SDR Calibration

Step 1

  • From the Calman Menu in the top-left, choose Open Workflow Template -> Display Specific and then AutoCal – Philips
  • On the introduction screen, click SDR Calibration to proceed to the hardware connect page
  • 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: OLED TV (2021) for Portrait Displays C6 Meters
  • Connect Pattern Source to your computer.
    • Click the Find Source button then select your source
    • Select the pattern window size
      • OLED: Window 10%
      • LCD: APL18 for SDR
  • Connect to your Philips TV
    1. Press the Menu button on the Remote
    2. Select Frequent Settings > All Settings > Picture > Al Picture
      • For LCD TV 92×6/90×6, select Frequent Settings > All Settings > Picture > Picture
    3. Select Calman (if locked press 225626)
    4. Press the Green button on the remote to initiate calibration
      connertion
    5. The TV will show the IP address once in connection mode, enter
      that IP address in the field and press the ‘Find Philips TV‘ button
    6. Choose Make: Philips; Model: Philips OLED 9×6/8×6/7×6 LCD 9xx6
    7. Enter your TV’s IP Address into the connection dialog box, and click Connect
  • Select the Grayscale calibration method to use. Gains only produces
    excellent results for a Power Function 2.2 curve, for other Gamma
    formulas/targets a 1D LUT may return better results.
  • Select the display type
    • OLED or LCD

Step 2

Confirm your calibration targets and prepare TV
  • For best results, please configure your Calman settings to match the configuration recommended below.
    • Rec709
    • D65
    • Gamma
      • Power 2.2 gamma formula
  • To prevent a Philips 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.
    • Under Calman Settings > Application Measurement Options set the following Full Field Pattern Insertion options:
      • Frequency: 45
      • Duration: 5
      • Pattern Level: 25
  • AutoCal dE Formula
    • dE ITP
      • Increases accuracy, but calibration time may be extended
    • dE ICtCp 240
      • Improved speed, with a small tradeoff in accuracy

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
  • Note: The TV’s Calman mode setting before the pre-calibration measurement process may use default color temperature (e.g. Custom) which is not the D65. You may change TV color temperature to Warm mode via TV settings before the measurement starts.

Step 4

  • Click the Reset button. This resets and prepares the picture mode for calibration.
  • Click Next after the DDC reset is complete

Step 5

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
  • Click the AutoCal button to calibrate the 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 Next when luminance adjustment is complete

Step 6

Here Calman will adjust the Multipoint Greyscale of your display using a 1D LUT
  • Press the AutoCal button and select the correct data points in the AutoCal Dialog to auto-calibrate the Grayscale/Luminance response on your display.
    • Choose 17 Point – Limited Range
  • Click OK to begin greyscale AutoCal

Step 7

On this page, Calman will calibrate the Color Management System
  • Press the AutoCal button to open AutoCal dialog
    • Defaults have been chosen to provide best results
  • Click OK to begin colorspace AutoCal process
  • When AutoCal is complete, press the Next button to proceed

Step 8

It’s common to lose some overall luminance after the 1D LUT calibration. Use this step to adjust back to your luminance target if it has changed
  • Click the Autocal 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.
  • Press Next when luminance adjustment is complete

Step 9

In this step, you’ll take readings of your display after the calibration.
  • Click the Read Series […] button to measure the display’s grayscale and ColorChecker® response.
  • Click Next.

SDR Calibration is complete.

Note: If the SDR calibration is using Gamma of 2.2, you may copy and apply the SDR mode calibrated color temperature and 1D greyscale LUT settings to HDR Calman mode to skip HDR calibration process. To do so, please use the TV remote control to press key sequence 225626, then follow the TV’s pop-up on-screen display message instruction. You may lock Calman mode TV settings to prevent unintentional change. Once locked, the Calman settings will not be changed if the TV performing a software update, factory reset, or reinstallation of the TV. You may use the same key sequence to unlock.
