Appendix
Appendix 1: Tips and Tricks
Short on Time?
If you have time and want to generate optimal results a large test patch sequence (Cube Based Cube Size 17) is ideal. However, ColourSpace’s Grey Ramp RGB Large profile can generate extremely good calibration results very quickly. Keep in mind that the more linear the display is the better the results will be. You can start the Grey Ramp RGB Large profile by following the steps above. On the Display Characterization page select Grey Ramp RGB Large from the Mode drop down and complete the remaining steps.
DCI P3 Calibration
(applies to firmware 1.0.04-2254 and older only) If calibrating to a P3 target please note that the P3 setting on the monitor activates a unique gamma and white balance response separate from the standard settings. One of the two methods below may be used for accurate P3 calibration:
- You can follow the standard procedure outlined above and save your custom P3 calibration to one of the USER positions on the monitor (e.g. user1, user2, or user3). If using this method do not save to the P3 position on the monitor as you will get a poor result.
- The monitor may be placed in P3 mode and a unity LUT can be loaded to the P3 position. Then you will profile without bypassing the 3D LUT (bypass LUT set to none). When complete you will override the unity LUT loaded into the P3 position with your new 3D LUT.
OLED Black Level Setup and BT.1886 Calibration
The default black level of OLED monitors is effectively 0 nits (cd/m2), which
is well below the accurate or repeatable thresholds of most measuring devices.
A BT.1886 EOTF on a display with a black level of 0 nits is actually equal to
a 2.4 gamma response. For both of these reasons it is advisable to calibrate
to a target of 2.4 gamma when calibrating an OLED with black at 0 nits so that
noise or junk readings are not being factored into your calibration’s EOTF.
Once calibration is complete you can use the “bright” knob/key on the monitor
to adjust your black level higher if desired. When calibrated to a target of
2.4 with black at 0 the brightness rotary knob control maintains a BT.1886
response for any given black level. The appropriate black level is a function
of both viewing environment and personal preference, but a range of 0 nits to
no more than 0.05 nits is generally advisable.
Advanced Workflows
Custom 1D + 3D LUT and other advanced workflows are possible with FSI
monitors. For questions or details on advanced settings, workflows, and

Appendix 2: Calibration of DM250, DM220, & DM160
- Starting with firmware version 2.0.0-2282 you must use a back 1D + 3D workflow if calibrating DM250, DM220, or DM160 OLEDs with ColourSpace.
- The calibration process remains largely similar to the 3D LUT only procedure, but requires a few additional steps to first build and enable a 1D LUT.
- Start by setting the LUT Bypass toggle on the monitor’s system Menu to Both.
- Next, profile the monitor in ColourSpace using a Grey Ramp RGB or Grey Ramp RGB Large profile.
- Save this profile and then open a LUT Tools window in ColourSpace. Select your source (e.g. Rec709) and then for destination
- select the profile you just ran and saved. Next comes the most crucial step, when creating the LUT you will want to
- set the Max Luminance to 100 by selecting the checkbox next to max and manually entering a value of 100.
- Then click create LUT. Save the LUT and then from the Manage Spaces window in ColourSpace export the LUT you just created in the [1D] FSI_10bits (*.lut) format. Make sure to name this 1D LUT file user1.lut then copy / paste the file to the monitor’s memory.
- From the Color Management Menu on the monitor now select Update LUT to save the user1.lut 1D LUT to the monitor.
- Next change the LUT Bypass setting on the monitor from Both to 3D LUT. Then from the monitor’s Color Management menu set Custom Gamma to user1 to activate the 1D LUT you have just built and saved to the display.
- The rest of the calibration procedure then continues per the standard 3D LUT calibration instructions. When complete you will be using the combination of the USER1 Color Space setting and the USER1 Custom gamma setting.
Note: We suggest using an L32 (10%) patch size when calibrating OLED monitors to minimize the influence of loading behavior inherent to most OLED monitors.
