ColourSpace can be integrated with FSI's range of XM professional reference monitors for accurate Closed Loop display profiling and calibration.
- ColourSpace Integration
- Closed Loop Profiling
- 3D LUTs
- Inbuilt TPG Operation
The following FSI displays have direct ColourSpace integration:
- XM311K, XM551U, XM650U, XM651U
All FSI displays equipped with 1st, 2nd, or 3rd generation Colour Fidelity Engines (CFE, CFE2, or CFE3) are compatible with ColourSpace for 3D LUT calibration, but lack direct integration. LUTs must be exported from ColourSpace and loaded into the display via FSI's provided update cable.
FSI display calibration is controlled via the Hardware Options menu, accessed via the Profiling window.
Before starting calibration, the display's own manual controls and OSD menus needs to be set correctly.
- Set all gain and bias rotary knob controls back to default
- Via the Colour menu set Colour System to ColourSpace/LightSpace and set the LUT Mode to your choice of Normal or Advanced
(ColourSpace is compatible with both modes and will automatically detect and load the correct LUT size and format for your LUT MODE
See FSI's own display user manual for details on Normal vs. Advanced Mode operation)
- Set Gamut selection to match the colour space you plan on calibrating for
(Rec709, P3, etc.)
- Set Luminance Mode to the desired setting
(100 for SDR, and 1000 HDR with the XM311K)
The last display menu selection to consider is the Range selection, which should be set to match the output range of your test pattern generator source. For example, if using Resolve as your test pattern generator set to Video Range, the display should also be set to Video Range. A mismatch between your test pattern generator output range and your display's Range setting will lead to an incorrect calibration result.
After the display has warmed-up, connect the network port to your local network, and the display will obtain an IP address via DHCP. If your display fails to obtain an IP address, unplug the ethernet cable, reboot the display, and connect the ethernet cable only after the display has completed its boot cycle. The assigned IP address can be seen from the monitor's System menu.
With the display correctly configured, ColourSpace needs setting-up.
- Open a ColourSpace Profiling window, select Hardware Options, and select FSI XM from the Hardware drop-down list
- Using the Network Address window enter the required IP address, and select Connect
- From the FSI XM Options menu select the Gamut memory slot to upload the LUT
(This selection should match the Gamut selection made previously on the display)
- To make sure there is no existing calibration data active within the display, select Unity Bypass from the Select LUT option, and press Upload
(To clear all the three LUT Slots, NULL will need to be uploaded to all three slots - 1D+3D, and Back 1D)
Note: Potentially, when Unity Bypass data is Uploaded 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.
As FSI displays do not have suitable in-built patch generation an external patch generator will be required, such as BoxIO, Resolve, or similar.
With your selected patch generator, profiling can then be performed as normal, using the probe connected to ColourSpace, with the external patch generator displaying the patches via the normal ColourSpace patch window.
Note: OLED displays can suffer from burn in, especially at high luminance. For this reason windowed patterns should not be used for extended periods of time on OLED base FSI displays.
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 it.
There are three LUT slots within the display, and the 1D+3D combination is the normal configuration to use for display calibration, with the Back 1D LUT left empty.
However, the Back 1D LUT could be used to pre-set the display's greyscale and gamma as a first pass, and then the display can be re-profiled with the Back 1D LUT active, and the 1D+3D LUT generated from the second profile pass uploaded for the final gamut calibration.
