Profiling the XM310K
Next select either the Calibration Interface or Display Characterization icons to begin profiling the monitor. Grey
Only Large (Calibration Interface) is suggested for PQ based calibration. Grey Only (Calibration Interface) or
17x17x17 Display Characterization are suggested for SDR calibrations.
From the Display Characterization / Calibration Interface window select Options. Make sure the CR100 serial
number is listed at top of the options window. Set Extra Delay Time to 1.0 Seconds.
To Sync the CR100 set Sync Frequency to Manual and select Probe Calibration. Follow the prompt and click Ok.
It may be advisable to type in a custom number here based on your source frame rate, contact FSI support if you
have questions about this selection. With the monitor in Dynamic Luminance Mode using AUTO sync is advis-
able. Under Calibration Settings, select the correct calibration matrix that is stored on the CR100. Then press Ok.
Next place your CR100 probe at the center of the monitor and press the Measure (Display Characterization) or
Profile (Calibration Interface) button. A dialog window will ask you to give your
profile a name
. Select something
easily identifiable and press OK to begin the profiling process.
Once your profile completes select the Convert Colour Space icon.
In the Convert Colour Space window enter your desired LUT name in the NAME field.
From the source dialog select your target colour space from the colour space dropdown menu (e.g. Rec709).
From the destination dialog select your
calibration profile
. Then click create new to generate your calibration
LUT.
Once your LUT is generated select File, then Upload. From the upload dialog make sure NULL Cube is un-
checked. Select 1D + 3D, verify you are saving to the correct memory position option, and then press Upload.
This will save the calibration LUTs to the Front 1D and 3D LUT calibration positions. Your calibration is now
complete.
Additional Considerations
If you plan on utilizing the Back 1D LUT (static backlight selections only) for calibration please remember to cal-
ibrate for this position first, upload to the monitor, then profile with this Back 1D LUT active.
When profiling in Dynamic (modulated backlight) Luminance Mode the baseline EOTF and peak luminance be-
havior are determined by the monitor menu’s EOTF settings. Gamma EOTF selections (e.g. 2.4) will result in a
baseline gamma response and an SDR appropriate peak luminance. PQ and HLG EOTFs will have correspond-
ing baseline PQ (hard clip) or HLG EOTFs with HDR appropriate peak luminance settings.
When profiling a display with a PQ baseline EOTF in LightSpace it may be advisable to use the patch scale func-
tionality to only generate test patches to the hard clip value of the display. If doing so you should apply the inverse
of the patch scale to the resulting 3D LUT using the Maths functionality. For example if scaling the patch set from
0 to 217 you would want to append the maths operation approximatley as (R = r*.85, B = b*0.85, G = g*0.85).
