BenQ Monitor HDR Calibration

For compatible BenQ monitors, Calman can automatically calibrate the display by loading calibration data to the display’s internal 3D LUT or by using a combination of 1D LUT and color correction matrix.

Calman Required Version

• Calman (Ultimate or Studio) Version 5.13.0 or later

Calman Workflow

• BenQ Monitor HDR Calibration

 BenQ Firmware

• Firmware updates for BenQ monitors can be obtained by contacting BenQ support in your region

BenQ Control Port

• USB A to B cable

Calman Supported Models

• BenQ SW272U
• BenQ SW272Q
• BenQ SW242Q

Step 1

• Welcome to the Calman BenQ HDR Monitor Calibration Workflow, press Start Calibration to begin calibration

Step 2

Here you will connect to your BenQ Monitor and calibration hardware

• Connect to your BenQ Monitor to your computer using a USB A to B cable (Can be USB 3.0 or USB 2.0 A > B Cable)
  • On the Find Display dialog choose Manufacturer: BenQ and Model: BenQ – SW272U/SW272Q/SW242Q (USB)

• External Meter Connect
  • Press External Meter Connect button
  • On the Find Meters dialog, select your meter if it is listed, then click Search. If your meter is not listed on the Find Meters dialog, just click Search.
  • On the Meter Settings tab, under the Meter Mode drop-down, for a colorimeter select a meter mode appropriate for the display type you are calibrating. For a spectrophotometer, no special selection is required.
    • For C6 Meters select LCD (LED) BenQ

• External Source Connect
  • For a hardware test pattern generator, connect the generator to a control port on the Calman computer.
  • On the Source Settings tab, click the Find Source button.
  • On the Find Source dialog, select the Manufacturer and Model of your test pattern source device.
  • Select the Com Port, if appropriate.
  • Click Connect.

Note:

• Pattern generator should NOT send any HDR metadata.
• PG and display should both be set to Full Range.
• Internal Pattern Generator not supported for HDR calibration

Step 3

In this step, you can configure your calibration targets

• Colorspace
  • Rec.2020/ST 2084 HDR (PQ) targets
• Whitepoint
  • Preconfigured at D65
• Gamma Formula
  • ST 2084

Step 4

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

Step 5

• Select the display mode you wish to calibrate you can choose two methods for calibration. Connect via the method you wish you calibrate with.
  • 3D LUT
    • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3D LUT for color gamut correction
  • Matrix
    • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3×3 matrix for color gamut correction
  • NOTE
    • 1. Each mode (1 or 2) can only store a 3D LUT OR a Matrix calibration, not both.
      2. Each mode can only store an SDR OR an HDR calibration, not both
• Press Reset Current Mode to prepare the display for calibration
  • NOTE: This process may take up to 15 minutes

Step 6

Press the AutoCal button to begin the AutoCal process.

• Depending on the calibration method chosen in Step 2 this will complete a full calibration on your display including a greyscale 1D LUT (look-up table) and 3×3 Color Matrix, or a greyscale 1D LUT and a 3D LUT color cube.
• A Lightning LUT will take 101 measurements to create a 3D LUT and will take less than an hour
• The fixed cube options will take several thousand measurements and take a few hours to complete

Step 7

Here Post-calibration readings are taken to document the post-calibration condition of the display.

Click the Read Series […] button

• HDR Calibration now complete.
• Press the Save Config button to load the calibration to the monitor.
• Press Save and Report to save your Calman session file and open a report
• Or, Press Additional Validation to perform additional post-calibration tests with Saturation Sweeps and Pantone ColorChecker patches.
