Calibrating the Dell UP2720 with Calman

June 10, 2026

Calman can guide the calibration of the Dell UltraSharp 27 4K PremierColor Monitor (UP2720Q), delivering accurate color and luminance performance using a 1D and 3D LUT. The UP2720Q features a 27″ IPS panel with 100% Adobe RGB and 98% DCI-P3 coverage, making it well-suited for color-critical workflows.

Calman Required Version

  • Calman Studio or Ultimate v5.15.3 or higher

Hardware Requirements

Step 1

  • From the Calman Menu in the top-left, choose Open Workflow Template -> Calman Ready and then Dell U2720Q Calibration.

  • Click Next to begin.

Step 2

 

  • Connect to the monitor, its built-in colorimeter and pattern generator:
    • Connect the monitor to your computer using a USB-C to USB-C (Thunderbolt/USB4) or USB-C to USB-A cable.
    • Click the Find Dell Monitor button to connect the monitor for calibration, using its built-in pattern generator.
    • Connect to either UltraSharpUP2720Q 3DLUT (USB) or UltraSharpUP2720Q Matrix (USB)
      • 3D LUT is more detailed, but will extend the calibration time needed
      • Matrix mode will calibrate faster, but may not be as accurate overall
  • Connect your external meter:
    • Connect the meter to the computer running Calman.
    • Press Connect External Meter.
  • (Optional) To use an external pattern generator:
    • Press Find External Source and follow the prompts to connect to the pattern source.
      • After connecting, use a Window 10% pattern with a 1 second delay for best results.
  • Click Next to begin calibration

Step 3

  • Confirm or adjust your calibration targets, then click Next to proceed.
    • Colorspace – Preconfigured at Rec.709/sRGB.
      • Note: UP2720 only supports SDR calibration
    • Whitepoint – Preconfigured at D65.
    • Gamma Formula – Preconfigured at Power 2.2.
    • Luminance Target – Preconfigured at 200 cd/m². Supported range is 45–250 cd/m².
      • Dim room: 80–120 cd/m²
      • Overhead lights: 120–160 cd/m²
      • Bright room: 200+ cd/m²
  • (Optional) Custom Targets – Targets can be created by manually entering values or by measuring a reference display.
    • Open Pattern Window – Measures a monitor connected to the same computer.
    • Connect to Client3 – Measures a monitor connected to a separate computer. Client3 can be downloaded free of charge from Portrait.com.
    • Connect to VideoForge Pro – Measures another display via a pattern generator.

Step 4

  • 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 grayscale and color response.
    • This will provide a point of reference to compare the calibration results.
  • Click Next to proceed

Step 5

  • Depending on the calibration type (3D LUT or Matrix) chosen in Step 2 this step will vary slightly
3D LUT Matrix
  • Press the AutoCal button to calibrate the 1D and 3D LUTs for your monitor.

  • Press the AutoCal button to calibrate the 1D LUT and 3×3 color matrix for your monitor.
  • Once complete, click Next to proceed.

Step 6

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

  • To take Post-Calibration Measurements, click the Read Series button to measure the display’s grayscale and color response.
    • After the full Post-Calibration measurement has been completed, an additional set of measurements will be taken and uploaded to the monitor’s internal validation service. Please wait for this to complete before proceeding.
  • Calibration is now complete. If you wish to save your calibration session for later reference, click Save Data in the bottom-right corner.
