I bought a i1 display pro when Calman 5 first shipped, back in 2012. Date on the weight is 12/2011. Should I replace it or send it in to get calibrated?

Looks like a new one is 250 and calibrating is 2/3 of that price?

Is the pro versions from Chromapure worth it?
I understand a license file has the corrections in it, but it will only apply the corrections to Chromapure. Can the report be used to create a manual correction in Calman?

If the calibration data from Chromapure cannot be used in Calman is it worth switching to the Chromapure pro version and Chromapure standard vs sticking with a regular i1 display pro and Calman enthusiast?
 
The i1 Display Pro has glass dichroic filters that are sealed with rubber o-rings in it, they don't really shift very far overtime like older colorimeters.

We have some in the office from 2011 that have hardly shifted at all.

thanks, so don't worry about it then. :)
 
WiFi-Spy, it sounds like you know some profound details of the i1 Display Pro, so you might help me:
I "accidentaly" oppened my i1 Display Pro (don't ask why ;) ), so I saw the two O-Rings you mentioned (one next to the big front lens, one between the filters and the PCB). I haven't touched anything and put all back together after a few seconds.
Can this damage the sensor?
Like it was filled with some special gas, or I let humidity in which will destroy the filters?

Any advice highly appreciated!
 
As Tyler says, the i1D3's do not drift much over time, 'if they are looked after'.
Large temperature fluctuations, humidity, and excessive exposure to bright light are the potential killers.
And no, there are no 'inert gasses' used within the probe's manufacture (that X-Rite have ever discussed with us).

But, the RevB version of the i1D3 has a new AIO mode, which does give better, more stable results, on just about all display technologies, that the previous options.

It is worth 'upgrading' the probe for that alone.

Hi Steve, as we know the Rev.B has updated hardware/firmware that supports a new refresh rate detection and synchronization (AIO).

The new AIO (All in One) measurement mode for the i1Display Pro can improve the measurement stability for certain displays.

According to feedback I have from a Ted's LightSpace CMS Calibration Disk user which is using LightSpace HTL + i1DisplayPRO Rev.B + KURO + eeColor and he has performed a lot of testing using LightSpace's 'Measure and log' where it exports in excel (CVS) file format the xyY and the measuring times per each read in milliseconds, for us to find by comparing the data's which mode and integration time settings is giving him better repeatability while it has faster measuring speed (Test Procedure Link)....we found by comparing the data's between AIO vs. Burst Mode (Rev. A using Burst mode for Plasma) from i1DisplayPRO Rev.B Meter that that new AIO mode is about 30-50% faster from Burst Mode of Rev. A from the data I have.

From the info I have, AIO mode is not supported by CalMAN if someone has a Rev.B meter, but it's supported by LightSpace/HCFR/ArgyllCMS/DisplayCAL/ChromaPure.

I have this info directly from SpectraCAL support; from one friend who asked that question about Rev.B support with CalMAN.

No, ArgyllCMS/HCFR doesn't currently use AIO mode, because it doesn't need to. I implemented good synchronized measurements using the modes that are available in both the Rev A and Rev B.
 
OK, that sounds good to me.
I already have the Rev. B so no reason to get a new one.

The only problem that will last, who to trust: My brand new factory calibrated Monitor or the i1Display.
But that's an other story... :)
 
The Display Pro quick start guide says to store it between 20% and 80% relative humidity. Can storing them too dry be harmful to the seals?

I have been storing my two display pros in an airtight plastic bag with color changing silica gel bags and humidity indicator cards. When silica gel is not yet saturated the relative humidity is in 10% range.

Nothing to worry about, even reference meters which are coming with cases, they are air-tight shielded with a silica gel inside, just the manual has to provide some basic recommendation for all people.

Slightly off topic, but does the xrite i1 display pro calibrate colors and gamma for hdr? Can it measure nits up to 2000 nits?

Glad to see that these don't drift from my perspective too, thanks all!
All meters drift, there various reasons, humidity, temperature, how much its exposed to panel heat or to sun, to dust, to any accidental drop/shock, natural aging over the years etc.

BTW see how many C6 failed to pass a verification (original post there):

Also the refurbished C6s went through a rigorous testing process.

Here’s a picture of the box of meters that did not pass the accuracy testing process.

But profiling a colorimeter using a spectro as a reference, it can fix any drift and improve the meter's color accuracy.

A lot of details about that procedure can be found there: https://www.avsforum.com/forum/139-...um/139-display-calibration/3022414-four-color-matrix-meter-profling-thread.html
 
Hi!
I left my i1 Display Pro Plus on the table in its closed state for 48 hours in the living room with a standard lighting. So the light was passing through the white plastic cap (that is for surround measurements) into the probe for this time. It has been receiving 3-6 Lux and probably up to 30 lux half of the time (not sure what lights were turned on). Is it safe for its stability and accuracy over time? Or they are stable against time only, and not so stable against the light? I understand that this wasn't a very bright light (but lets go with the worst value of 30 lux), but for 48 hours straight! And it was plugged into usb port of my PC. Does it also affect anything? I mean, probably it's getting hotter inside when it's plugged in or something like that.
Thanks!
 
If you didn't have an application (I1 Profiler, CalMAN, ColourSpace, ChromaPure, etc) connected to the meter during that time, it's probably no big thing as it wasn't taking measurements.

Hi,

Don't worry about your meter.

i1Display PRO Plus can read more than 2000 nits; just up to 2000 nits will be valuable.

When you use the diffusor, it will reduce a lot the light, so a lot of less light will enter the meter optics.
