ColourSpace can be integrated with Kroma's range of professional monitors for accurate Closed Loop display profiling and calibration.
- ColourSpace Integration
- Closed Loop Profiling
- Inbuilt TPG Operation
Kroma calibration is controlled via the Hardware Options menu, accessed via the Profiling window.
- If required, make sure the correct drivers are installed
(If necessary, verify via Windows Device Manager)
- Connect the Kroma display to the ColourSpace laptop via a USB or network connection as required, as well as a direct video connection with valid signal, and start ColourSpace
- Set the desired set-up options via the Settings menu, as required
- Open a ColourSpace Profiling window, select Hardware Options, and select Kroma from the Hardware drop-down list
- Either select the correct COMs port from the Serial Port drop-down, or select the Network Address window enter the required IP address, and select Connect
(If an IP address has been entered into the Network Address window it will be used by default)
- To make sure there is no existing calibration data active within the display, select Unity Bypass from the Select LUT option, and press Upload
- Using Calibration Patches select the desired patch option to use for profiling
(Automatic uses the patch settings defined within the ColourSpace Settings window, or else the closest available patch settings)
As soon as a Calibration Patches selection is made the Kroma display will show the patch colour as defined within the ColourSpace Manual Measure menu.
Potentially, when Unity Bypass data is Uploaded, potentially all settings will be nullified, not just the relevant LUTs. Should it be desired that settings other than the LUTs remain as set, upload a real Bypass 3D LUT (generated via LUT Tools/LUT Management/New), as that will only null the relevant LUTs, as selected. Alternatively, reset any necessary settings, such as Brightness/Contrast/Black-Level, after the Unity Bypass data Upload.
To profile the Kroma display with ColourSpace navigate to the desired profiling mode - Manual Measure or Display Characterisation.
The screen of the Kroma display will mimic the colour displayed, using the patch settings defined via Hardware Options.
Profiling can then be performed as normal, using the probe connected to ColourSpace, and with the Kroma screen displaying the required patches.
TV Legal Profiling Workflows
For Video Range profiling the Patch Scale function within the Settings menu will need to be used to scale the profiling patches correctly, as the patch Generator within the Kroma display is always Full Range.
After profiling, a Calibration LUT can be generated as normal within ColourSpace LUT Tools.
With the LUT still held within ColourSpace navigate back to the Hardware Options menu, and select the desired LUT from within the Select LUT options, and Upload.
TV Legal LUT Upload
After LUT generation the 3D LUT will need to have 'Video Scale' applied, to match the TV Legal range of the monitor, as the LUT needs to have video scale data within a data range LUT.
