Each step of this workflow has been optimized to display relevant information, and automatically configure common settings. Both Pre-Calibration and Post-Calibration measurement steps are included for comparing pre- and post-performance.

Note: For best results, the workflow steps should be performed in order, as many steps include automation designed to be performed in order

Step 1

  • From the Calman Menu in the top-left, choose Open Workflow Template and then LG AutoCal
  • On the introduction screen, choose the Display Type (OLED/LCD/Projector) and Colorspace Target (SDR/HDR/Dolby Vision)
    • This pre-configures the workflow for the desired targets.
    • At the end of the selected workflow, you will have the chance to proceed to another colorspace target

Step 2

Connect your Colorimeter and Pattern Generator to Calman. And, confirm your calibration targets, which have been pre-configured based on suggested values

  • Plug your meter into a USB port on the computer and press the Find Meter button on the left
    • When your meter is connected, select your display type from the dropdown (this will vary by meter)
      • OLED: White-OLED (OLED (White) LG, Panasonic, FSI 2018 for C6 Meter)
      • SuperUHD LCD - LCD LED Blue-Green (2018 LG SuperUHD LCD for C6 Meter)
  • Connect Pattern Source to your computer. If you're using the internal pattern generator, see this article for connection steps
    • Click the Find Source button then select your source
    • Select the pattern window size
      • OLED:  Window 10%
      • LCD: 100% full-screen (SDR)
  • Confirm your Calibration Targets
    • Colorspace
      • SDR: Rec.709/sRGB
      • HDR/Dolby Vision: Rec.2020

        • Day: Power 2.2
    • Whitepoint
      • D65

Step 3

In this step, you'll take readings of your display before the calibration. These will be used to compare your calibration results

  • To take Pre-Calibration Measurements click the Read Series [...] button to measure the display's grayscale and ColorChecker response
    • This will provide a point of reference to compare your calibration results

Step 4

Connect to, and prepare your LG TV for calibration

  • Connect to your LG TV
    • Click the Find LG TV Button
    • Pick the LCD or OLED Model you are calibrating in the drop down under Model.
    • Enter your TV's IP Address into the connection dialog box, and click Connect

  • When prompted, enter the 8 digit passcode displayed on the TV

 

  • Select Picture Mode to Calibrate.
  • Each Picture Mode is a separate memory slot for calibration data. Calibrations to one mode and colorspace do not affect the other picture modes.
  • Using the picture mode dropdown menu on the left, select which picture mode you would like to calibrate.
    • SDR Picture Modes:
      • Cinema
      • Expert 1
      • Expert 2
      • Game
      • Technicolor (2019/2018)
      • Filmmaker (2020)
    • HDR Picture Modes:
      • HDR Cinema
      • HDR Game
      • HDR Technicolor (2019/2018)
      • HDR Filmmaker (2020)
    • Dolby Vision Picture Modes:
      • Dolby Vision Cinema
      • Dolby Vision Cinema Home
      • Dolby Vision Game
  • After selecting your picture mode, click the Full DDC Reset button. This resets and prepares the picture mode for calibration.
  • Confirm Colorspace and Dynamic Range are set appropriately to match your target
    • SDR: BT.709, HDR UNCHECKED
    • HDR/Dolby Vision: BT.2020, HDR CHECKED

Step 5

  • Enable the calibration process by checking the checkbox. If it is already checked, proceed to the next workflow page.
  • You will see a Calibration Start notification on the TV if this step has completed successfully

Step 6

In this step, you will be able to adjust the Luminance of your display to match your desired target. Luminance is a subjective target. SDR reference luminance is 100cd/m2, but you may need to target higher to account for the ambient light in your environment.

Note: This step is not present in HDR and Dolby Vision

  • Click the Measure Luminance button to measure your TV's light output at 100% white and adjust the display’s peak white to the desired luminance.
    • Luminance is a subjective target. SDR reference luminance is 100nits, but you may need to target higher to account for the ambient light in your environment.
  • Adjust your TV's backlight/OLED light control so your TV is about 15% brighter than your final target to account for a reduction in luminance when calibrating the 1D LUT in the next step
  • Press Stop when luminance adjustment is complete

Step 7

Here Calman will adjust the Multipoint Greyscale of your display using a 1D LUT.

  • Press the AutoCal button and select the correct data points to auto-calibrate the Grayscale/Luminance response on your display.
    • SDR: There are several SDR Greyscale Point options. Choose the one that best fits your video levels. In most case 26pts SDR 16-255 is appropriate
    • HDR: 20pts HDR or 42pts HDR
  • Click OK to begin greyscale AutoCal

OLED Shadow Control

For the 2021 LG TVs we have a new control called shadow detail. It is intended to adjust on a per panel basis the amount of shadow detail that is visible. We worked with LG closely on this so they could enable users to adjust this near-black behavior for their specific panel instead of having a generic adjustment that is set by the firmware.
 

Step 8

On this page, Calman will calibrate the Color Management using a 3D LUT

  • Press the AutoCal button to open AutoCal dialog
    • All options are preconfigured
  • Click OK to begin colorspace AutoCal process

Step 9

Here you will be able to manually adjust your Brightness and Contrast to ensure the display is not clipping away any RGB values near white

Note: This step is not present in HDR and Dolby Vision

  • Adjust the display's Brightness and Contrast controls to set dynamic range (black to peak white).
  • In most cases, the default brightness and contrast values are appropriate for calibration
  • Click the Brightness button to display the brightness pattern then adjust brightness manually.
  • Click the Contrast button to display the contrast pattern then adjust contrast as high as possible without blending the brightest gray bars together and without shifting their color.
  • In the Datapoint levels drop-down, select Clipping with Peak White (90-109%), unless your pattern source does not generate patterns over 100% white, then select Clipping (90-100%).
  • Click the Read Series button and view the clipping detector graph chart to verify the Contrast adjustment.
  • If the RGB signals plateau at peak levels, reduce the Contrast slightly and retest.
  • Select the 100/235 pattern, click the Read Continuous button, and adjust the display’s peak white to the desired luminance from Step 6

Step 10

  • Uncheck the Enable Calibration checkbox
  • Proceed to the next page

Step 11

In this step, you'll take readings of your display after the calibration. These will be used to compare your calibration results

  • Measure the display with a combination of a grayscale and X-Rite/Pantone ColorChecker patterns. This provides an accurate assessment of the display following calibration and will be represented along with the pre-calibration readings on the next page
  • Click the Read Series [...] button to measure the display's grayscale and ColorChecker® response.
  • Click Next to review calibration.

Step 12

  • Pre (top) and Post (bottom) calibration information will show the calibration results. 
  • Click New Cal to return to the introduction page, where you can choose to calibrate a new picture mode and/or colorspace
  • Click Save Data to complete this calibration.
