Calibrating BenQ monitors with Calman

December 18, 2025

The BenQ Monitor Calibration workflow in Calman provides automated calibration for supported BenQ models. Depending on the monitor’s capabilities, Calman can load a full 3D LUT directly into the display or apply a 1D LUT paired with a color correction matrix. This workflow guides you through configuring your targets and performing accurate calibrations using the monitor’s internal processing.

Calman Required Version

  • Calman (Ultimate or Studio) Version 5.16.7 or later

Hardware Requirements

Calman Supported Models

  • Matrix-Only Models
    • BenQ PV270
    • BenQ SW270C
    • BenQ SW271C
    • BenQ SW321C
  • 3D LUT or Matrix Models
    • BenQ SW272U
    • BenQ SW272Q
    • BenQ SW242Q

Step 1

  • From the Calman Menu in the top-left, choose Open Workflow Template -> Calman Ready and then BenQ.

  • On the introduction screen, select your calibration mode (SDR or HDR) from the dropdown and click Next to proceed to Hardware Setup

Step 2

  • 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
  • Connect Pattern Source to your computer.
    • Click the Find Source button, then select your source
      • Note:
        • For HDR calibration, your source should NOT send any HDR metadata.
        • PG and display should both be set to Full Range.
        • Internal Pattern Generator not supported for HDR calibration
    • Select the pattern window size and delay
      • Window 10% with 1-second delay
  • Click Next to proceed

Step 3

  • Confirm/configure your calibration targets. These will be automatically set to common defaults by the options from Step 1
SDR HDR
  • Preset Targets:
    • Colorspace:  rec.709 
    • Gamma Formula:  ITU BT.1886
    • Whitepoint:  D65
  • Preset Targets:
    • Colorspace:  rec.2020
    • Pre/Post-Cal Gamma Formula:  ST 2084 (PQ)
      • Calibration will be performed in Power 2.2
    • Whitepoint:  D65

(Optional) Current State Measurements

  • This workflow page is intended to document the monitor’s current operational state before establishing any DDC connection or selecting a calibration mode.
  • This step can be skipped if documenting the current state is not needed. Another set of Pre-Calibration measurements will be taken in later steps.

  • To take Current State Measurements, click the Measure button to measure the display’s rayscale and color response.
  • Click Next to proceed

Step 4

  • Connect your BenQ Monitor
    • Connect the monitor to the computer using a USB-C cable for communication.
    • Click Find Display 
    • On the Find Display dialog, choose the option containing your BenQ model and click Connect.
      •  

Pre-Calibration Measurements

  • This workflow page is intended to document the target picture mode prior to calibration.

  • To take Pre-Calibration Measurements, click the Measure button to measure the display’s rayscale and color response.
    • This will provide a point of reference to compare the calibration results
  • Click Next to proceed

Step 5

  • Here, the target picture mode can be selected, and the display will be reset to prepare for calibration.

  • Select the display mode and method you wish to calibrate, and click Reset to prepare the display for calibration

Notes:

  • Each mode can only be calibrated for either SDR or HDR. Use different modes for each to prevent calibration loss
  • Each mode can only store a 3D LUT OR a Matrix calibration, not both.
  • Calibration Slots marked with 3D LUT:
    • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3D LUT for color gamut correction
  • Calibration Slots marked with Matrix
    • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3×3 matrix for color gamut correction
  • NOTE: The Reset process may take up to 15 minutes

 

  • Click Next to proceed

SDR Only – Luminance and 1D LUT calibration

  • Here, you can adjust the monitor’s overall luminance setting to one that meets or exceeds your target luminance.

  • Click Measure and adjust the Brightness slider as needed.
  • In the Target Luminance box, you can also set the target luminance that the 1D LUT will achieve.
  • Click Next to proceed
  • Calman will now adjust the Multipoint Greyscale of the display using a 1D LUT.

  • Click the AutoCal button and select the number of data points in the AutoCal Dialog to auto-calibrate the Grayscale/Luminance response on the display.
  • Click OK to begin greyscale AutoCal.
  • When AutoCal is complete, click the Next button to proceed.

Step 7

  • On this page, Calman will calibrate the color gamut using a 3D LUT or Matrix, depending on the mode chosen in step 
3D LUT Matrix

  • Click the AutoCal button to open the AutoCal dialog
    • Recommended LUT types:
      • SDR: Lightning LUT
      • HDR: Fixed-Grid LUT
  • Click OK to begin the colorspace AutoCal process
  • When AutoCal is complete, click the Next button to proceed

SDR Only – Check Luminance

  • Click Measure to confirm your post-calibration luminance
    • Make small adjustments if needed
  • Click Next to proceed

Step 8

  • In this step, you’ll take measurements of the calibration results.

  • To take Post-Calibration Measurements, click the Measure button to measure the display’s grayscale and color response.
  • Click Next to proceed

  • On the Calibration Complete page, you can choose to…
    • Save and Report
      • Select Save and Report to generate the calibration report
    • View Comparison
      • Displays Pre and Post Calibration measurements of the calibrated mode side-by-side
    • Restart
      • Returns to the beginning of the workflow, where a new mode or colorspace can be selected
      • Note: Does not save workflow data
