CalMAN Setup Guide
CalMAN takes advantage of the Blackmagic Design HDLink Pro features to calibrate a video display with
a 10-bit 17x17x17 3D cube lookup table (LUT). This setup guide assists you in calibrating the HDLink Pro
with the CalMAN Color Cube workflow.
Recommended CalMAN Workflow:

Color Cube (3D LUT)
Required HDLink Pro Firmware:

Version 3.5 or newer
HDLink Pro Control Connection:


USB A to USB B (printer) cable
USB driver contained in SpectraCal Device Driver Kit v2.3 or newer
CalMAN 3D LUT Display Calibration
CalMAN can calibrate the 3D LUT in the HDLink Pro either with a direct hardware connection or by
creating a software 3D LUT file and then using the Blackmagic HDLink Utility software to manually load
the software file into the HDLink Pro.
A. To create a LUT file with a direct hardware connection and automatically load the LUT into an
HDLink Pro, proceed with the Hardware LUT Load section, immediately below.
B. To create a software LUT file, skip to the Software LUT File section, further below.
CalMAN 3D LUT Display Calibration – Hardware LUT Load
CalMAN can calibrate the 3D LUT in the HDLink Pro with a direct USB control connection. To produce an
optimized 3D LUT calibrations file and automatically load it into the HDLink Pro:
1. In CalMAN, load the "Color Cube (3D LUT)" workflow.
2. On the CalMAN Settings tab (gear icon), under Workflow Basic Options, select either Video
(16-235) [SMPTE legal] or PC (0-255) [Full] to match the intended signal levels to be sent to
the display.
3. Proceed through each step of the workflow in the normal fashion, using the following notes
for guidance on the indicated workflow pages.
4. When you connect to your test pattern source, be sure to set the generator output levels,
Video (16-235) or PC (0-255), to match the signal content that will be processed through the
HDLink Pro. Also, set the generator for YCC (YCrCb) output.
5. On the Session Options page, select the Input Signal Levels, Video (16-235) or PC (0-255), to
match the signal content that will be processed through the HDLink Pro.

6. On the Session Setup page, click the Find 3D LUT Device button, then select "Blackmagic
Design – HDLink Pro (USB).”
7. On the Dynamic Range page, adjust the display’s black level/Brightness control to the black
level of the signal content that will be processed through the HDLink Pro (16 for video or 0
for PC/full range).
8. On the RGB Adjust page, under the RGB Adjust Levels selection, select “2 Point 30, 100%.”
Click Read Continuous and adjust the display’s RGB Gain controls for RGB balance at 100%.
Adjust the display’s RGB Offset/Bias controls (if provided) for RGB balance at 30%.
9. Skip the 1D Ramp LUT page (a 1D LUT does not need to be created).
10. On the 3D Cube LUT page, click the AutoCal (rotating arrows) button at the right end of the
meter action buttons. The AutoCal Setup dialog then appears (see below).
A. Under File Path, select the desired directory path and provide a name for the LUT file
that CalMAN will create (e.g. monitor ID and date).
B. Under Calibration Type, select the desired type of 3D LUT calibration process.

IR Profile (time based): Creates the best quality display calibration 3D LUT
possible in the selected period of time. You select how much display quality you
have time for, from 30 minutes to maximum display quality (6,000 points max).
Uses Intelligent Resolution Profiling to search out the most nonlinear color
space areas and correct those first.


IR Profile (point based): Creates the best quality display calibration 3D LUT
possible with the selected number of measurement points (1,000 - 10,000
points). Uses Intelligent Resolution Profiling to search out the most nonlinear
color space areas and correct those first.

Lightning LUT: Creates a display calibration 3D LUT in five minutes or less.
Produces a very high quality result on professional displays with moderate
linearity. Displays with significant nonlinearity may produce marginal results.
C. Under Video Range, select “SMPTE (16-235)” if you are calibrating a video display that
clips signal values above reference white.
D. Click OK.
Upon completion of the AutoCal 3D hardware LUT calibration process, CalMAN automatically loads the
optimized 17x17x17 LUT calibration data into the HDLink Pro.
DONE – HDLink Pro 3D LUT calibration and setup is complete.
Potential Crash Warning
With Windows 8, there may be instability with the HDLink Pro driver that causes a CalMAN crash during
the automatic LUT data load. CalMAN saves the LUT data to the CalMAN LUTs folder before attempting
to load the data into the HDLink Pro, so you won’t need to run the calibration again. If CalMAN crashes
during the data load process, perform the following steps to load the saved LUT data into the HDLink
Pro.
1.
2.
3.
4.
5.
6.
Reopen CalMAN and connect to the HDLink Pro on the Display Control tab.
On the Display Control tab, click the Open DDC Window button.
Scroll left or right to the 3D LUT Controls screen.
Click the Load LUT button.
Select the LUT that you just created.
Click the Commit button.
The LUT data that was created before the CalMAN crash will be loaded into the HDLink Pro.

CalMAN 3D LUT Display Calibration – Software LUT File
CalMAN can also create a 3D LUT display calibration file for the HDLink Pro, without immediately loading
the file into the HDLink Pro. The HDLink Pro does not need to be available during this display calibration
and file creation process. The file created will be a .3dl file with the proper HDLink Pro data format for
later loading into the HDLink Pro with CalMAN (as detailed below).
To create a 3D LUT display calibration file for the HDLink Pro with CalMAN:
1. In the CalMAN main menu, select Open Workflow Template, then select the ‘Color Cube (3D
LUT)’ workflow.
2. On the CalMAN Display Control tab, connect to the SpectraCal Cube Generator as a Display
Control device.
3. On the Display Control tab, under ‘File Format,’ select ‘3DL – common .3dl formats.’
4. On the Display Control tab, under ‘File Path,’ select your desired destination for the .3dl LUT file.
5. On the CalMAN Source Settings tab, select your desired test pattern source for display
calibration.
6. Follow the display calibration instructions in the ‘CalMAN 3D LUT Display Calibration’ section
above.
7. On the AutoCal Setup popup dialog, under ‘Output Cube Size,’ select 17. Under ‘Bit Depth,’
select 10.
Done: Upon completion of the AutoCal 3D LUT calibration process, CalMAN automatically writes a .3dl
file, containing color cube display calibration data, to your selected file destination. This display
calibration file can be later loaded to an HDLink Pro, using the procedure in the ‘ CalMAN 3D LUT File
Load to HDLink Pro’ section below.
CalMAN 3D LUT File Load to HDLink Pro
CalMAN can load a properly formatted 3D LUT file into the HDLink Pro. The LUT needs to be a .3dl LUT
file with a bit depth of 10 bits and 17x17x17 data points, with the data points at the following bit levels:
0,64,128,192,256,320,384,448,512,576,640,704,768,832,896,960,1023.
This .3dl LUT file can be a display calibration LUT created with the CalMAN Cube Generator function (as
detailed above). Or, it can be a creative (look) LUT created by any other application (with the proper
data points). During the load process, CalMAN converts the .3dl file into the file format required by the
HDLink Pro.
To load a 3D LUT file into an HDLink Pro:
1.
2.
3.
4.
5.
In CalMAN, on the Display Control tab, connect to the HDLink Pro as a Display Control device.
On the Display Control tab, click the ‘Open DDC Window’ button.
On the DDC Controls dialog, scroll to the ‘3D LUT Controls’ page.
Click the ‘Load LUT File’ button.
In the resulting file navigation window, select the .3dl LUT file that has been created for the
HDLink Pro.
Done: The selected 3D LUT file is now contained in the HDLink Pro.
