4 gamma formula
      • Super UHD LCD models should target ITU BT.1886
    • For a bright room viewing mode (Day Mode), both OLED and LCD models should target Power 2.2 gamma formula.
  • Hardware Options
    • Pattern Size:
      • OLED: Window 10
      • LCD: Constant APL 10

Step 3

For best results, please configure your Calman settings to match the configuration recommended below.

• To prevent an LG OLED display from entering its auto-dimming mode during extended measurements, the Calman Pattern Insertion feature periodically inserts a different test pattern during extended test pattern measurements, to reset the display’s auto-dimming timer. This is not required on LCD and NanoCell models.
  • Press Set SDR Default to configure the following settings
    • Pattern Insertion
      • Frequency: 45
      • Duration: 5

HDR Calibration is complete.

This new Dolby Vision calibration process is quite different than any previous calibration process for TVs.

First, some background information. Current HDR-compatible televisions are still based on 2.2 gamma at the panel level. The HDR EOTF (ST 2084 or HLG) is then mapped onto the native panel response of 2.2 gamma.

Working with LG and Dolby, Calman sends special Dolby Vision “Relative Mode” metadata to put the TV’s Dolby Vision engine into pass-through mode. You then calibrate the grayscale 1D LUT to 2.2 gamma and D65 white point using AutoCal.

After you calibrate the grayscale to 2.2 gamma and D65, you will use Calman to create a custom Dolby Vision config file, by taking White, Black, Red, Green, and Blue measurements.

To verify the results of your calibration, you will set your pattern generator’s Dolby Vision metadata to “Absolute Mode.” Then, verify the calibration results against D65, P3 Primaries, and ST 2084 EOTF.

Step 1

• From the Calman Menu in the top-left, choose Open Workflow Template -> Display Specific and then AutoCal – LG
