i1 Display Pro OEM Probe

X-Rite i1 Display Pro OEM RevB Tristimulus Colourimeter

The X-Rite i1 Display Pro Probe is an ideal hardware companion to LightSpace CMS. A probe that can deliver quality results at a low price point, and performs well with all display devices, from projection to LCD, from plasma to CRT, and OLED, using contact and non-contact modes.


Overview

i1 Display Pro OEM Probe

The i1 Display 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.

Note: The OEM version of i1 Display Pro is NOT the same as the 'Retail' version, as the OEM version has an extended dynamic range, with a certified Max Luma capability of 2000 nits. The Retail version is certified to 1000 nits.
(The 2000 nits max luma capability was introduced Jan 2017)

LightSpace CMS Integration

As with all probes, the i1 Display Pro OEM operation and function is controlled via the 'Options' menu, accessed via the Calibration Interface, or Display Characterisation windows.

The i1 Display 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).
(This obviously ignores settings that are generic, such as Extra Delay Time, Probe Matching, Probe Offset, Luminance Units.)

i1 Display Pro Options

The options are:

  • Integration Time: sets the integration time 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.
  • 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.
  • Sync Mode: sets the sync mode for the probe, to best match the display refresh/sync operation.
    With the first iteration of the i1 Display 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.
  • Calibration Settings: using the drop-down menu any pre-set Matrix held with the i1 Display Pro can be selected.
    The Matrix presets match the probe to different display technologies - specifically the backlight/illumination spectral response.

If using the Probe Matching function (Active Probe/Display Data) to pre-profile a Tristimulus probe to a Spectro, the same 'preset matrix' should always be used for the Tristimulus probe as was used when the Probe Matching data was generated.

For further information on the additional settings within the 'Options' menu see the Profiling Manual page.

i1D3 NOTES

'Sync Mode' provide different methods for different types of display refresh operation.

Freq. Mode
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
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
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.
Note: BURST mode has been 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
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.
Note: 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 modes Frequency/Period/Burst modes to provide enhanced precision in low-light levels, if the integration time is set to an extended enough duration.

Note: 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
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 LightSpace 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.
