X-Rite i1Display Pro (i1D3), its various versions, including Retail and the expensive C6 variant

There is a lot of confusion regarding the X-Rite i1Display Pro probe (aka i1D3), and the various versions that are available from different suppliers.

A lot of this confusion has been generated by the C6 provided by Portrait Displays/Calman.

The C6 is JUST an expensive i1Display Pro OEM - and is no different in any way at all to the normal i1Display Pro OEM.
It has a different paint job, but that is all.
Even the 'calibration' certificate provided with it is invalid, and is not NIST traceable, even though Portrait suggests it is.
(It just defines a set of measurements that are no different from any other i1Dispaly Pro OEM... no 'correction' has been applied to the probe, as that is not possible outside the use of an EDR, and the 'light source' and 'comparison probe' Portrait use are not valid for a NIST traceable set of values.)

The one difference with the C6 is when used with Calman software, as it acts as a key to unlock preset EDRs held within Calman.
(These EDRs have nothing to do with the C6 itself, and could just as easily be used with any i1Display Pro, if they were not 'locked'.)

But, there are also a number of EDRs available for the standard i1Display Pro variants, including the WOLED EDR we make available for download via this website, as well as being standard within ColourSpace.

And more importantly, using a Spectro to perform probe matching is more accurate on any given display, and the extra cost for the C6 would be better used to put towards purchasing an i1Pro 3...

In addition to the C6, which we now know is just an OEM i1D3 in drag, there are two Retail versions.
(There are also other specific manufacturer versions, such as from HP, NEC, ASUS, Wacom...)

The first is the 'standard i1Display Pro, which is X-Rite certified to 1000 nits.
And then the i1Display Pro Plus, which is a Retail version of the i1Display Pro OEM, X-Rite certify to 2000 nits.

The i1Display Pro OEM; the i1Display Pro Plus; and the Calman C6 are all the EXACT same probe, with the exact same capabilities/accuracy.
So why the different names for the exact same probe, you ask..?
A very good question.

The only difference is that X-Rite have chosen to limit the software systems the Retail vs. OEM versions can work with, in a similar way to the C6 being locked to Calman use.

Why this has been done we do not really understand, and neither do we agree with it.

But luckily, with Light Illusion software there are solutions from 3rd parties.
See this thread on the Retail i1D3.
