BenQ Monitor Calibration Guide

For a 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 5.11.0 or later

Calman Workflow

• BenQ Monitor 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 PV270 (Matrix)
  
• BenQ SW270C (Matrix)
• BenQ SW271C (Matrix)
• BenQ SW321C (Matrix)
• BenQ SW272U (3D LUT or Matrix)
• BenQ SW272Q (3D LUT or Matrix)
• BenQ SW242Q (3D LUT or Matrix)

Step 1

• Welcome to the Calman BenQ 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 PV270/SW270C/SW321C or BenQ – SW272U/SW272Q/SW242Q

• 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.

Step 3

In this step, you can configure your calibration targets

• Colorspace
  • Preconfigured at Rec.709/sRGB
• Whitepoint
  • Preconfigured at D65
• Gamma Formula
  • Power Function is preconfigured, you may change the power function using the box to the right
•  

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
    • Supported on SW272Q/U and SW242Q
  • Matrix
    • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3×3 matrix for color gamut correction
    • Supported on all models
  • NOTE
    • 1. Each mode (1 or 2) can only store a 3D LUT OR a Matrix calibration, not both.
• Press Reset Current Mode to prepare the display for calibration
  • NOTE: This process may take up to 15 minutes

Step 6

• Luminance Target
  • Using the Brightness control for the monitor, displayed on screen, adjust to your luminance target.
    • Click the Read Continuous 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, you may need to target higher to account for the ambient light in your environment.
    • Below are some general luminance levels for different viewing environments (Supported levels are 45-250 cd/m^2)
      • Dim Room: 80-120 cd/m^2
      • Overhead lights: 120-160 cd/m^2
      • Bright Room: 200+ cd/m^2

Step 7

Press the AutoCal button to begin the Greyscale and Color Gamut 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.

Step 8

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 Read Continuous button to measure your monitors light output at 100% white and adjust the display’s peak white to the desired luminance.
• Press Stop when luminance adjustment is complete

Step 9

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

Click the Read Series […] button

• SDR 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.
