Serial Connection Information

To connect the CalMAN calibration computer to a Samsung SUHD TV:
  1. Connect an ExLink adapter (3.5mm headphone jack to DB9 serial cable) between the 3.5mm jack on the side of the Samsung OneConnect box labeled “External Sync” and an RS232 port on your PC or to a USB to serial converter.
  2. If you are using a USB to serial converter, in Windows Device Manager, under “Ports (COM & LPT),” look for a “USB Serial Port (COMx)” listing.
  3. Note the listed COM port (COMx) of the serial converter.

USB to RS232 Serial Converter

For connecting to a Samsung TV with a computer that does not have an RS232 port, we recommend the FTDI USB to RS232 converter. Extensive testing has determined that this FTDI converter, which includes a data buffer, is the most reliable adapter to use for CalMAN device control.

SDR Calibration

Step 1

  • From the CalMAN Menu in the top-left, choose Open Workflow Template -> Display Specific and then AutoCal - Samsung
  • Select SDR Calibration to proceed down workflow steps for target colorspace

Connect your Colorimeter and Pattern Generator to CalMAN.

  • Plug your meter into a USB port on the computer and press the Find Meter button on the left
    • When your meter is connected, select your display type from the dropdown (this will vary by meter)
      • QLED: Quantum Dot LCD (LCD (LED Quantum Dot) – Samsung 2019 for C6 Meter)
  • Connect Pattern Source to your computer.
    • Click the Find Source button then select your source
    • Configure Pattern Generator
      • Pattern Size
        • Full Screen 100%
      • Pattern Delay
        • 2 Seconds

Connect to your Samsung TV for calibration

  • Connect an ExLink adapter (3.5mm headphone jack to DB9 serial cable) between the 3.5mm jack on the side of the Samsung OneConnect box labeled “External Sync” and an RS232 port on your PC or to a USB to serial converter.

  • If you are using a USB to serial converter, in Windows Device Manager, under “Ports (COM & LPT),” look for a “USB Serial Port (COMx)” listing.

  • Note the listed COM port (COMx) of the serial converter.

  • Click Find Display, select your model and COM port

Step 2

Confirm your calibration targets and prepare TV

  • Press Reset Targets
  • For SDR, calibration targets should be:
    • Rec709
    • D65
    • BT.1886

Step 3

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
    • This will provide a point of reference to compare your calibration results

Step 4

  • Select your target picture mode
    • Options are 
      • Movie
      • CAL-Day*
      • CAL-Night*
      • *Mode settings locked after calibration
  • Press Full DDC Reset
    • This will configure several of the TVs settings to the ideal values. 

Step 5

In this step, you will be able to adjust the Luminance of your display to match your desired target. Luminance is a subjective target. SDR reference luminance is 100cd/m2, but you may need to target higher to account for the ambient light in your environment.

  • Click the Measure Luminance 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. SDR reference luminance is 100nits, but you may need to target higher to account for the ambient light in your environment.
  • Adjust your TV's backlight control so your TV is about 15% brighter than your final target to account for a reduction in luminance when calibrating the 1D LUT in the next step
  • Press Stop when luminance adjustment is complete

Step 6

On this page, CalMAN will adjust your display's White Balance

  • Click the AutoCal button to perform the 2pt greyscale AutoCal

Step 7

Here CalMAN will adjust the Multipoint Greyscale of your display.

  • Press the AutoCal button and select the SDR greyscale points on the AutoCal dialog

Step 8

On this page, CalMAN will adjust the Colorspace/CMS controls on your display

  • Press the AutoCal button to open AutoCal dialog
    • All options are preconfigured
  • Click OK to begin colorspace AutoCal process

Step 9

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

  • Click the Read Series [...] button

SDR Calibration is now complete

  • Save and Report
    • Saves current session, and opens AutoCal Report
  • Calibrate Next Mode
    • Clears data and allows you to return to the beginning of the workflow and calibrate a new mode
  • Additional Validation
    • Allows additional validation with ColorChecker and Saturation Sweeps. 
    • Optional


HDR Calibration

Step 1

  • From the CalMAN Menu in the top-left, choose Open Workflow Template -> Display Specific and then AutoCal - Samsung
  • Select HDR Calibration to proceed down workflow steps for target colorspace

Connect your Colorimeter and Pattern Generator to CalMAN.

  • Plug your meter into a USB port on the computer and press the Find Meter button on the left
    • When your meter is connected, select your display type from the dropdown (this will vary by meter)
      • QLED: Quantum Dot LCD (LCD (LED Quantum Dot) – Samsung 2019 for C6 Meter)
  • Connect Pattern Source to your computer.
    • Click the Find Source button then select your source
    • Configure Pattern Generator
      • Pattern Size
        • Window 10%
      • Pattern Delay
        • 2 Seconds

Connect to your Samsung TV for calibration

  • Connect an ExLink adapter (3.5mm headphone jack to DB9 serial cable) between the 3.5mm jack on the side of the Samsung OneConnect box labeled “External Sync” and an RS232 port on your PC or to a USB to serial converter.

  • If you are using a USB to serial converter, in Windows Device Manager, under “Ports (COM & LPT),” look for a “USB Serial Port (COMx)” listing.

  • Note the listed COM port (COMx) of the serial converter.

  • Click Find Display, select your model and COM port

Step 2

Confirm your calibration targets and prepare TV

  • Press Reset Targets
  • For HDR, calibration targets should be:
    • rec.2020
    • D65
    • ST.2084
  • Hardware Options
    • Pattern Size
      • Window 10%

Step 3

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
    • This will provide a point of reference to compare your calibration results

Step 4

  • Select your target Movie - HDR picture mode
  • Press Full DDC Reset
    • This will configure several of the TVs settings to the ideal values. 

Step 5

In this step, you will raise or lower the contrast to best match the EOTF. Depending on your Samsung model and physical size, you will have different maximum luminance capabilities. This variability will cause each individual unit to track along the EOTF slightly differently.

  • First, press Read Series [...] to take an initial reading of the EOTF
    • If the EOTF is tracking above the yellow line, lower contrast until the lines best match. 
      • If the display is particularly bright (1800-2300nits), this value may need to be lowered to as much as 30-35
    • If the EOTF is tracking below the yellow line, raise contrast until the lines best match. 
      • If the display has a lower peak luminance (450-700nits), this value may need to be raised to the maximum of 50
  • Once the best contrast is found, proceed to the next step


Step 6

On this page, CalMAN will adjust your display's White Balance

  • Click the AutoCal button to perform the 2pt greyscale AutoCal

Greyscale Calibration Note:

Due to panel variability across various configurations of the QLED based TVs, the factory baseline EOTF settings can change the point alignment by model and panel size. Samsung QLED HDR calibration support has been updated to add in EOTF matching and remove MultiPoint Grayscale because of the variability. A combination of EOTF matching and a 2pt white balance produce excellent results across the range of supported QLED TVs and can be achieved quickly.

Step 7

  • Press the AutoCal button to open AutoCal dialog
    • All options are preconfigured
  • Click OK to begin colorspace AutoCal process

Step 8

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

  • Click the Read Series [...] button
