The X-Rite i1Display Pro OEM probe can deliver quality results at a low price point, and performs well with all display devices using contact and non-contact modes.
- ColourSpace Integration
- Large Spot Size
- Glass Filters
- Low Cost
- 0.1 to 2000 cd/m2
- Spectral calibration architecture
The i1Display Pro OEM - RevB is factory calibrated using multiple display devices, making the it very accurate in a wide range of display applications.
It utilises a 3 filter design with custom curve shaping for excellent CIE colour matching functions, as well as superior sensitivity, and has been specifically designed for modern display technologies, including direct displays and projectors, up to 2000 nits brightness.
Due to X-Rite limitations many manufacturer specific calibration systems will only work with the OEM version of the i1Display Pro, and will not work with the Retail versions.

Measurement performance data is based on X-Rite's manufacturing standards, equipment, and conditions, and is not guaranteed outside of X-Rite's own environment.
As with all probes, i1Display Pro operation and function is controlled via the Probe Options menu, accessed via the Profiling window.
The i1Display Pro has a range of variables that are directly associated with the probe - including Integration Time, Display Type, and probe Calibration Settings (Matrix pre-sets) - as well as generic probe settings, such as Extra Delay Time, Probe Matching, Probe Offset, etc.
Calibration Settings provides generic probe settings and preset Matrix options, as well as Intelligent Integration, which is unique to the i1Display Pro's operation with Light Illusion calibration software.
The Drop-down menu provides access to the pre-set Matrices held within ColourSpace for the i1Display Pro.
The Matrix presets match the probe to different display technologies - specifically the backlight/illumination spectral response - using EDR (Emissive Display Reference) files, held within ColourSpace, not the probe itself.

Light Illusion has added a number of additional EDRs to the default X-Rite standard files, including the WOLED EDR.
Intelligent Integration sets the nits level under which Intelligent Integration will be used.
This provides the best possible low-light measurements, without impacting reading speeds at luma levels above the set value, so maintaining overall speed of profiling.
Average Low Light
Average Low Light is a probe generic option, that averages multiple readings in low-light situations using an advanced algorithm built into ColourSpace. The algorithm varies based on the probe in use to provide the best possible results.
Average Low Light should not need to be used when Intelligent Integration is active.
Enable Visible Feedback
Enable Visible Feedback enables the i1Display Pro's LED, providing feedback on the status of the probe - idle, or taking measurements.
The LED will not match every measurement when readings are fast.
Integration Time sets the time taken for any given reading, in seconds.
There is no default setting, as different values will be required depending on the display being profiled, with longer values generating more accurate and stable readings.
Sync Mode sets the mode to best match the display refresh/sync operation.
With the first iteration of the i1Display Pro only Frequency, Period, and BURST are available. With RevB versions of the probe AIO (All In One) mode is the better option for most display types.
Extra Delay Time
Extra Delay sets a time after the patch has been changed before probe measurement starts.
This can deal with delays in the image pipeline.
Probe Matching is used to match the i1Display Pro Tristimulus to a Spectroradiometer, increasing the profile accuracy.
There are two different methods available for probe matching - 4 Colour Volumetric Matching (FCVM), and Multi-point Volumetric Matching (MPVM).
ColourSpace doesn't use the older, traditional, 4 Colour Matrix (FCMM) Method for probe matching, as the volumetric approach offers far greater probe matching accuracy.
Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.
Sync Mode provide different methods for different types of display refresh operation.
Frequency mode is best suited to displays that have an inherent low-frequency flicker, typically less than 150Hz, as with CRT displays and some LCD displays with CCFL backlights. A possible restriction is that at extreme low-light levels precision may be reduced, unless the integration time is set to a high value.
(Frequency mode measures the number of flicker pulses over the set Integration Time, and normalises the result by the integration time to attain the flicker frequency.)
Period mode is best suited to displays that do not flicker, or flicker at a very high frequency, above than 5000Hz. On such displays this mode will have higher precision at extreme low-light levels.
Period mode measures the time between a set number of flicker pulses, within the set Integration Time, and divides the measure time by the number of flicker pulses to attain the flicker frequency.
BURST mode is an alternative mode aimed at displays with flicker that changes with light output levels, or 'pulse', as with PWM (Pulse Width Modulation) on displays such as Plasmas, OLEDs and DLP projectors.
BURST mode was depreciated with the introduction of AIO mode on RevB versions of the i1D3, but may still be preferable on some displays with variable flicker/dithering, and for use on RevA probes.
AIO mode is a combination of Frequency and Period modes, and has the capability to synchronize with all displays of any given flicker/frequency, and is the suggested mode for most display types.
AIO mode is only implemented in the later RevB versions of the i1D3 probe.
As with any set of 'rules', in the real world nothing is written in stone. And with displays that use PWM, or other frequency/flicker based technologies, there is potential for the alternative Frequency/Period/Burst modes to provide enhanced precision in low-light levels, if the integration time is set to an extended enough duration, especially through the use of Intelligent Integration.
When the i1D3 attempts to measure levels below its minimum capability it may return measurement data that is 'generic', depending on the Sync mode selected. This tends to be more prevalent in Frequency mode.
Intelligent Integration set a nits value below which the i1D3 will perform a second, third, fourth, etc. reading, with increasing integration times, up to the maximum integration time of 6 seconds. The readings will stop as soon as a stable and valid reading is achieved. If no valid and stable reading is achieved a 'zero' value will be returned, enabling ColourSpace to intelligently calculate a replacement value when generating a calibration LUT.
With the addition of Intelligent Integration, for many display types the use of Frequency Mode may prove to provide the best possible measurements, as the integration time will be extended below the set Nits level, overcoming the inherent limitation with Frequency Mode when used without Intelligent Integration. But be aware Frequency mode is NOT suitable for all display types - OLEDs for example.
