Step 2 Calibration Targets
Confirm your calibration targets and prepare the TV. Settings will be automatically set as part of the workflow.
- For best SDR calibration, configure Calman settings to match the configuration recommendation provided in the workflow.
- Whitepoint: D65
- Corlorspace: Rec709
- EOFT: BT.1886
- AutoCal dE Formula
- dE ITP
- Increases accuracy, but calibration time may be extended
- dE ICtCp 240

Step 3 Application Settings
Select Set calibration mode defaults for SDR
To prevent an OLED display from entering auto-dimming mode during extended measurements, the Calman Pattern Insertion feature periodically inserts a different test pattern during measurements, to reset the display’s auto-dimming timer. This can be disabled for LCD TVs.
Press the Set SDR Defaults to configure pattern insertion to the following parameters
- Pattern Insertion
- Frequency: 5
- Duration: 5
- Pattern Level: 25
- Pattern Stabilization
- Patches: 1
- Duration: 1
- Level: 10
Step 4 Pre-Cal Measure
In this step, takes readings of the display before the calibration and are used to compare the calibration results.
-
Select Measure button to take Pre-Calibration Measurements of the display’s grayscale and ColorChecker response
- This will provide a point of reference to compare your calibration results
Once Pre-Calibration Capture is complete, click Next
Step 5 Display Reset
Display Reset is used to update the Display Controls for the selected mode.
On the Display Reset page:
-
On the Display Reset page:
- Choose the picture mode you wish to calibrate
- The following modes are available for calibration:
- Theater Day
- Theater Night
- Game
- FILMMAKER MODE
- The following modes are available for calibration:
- Click the Reset button. This resets and prepares the picture mode for calibration
- Click Next after the DDC reset is complete
- Choose the picture mode you wish to calibrate
Step 6 Luminance
In this step, adjust the Luminance of the display to match the 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 the environment
- Click the Measure 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.
- Use the Blacklight slider to adjust for the desired results.
- Press Stop when luminance adjustment is complete
Step 7 White Balance
For this step, Calman will adjust the display’s White Balance
- Click the AutoCal button to perform the 2pt greyscale AutoCal
Step 8 Grayscale Multipoint
This step, Calman will adjust the Grayscale Multipoint of the display
- Press the AutoCal button and verify that the SDR point set is selected
- Click OK to begin greyscale AutoCal
Step 9 3D LUT Calibration
This step, Calman will calibrate the Color Management using a 3D LUT
- Press the AutoCal button to open the AutoCal dialog
- Calman has multiple methods for creating a 3D LUT. For information about these LUTs see 3D LUT ARTICLE
- Suggested using the Hybrid_5 for the best results
- Choose the video range matching the target and pattern generator settings
- Click OK to begin the colorspace AutoCal process
When AutoCal is complete, press the Next button to proceed
Step 10 Verify Luminance
It’s common to lose some overall luminance after the 1D LUT calibration. Use step this to adjust back to your luminance target if it has changed
- Click the Measure button to measure your TV’s light output at 100% white and adjust the display’s peak white to the desired luminance
- Press Stop Measuring when luminance adjustment is complete
Step 11 Post Calibration
Post-calibration readings to document the post-calibration condition of the display.
