        • Failure to change from Video to PC levels will disable AutoCal functionality
        • Assure pattern source is also configured to PC (0-255) levels

CalMAN 3D LUT Calibration

Follow this procedure to automatically create and load an optimized 3D LUT monitor calibration file for a BenQ PV270 monitor. 3D LUT calibration is recommended based on time and accuracy factors.


Workflow Selection

The ColorCube (3D LUT) workflow in CalMAN is used to automatically create and load a 3D display calibration LUT.

For this purpose, it is required to skip the following step(s) of the workflow

  • 1D Ramp LUT (see next page for 1D LUT+Matrix calibration method)

For this purpose, it is optional to complete the  following step(s) of the workflow

  • Performance Analysis
  • Display Optimization
    • Display Presets, Mode Settings, Dynamic Range, RGB Adjust

Calibration Process

  1. Open ColorCube (3D LUT) workflow (CalMAN Menu > Open Workflow Template)
  2. Using Hardware Connect Page
    1. Connect your meter
      1. For SpectraCal C6 Meters, choose Meter Mode: “LCD (LED) BenQ PV270”
    2. Connect your pattern generation source
    3. Connect your BenQ PV270 to your computer using a USB A to B cable (Can be USB 3.0 or USB 2.0 A > B Cable)
      1. Choose “Find 3D LUT Device” and choose Manufacturer: BenQ and Model: BenQ PV270 (USB)
      2. Using Direct Display Control Dropdown, Display Mode: “Calibration 1 (3D LUT)” or “Calibration 2 (3D LUT)”
        1. “Calibration 1 (Matrix)” or “Calibration 2 (Matrix)” are used for 1D LUT+Matrix option in the following section. Each mode (1 or 2) can only store a 3D LUT OR a Matrix calibration, not both.
      3. Using Direct Display Control Dropdown choose “Full DDC Reset”
        • NOTE: This process may take up to 15 minutes
  3. Take pre-calibration readings on Display Pre-Test Gamma & ColorChecker page (Optional)
  4. Skip Display Optimization and 1D Ramp LUT steps
  5. On 3D Cube LUT page, click the AutoCal  button to begin AutoCal process
    1. Lightning LUT, Matrix LUT, or IRP Point/Time LUT creation methods are all valid. Lightning LUT is recommended based on time and accuracy factors.
    2. It may take several minutes to upload 3D LUT to monitor, CalMAN will confirm when complete

 


CalMAN 1D LUT & Color Matrix Calibration

Follow this procedure to automatically create and load an optimized 1D LUT monitor calibration file and color correction matrix for a BenQ PV270 monitor. Proceed through the instructions in each step of the SI Advanced Calibration workflow, using the following notes for BenQ monitor specifics.

Workflow Selection


The SI Advanced Workflow in CalMAN Video Pro, Studio, and Ultimate,  is used to automatically create and load a 1D display calibration LUT and color correction matrix.

For this purpose, it is required to skip the following step(s) of the workflow

  • Grayscale - 2pt
  • Base Settings (Color Temp, Gamma, Gamut, Dynamic Range, Resolution)

Calibration Process


  1. Open SI Advanced Workflow (CalMAN Menu > Open Workflow Template)
  2. Using Hardware Connect Page
    1. Connect your meter
      1. For SpectraCal C6 Meters, choose Meter Mode: “LCD (LED) BenQ PV270”
    2. Connect your pattern generation source
    3. Connect your BenQ PV270 to your computer using a USB A to B cable (Can be USB 3.0 or USB 2.0 A > B Cable)
      1. Choose “Find Display/Processor” and choose Manufacturer: BenQ and Model: BenQ PV270 (USB)
      2. Using Direct Display Control Dropdown, Display Mode: “Calibration 1 (Matrix)” or “Calibration 2 (Matrix)”
        1. “Calibration 1 (3D LUT)” or “Calibration 2 (3D LUT)” are used for 3D LUT method in the previous section. Each mode (1 or 2) can only store a 3D LUT OR a Matrix calibration, not both.
      3. Using Direct Display Control Dropdown choose “Full DDC Reset”
        • NOTE: This process may take up to 15 minutes
  3. Take pre-calibration readings on Pre-Calibration View page (Optional)
  4. Proceed from Pre-Calibration View page to Grayscale/Gamma Page, skipping all Mode Settings pages. (DDC reset from step 2 above sets correct pre-calibration values)
  5. On Grayscale/Gamma page, click the AutoCal  button to begin 1D LUT AutoCal process
    • NOTE: This process may take up to 30 minutes
  6. Once 1D LUT AutoCal is complete, proceed to Color Management System (CMS) Adjust Page
  7. On CMS Adjust Page, click the AutoCal  button to begin the Matrix color correction process
  8. Once CMS AutoCall is complete, proceed to Post Calibration View and verify calibration results
