Really I am looking for reassurance that this meter has been tested at the range of 'working temperatures' it is likely to encounter during 'contact operation' and that it maintains its accuracy, by whatever means, across this range of its many modes.

Perhaps it has temperature compensation inbuilt, perhaps software automatically adjusts for it or perhaps it is totally unnaffected by temperature variations?

Apologies if I have not been clear.

Yes the D3 family has a built in temperature compensator so contact or non works just fine.

Thanks Derek,

So it definitely maintains the same accuracy which presumably your lab technicians have checked?

I use contact mode with the D3Pro on my LG LCD, LED back lit with perfect results.
The display screen is barely warm with the Back light ~ 15 which is plenty bright and reduces the power consumption to ~ 75 watts and is my normal operation mode.

And it avoids errors due to ambient illumination in the viewing environment.

Good idea re backlight setting.

I usually set contast as best I can then adjust backlight to get correct output at 100 IRE.
Am I better maximising my contrast and reducing my backlight?

Absolutely.

Backlight raises black levels, reducing the contrast ratio of the set. Lowering the contrast control does not lower black levels.

Use the contrast control to optimize your contrast ratio, then use the backlight to hit your target light output.

Yes, but check a white clipping test pattern to avoid clipping whites and also to avoid discoloration.

Thanks, it passes the clipping patterns (say S & M ) if I reduce the contrast output from my Duo.
No chance with TV controls though.

Incidentally, on a different point I am now using the D3 and as you suggested it is at variance with the D2.

Results for my 100 IRE pattern on D3 are x = 0.313 y = 0.329.
Changing back to D2 I get x = 0.336 y = 0.329
or if you prefer:
Red = 128.9%
green = 92.4%
blue = 92.6%

Which is a strange result because it means that when D2 shows correctly it would be short of red rather than having too much.
But you were right (if D3 is accurate), my D2 is incorrect.

That sounds exactly like what you'd expect with a drifted D2.

Perhaps you can try dialing in just 10% and 100% white with the D2 and just eyeball them to see if they look on the red side. If its drifted, you should be able to tell. At 128% for red, it shouldn't be too subtle.

While many D2's are known for under reporting red, the unit to unit variation is enough to make each D2 off in a different direction. Also, as the meter gets older the red filter degrades the fastest in the D2 and this is a key reason why most D2 owners report the meter under reading red and causing you to compenate by adding too much red into the grayscale.

You are misunderstanding his post. When the display is set to D65 with the D3 and then he takes a reading with the D2, it overreads red compared to the D3. If the display was adjusted to D65 with the D2, he would have to compensate for the high red reading by removing red from the grayscale, resulting in an image that is red deficient.

No misunderstanding. He is reporting a difference between the D2 and D3 when reading a 100IRE sample. I'm merely pointing out a simple way in which he can confirm the D3 as accurate and the D2 as drifted.

I have the calibration correct to D3 now so that is the reading my old D2 gives when it measures the D3 corrected pattern.
Luckily I have a CP Pro licence which allows me more than one meter, so I can initialise and change meters easily during the same session.

Obviously if I did correct the pattern with the D2 I would get less red which is what I observe now that my corrected with D3 picture shows more red.

That last para was supposed to make my point of view clearer, I feel I may have complicated it?

All good. On the same page now.

One more thing on Calman,

Technically, will the software recognise (with the appropriate license) and use the i1Pro uv-cut meter? This is just to calibrate colorimeters.

Note, I am not asking for uv-cut vs non uv-cut i1pro's discussion here.

Thanks again.

Using the i1PRO For Emissive Calibration (Displays, Projectors) there's no difference between the UV-Cut Filter and Without Filter Versions of the instrument.

CalMAN is currently supporting both modes.

Yes CalMAN supports the i1Pro uv-cut and standard. We support both versions in luminance, illuminance and reflective.

Anyone verify if the OEM version of the meter is compatible with NEC SpectraView software for internally calibrating their monitors?

According to one of the NEC reps, they support 3 versions of the D3 meter:

"SpectraView II only supports the NEC SpectraSensor Pro, X-Rite iOne Display Pro, and what X-Rite calls "low volume generic OEM" versions."

I'm considering picking up ChromaPure in the future and would like a meter that works with both. Not sure if any of the 3 options listed above would work in CP.

Unless OEM works in both software, it looks like Calman and retail meter are the only known working solution for SpectraView users.

"low volume generic OEM" is the OEM version

I have an OEM and bought it because it is not restricted to just one make of software like the Retail version.

Don't know about the NEC but confirm it operates perfectly with both Calman v4 and Chromapure Pro.

are the i1 display 3 pro from ChromaPure and the i1 display pro from Spectracal the same meter?

are there any significant differences in the basic level of these 2 software packages?

I'm considering upgrading, but find the information on the 2 web sites confusing. I have a CalMan V3 license now. I'm guessing I would have to upgrade to V4. I have emailed Spectracal twice in the past week about upgrade pricing, but haven't recieved an answer as yet.

The Calman DIY with the i1 display pro meter is $439
The ChromaPure Standard with the i1 diplay 3 pro meter is $569

thanks in advance
post #1101 of 1402
I may have been able to tell you a few months ago as I was researching the difference products myself, but I found it too confusing with all the OEM, retail, licensing issues, etc, etc... and gave up.

I'll look back into it soon, but gave up during the holidays.

Sorry no help, good luck.

The meter from spectracal does not have as many customer tables for different display types as the one from Chromapure. If you want lots of custom correction tables from Spectracal you have to buy there C6 which is a modified i1D3 with additional tables, and different firmware and a NIST cert of accuracy and a real nice case to store it and transport it in. And the most expensive of the 3.
I went with the C6, call Spectracal and talk to them about your options rather than email.

I get copies of our in bound emails for sales and support but have not seen any about this, so it looks like your emails are not making it.

You can email me directly derek@ or give us a call. Yes you will need to upgrade to v4 for D3/C6 support.

X-Rite builds four versions of the D3. They look the same but do have differences. They should have called them all something different.

ColorMunki Display - the cheapest but also the slowest and only works with X-Rite software which is very limited.

Display Pro - retail version has support for 4-6 display types and is designed to run only with X-Rite software. A couple OEM vendors have been able to license access including CalMAN.

Display3 OEM - Which everyone has access to has factory support for 4-6 display types. Most OEM products support this version of the D3.

Display3 Pro – Same as the D3 OEM but what ChromaPure sell as their Pro version of the D3 OEM with additional display support.

SpectraCal C6 – What we have build by X-Rite for us. Has different firmware, exposure modes and more capability for additional display types including field updates. It is also the most expensive for these features.

My C6 did not include a NIST cert of accuracy. Should it have?

Yes a C6 should have had a NIST cert in packed the carrying case. With a C6 you get a very nice sealed carrying case, tripod extender, NIST cert. But I know we had with the meter trade in program a limited version of the C6 that was just the C6 to save costs to the end user.

Derek,

I got my C6 as part of the trade-in. No carrying case, tripod extender, or the NIST certification. Should they have been included? The tripod extender is the most important of the three.

I still don´t understand what angle the sensor should be in towards the screen

If I screw it on a tripod should the cable from the meter be at:
The top?
The bottom?
The left?
The right?

Unless the answer is "top" then it will be different when calibrating my plasma since it then hangs from the counterweight making the cable being at the top.

So when describing "horizontal" or "vertical" a picture would help.

This picture means the cable is "to the left" :
