Dell Color Management

Calman works in conjunction with the Dell Color Management companion application to store and manage calibration profiles and other settings. This allows you to have multiple calibrations saved which can be applied on-the-fly to the calibration colorspace slots. 


Calman Supported Models

  • UltraSharp UP2720Q

Step 1

  • Welcome to Calman for Dell, press Next to begin calibration

Step 2

Here you will connect to your Dell Monitor and calibration hardware

  • Connect to your Dell Monitor
    • Note: If you're using a Thunderbolt 3 cable for your video connection, no extra cables are needed, If you're using HDMI or DisplayPort for your video connection, you will also need to connect a USB cable between your computer and your monitor. This can be a Thunderbolt 3 cable or a USB-A to USB-C cable (with the USB-C end plugged into the 90W Thunderbolt 3 port on the back of the monitor
    • Click Connect Dell Monitor
      • On the Find Display dialog, you can choose two methods for calibration. Connect via the method you wish you calibrate with. IMPORTANT: A dialog will be displayed on the Dell monitor, choose YES to allow connection
        • Dell UltraSharp UP2720Q 3D LUT
          • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3D LUT for color gamut correction
        • Dell UltraSharp UP2720Q Matrix
          • Calibrates the monitor using a 1D LUT for grayscale calibration, and a 3x3 matrix for color gamut correction
    • (Optional) Correlate Internal Sensor
      • This will profile the internal meter to your specific display type, using a reference colorimeter.
  • 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.
  • 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: For the Dell internal color sensor to read test patterns, Full Screen 100% test pattern size must be used. If you are using an external meter, any window size can be used as long as the meter is placed in front of it


(Optional) Correlate Internal Sensor

If you chose to correlate the internal color sensor on the hardware connect page, you will be walked through the following steps to create a meter profile for the internal sensor

  • This page will assist you in gathering data from the reference meter
    • If needed, you can switch to the reference device in the Meter Dropdown
  • Press Read Series [...] to gather reference data

  • This page will assist in the creation of the meter profile
  • Select the correct target and reference meter 
    • Reference Meter – This should be the external meter
    • Target Meter – This should be the Dell internal sensor
  • Configure your source
    • In most cases Stimulus Level 100 is appropriate
  • Click on the Add Profile button to initiate a new profile.
    • The Multi-Pass option is recommended for correlating the Dell internal sensor to your external meter. Each meter will read at a selected position on the display, one at a time. The Calman Meter Profile process then prompts you to measure the display with both your reference meter and your internal meter. Each meter measures four colors in just seconds; white, red, green, and blue.
  • Select the Meter (factory) mode. This will give the new profile a baseline to be adjusted from. 
    • Calman creates a Four-Color Correction Matrix for your colorimeter, based on the differences between the spectrophotometer measurement data and the colorimeter measurement data. The Four-Color Correction Matrix is an industry-standard technology developed by the National Institute of Standards and Technology (NIST).

  • This page will gather data to validate the new meter profile

  • Here you can compare readings from the new meter profile, against the data that was gathered from the reference meter.
    • Note: The same color must be chosen in the top left in order for results to be displayed. 

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
  • Luminance Target
    •  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

(Optional) Custom Targets/Display Match

  • Targets can be created by manually entering target values, or measuring a target display:
    • To measure a monitor connected to this computer open a pattern window using the Open Pattern Window button.
    • To measure a monitor on another computer, including a seperate laptop, press the Connect to Client3 button.
      • Client3 can be downloaded free of charge from the Portrait Displays website.
    • To measure a phone or tablet press the Connect to Mobile Forge Button
      • MobileForge can be downloaded free of charge from the Apple App Store or Google Play
    • To measure another display using a pattern generator, press the Connect to VideoForge Pro button.

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
  • With the Autosave option selected Calman will automatically continue to step 7

Step 5

  • 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 3x3 Color Matrix, or a greyscale 1D LUT and a 3D LUT color cube. 

Step 6

  • Measure the display with a combination of a grayscale and X-Rite/Pantone ColorChecker patterns. This provides an accurate assessment of the display following calibration and will be represented along with the pre-calibration readings on the next page
  • Click the Read Series [...] button to measure the display's grayscale and ColorChecker® response.

Step 7

Calman for Dell will now export a Calibration Exchange file to the location of your choice, which can then be imported into Dell Color Management. This allows you to have multiple calibrations saved which can be applied on-the-fly to the calibration colorspace slots. 
  • On the Post-Calibration page above, click Save Data in the bottom right of Calman.
  • On the File Save Dialog, name the calibration exchange file and choose a save location. 

Step 8

  • Open Dell Color Management
    • Note: Calman for Dell will need to be closed before Dell Color Management can communicate with the display
  • The Dashboard page will give you an overall view of the colorspaces available on the display.
  • Click Advanced

  • From the Advanced tab, choose the color space that was targeted in Calman (Cal1 or Cal2)
  • Click the Targets button

  • To import your newly created calibration file, click Import and choose the file from the file browser
  • To load a previously imported calibration, select it and click Load
  • To remove a calibration, click Remove
