Interesting.

Ted do you know when Jeti is talking about a external USB power supply, are they talking about a power hub. ?

I was playing with the 1211 today on my VT60. It seems that setting the refresh rate at 60Hz rather than 96Hz along with setting my Lumagen to out put video RGB BT 709 rather than 4:2:2 BT 709 stabilizes the Red readings. Yes I am using the auto sync for the 1211.

I will have to play some more to determine what works best with the VT60 and the 1211. I will also use Jeti advice on the settings for USB in my PC tomorrow.

Right now I am running a 21^3 profile. I profiled my K10-A with the 1211, setup my 100% grayscale setting in my VT60. The interesting thing for me was that I have always felt Red was off (to high) when setting my RGB in my VT60. Before I ran the 21^3 profile I set my 100% setting in my VT60, and yes it seems that when using the 1211 stand alone or the K10 profiled to the 1211 Red was being set to high when using my I1Pro 2 to profile my K10.

How does that compare to the 1201s you had?

Its not that the 1201 is a bad mete,r probably a very good meter. It can't sync with my VT60 or other Plasma's from what is said.

I need to play more with the 1211, but yes it seems to sync with my VT60.
As I thought Red was off the biggest, then Green and Magenta using my I1Pro 2 to profile the K10-A.

When running CM's QC every thing that has to do with the CMS (Color points, Lum, Sat) is tighter along with fine tuning the grayscale.
The little I have viewed a Blu Ray disc, there hasn't been anything that looks slightly off.

I can see when I am are setting my black level at 0% and 5% you still need the K10. Like the CS 650,850 and 2000 they are very slow reading low light, so the K10 is a very nice plus.
There is no way I could do a 21^3 profile/LUT using just the 1211 or any spectro only. So at the very least you would need a D3 to go along with the 1211.

I hope this was not just a fluke, so I will be able to tell more in a week or so.

It sounds like the i1d3 is faster than the 1211 at low light. Is that your take on it?

Hi SillySally,

I'm getting a bit nervous when reading Your post about the i1pro2, because I just ordered one to calibrate my VT60 along with the I1D3.
Could You say anything about how much the i1Pro2 is off compared to the Jeti?

thanks!!

My sold C6 (same as D3) was faster on low light.

Don't worry the I1pro 2 is a good spectro, just not reference. There are a lot of "pros" that use the I1Pro,

The picture was done by Klein, using there reference CS2000 spectro and my I1Pro 2

Thanks for the chart.
Do You know what was the light source, TV? It would be interesting to see this with a VT60.
As to the new red phosphor Panasonic is using I would expect the colors (red) will show different (smaller) bandwidth according to the VT50.
Couldn't this cause the issue with the i1pro2 on red?
Do You remember if the colors were off in the same way on the VT50 calibrated with i1pro2?

Can You please provide a chart like above using Your Jeti and i1po2 with the VT60?
Really would appreciate that.

Virtually any colorimeter will be more sensitive than any spectroradiometer. Tristimulus colorimeters have much larger photo-sensitive elements.

a reference spectro (with higher resolution) becomes more important for measuring the spectro of very wide gamut displays, because the wider the gamut, the narrower must be the RGB peaks, and so the higher resolution must have the spectrometer in order to measure accurately those peaks.

I think that if you compare the iPro vs CS2000 when measuring a Vango vpr (RGB LED), you'd see larger measurement differences.

interesting.
In my limited supply of meters, blue is the one color that changes the most from meter to meter.

Hi Ted,

Please explain why anyone would care about a 2 dE difference between the two readings and address the following:

1. 2 dE may be detectable in side by side still images but in moving images it will not be noticeable.
2. The measurement is at fully saturated blue which will hardly ever occur in typical material.

Hello Zoyd,

Any Meter Profiling Measurement Patch Sequence (Spectro -> Colorimeter) is using RGB 100% Saturated Color Patterns, so if you have a difference of 2dE there, this is translaTED to some milion shades blue that will be of by off by 2.0dE minimum.

You capitalize the letters "ted" whenever they occur in your posts. It just seems a bit... silly?

Ted,

Your point about being off 2dEs throughout a cube calibration when your profile at 100% would seem to not really matter when taken in isolation but I'd wager that other things may be going on that would add addition dEs such as plasma panel fatigue, meter drift, etc. when running a calibration that takes an hour and a half up to four hours with high end color meters.(too long a sentence smile.gif ) So it does make sense to get it as accurate as possible as other things will creep into the measurements.

With that said, traditional calibrations wouldn't have as much need since you have only a few measurement point and can pause your calibration and run screen wipes or full screen white patterns to clean up IR.

Since large cube calibrations do take a bit of time to perform, it wouldn't be a bad idea to add the feature where cube calibration periodically pauses while patterns display that would clean up IR and return the display to normal operating temperatures. Although this is mostly a plasma phenomenon, who really knows if OLED or any future tech wouldn't also benefit from this.

Nothing personal, but I think spacediver is right. Brother, it's time to leave it in the past.

Hello, If we include the fact that:

1) There is no standard in Gamma Value

2) You don't know if the displays are used for Blu-Mastering was accurate or how tight was calibrated.

3) What meters / software they used , are you using the same at home?

4) What was the enviroment light conditions during the mastering, do you have the same at home ?

5) What display types they used to verify the content.

6) What peak light output they used, what window patterns they used, did you used the same size or peak during your calibration?

7) What driftings they had to their monitors (since it was used for a lot of times continiously), and your own display drifting.

8) The fact that all displays/projectors are drifitng during the working time, while you see a movie 2-3 hours is operating.

9) Add the off angle problems or LED's, are you viewing from dead center?

10) Add the bad display screen uniformity of the consumer displays.

...after all the above seems like there is no need to try to get the best from your display.... put the movie mode , no calibrating, and all good...

But No, this is about image fidelity, using better tools and software you are getting closer.

Anyone with LightSpace who want to see the difference of 2dE to his setup, he can do the following:

Using a saved profiling file, generate 2 correction LUTs, one with REC709 targets and another one with modified REC709 targets, for example change one xy color cordinates to have 2.0 dE, and after load these LUT's to Lumagen or eeColor, swap the memories and see the difference.

Do you believe the is no visible difference if you use i1PRO or JETI 1211? since the dE difference numbers are low?

Maybe not the point but;

This dE of 2 shown compares a single i1pro to a single jeti 1211 on a single display.
Were the same two meters that were compared on the Kuro used, if so what is different about the Panasonic?
Were readings done back to back?
Is it just assumed that the 1211 is the reference? was it verified?
Is it possible that the 1211 was reading 1 dE low and the i1pro reading 1 dE high?
When was the i1pro last certified?
Can (has) a similar result been duplicated with a different pair of meters on a different panasonic of the same model?
Specifically what Panasonic plasma model?
And as zoyd already pointed out will the same difference between meters be present at a lesser saturation point?

No doubt in my mind what meter i think is better and which meter i would blindly trust more, but there are more questions than answers that come from this flashing chart.

Yes, same meters, some time, same place

Were readings done back to back?

Yes, BTW

Yes, JETI 1211 (11.000$) is reference for sure, it was brand new.

Is it possible that the 1211 was reading 1 dE low and the i1pro reading 1 dE high?

i1PRO was inside it's 1 year certification period.

I don't understand why you need this ? It's measurements, and JETI is 11 times more expensive meter than i1PRO, do you expect to have the same performance?

Specifically what Panasonic plasma model?

Panasonic ST60

And as zoyd already pointed out will the same difference between meters be present at a lesser saturation point?

Ask Zoyd to send you data for this, next month I will have JETI 1211 here with me and I will compare it with my i1PRO1 + 2

Hello, Check @ bold letters above is my reply.
