Considering that they can achieve very dark black levels, what spectroradiometers are preferred by professionals to measure the panel accurately and get the job done?

What's the most accurate tool on the market today? The PR-680L SpectraDuo?

Though there might be *a* ISF with a PR-680 out there, I have never heard of one.

There are lab reference units better than the PR-680 - you just will not be carrying them into the field.

There are several units used by ISFers that will go down to the 0.2/0.3 level with x/y accuracy out to around 0.002/0.0015 which essentially are all about the same, as they are not tested on the same sphere, as well as some quote there line at that while others test individual units to that.

Bottom line, your eyes will never see the difference between 0.002 and 0.003 at 0.2fL or 0.3fL on a Pioneer Kuro.

Then what might be considered the best which a calibrator would likely carry into the field?

Also, how much do some of these spectroradiometers cost? I know the i1 Pro is a popular tool for DIYers, but also some professionals use it given it's cheap cost.

Do the prices rise exponentially for subtle increases in accuracy between different hardware?

There is an issue much more important about the current generation of Kuros than the instrument the calibrator uses. The non-Elites are really not candidates for calibration at all. Pioneer has apparently removed access to the white balance controls. All one can do (without an external device such as the Lumagen) is adjust user-level controls.

In no particular order, Minolta, PhotoResearch and ProgressLabs. Also be aware that most of the Minolta unit people talk about or ISFers carry is not the much more expensive CS-2000 Spectroradiometers.

Again, the key is not the best of the best equipment (if you had to choose between the above). Getting into a pissing match between 0.2fL and 0.3fL or 0.002 or 0.0015 accuracy is lunacy.

Its about the person that has done plenty of calibrations and has experience on how to best use the equipment.

Taking a wild stab from what ISFers have mentioned, I would guess there are about a half dozen PhotoResearch Spectroradiometers in use by ISF Calibrators in the USA, a half dozen ProgressLabs Spectroradiometers in use and no Minolta CS2000 Spectroradiometers in use by ISF calibrators.

Most used among calibrators will be the Sencore CP5000/CP6000 (whose day have come and gone), Sencore/Hubble OTC-1000, i1Pro and few will have the Minolta CS200 Chromameter.

The non-Elites are really not candidates for calibration at all. Pioneer has apparently removed access to the white balance controls. All one can do (without an external device such as the Lumagen) is adjust user-level controls.False. They have restricted access to the SM per the owner's remote (Left, Up, Left, Right sequence). However, all controls are still there and the 9G non-Elites grayscale can be fully calibrated...just like the 8Gs).

False. They have restricted access to the SM per the owner's remote (Left, Up, Left, Right sequence). However, all controls are still there and the 9G non-Elites grayscale can be fully calibrated...just like the 8Gs).There is no difference between this generation and the previous in this regard? That's not what ISF folks are being told.

There is no difference between this generation and the previous in this regard?The difference is you cannot access the SM with the old owner's remote code. You have to use RS232C commands or find a Factory PDP remote. The other difference is you have to "save" the work you have done in the SM (i.e. calibrating movie mode). So, yes there are access differences. However the calibration controls are identical to last year's models :)

Pioneer is a little ticked that their 'lockdown" initiative has been crushed. But, they will be ok :D

I'd like to share this with the ISF community, because as of now we are being told that calibration on these is not possible.

OK - there's no access to the Service Menu where grayscale adjustments are available using the remote that ships with the 5020/6020? Is this correct?

And chances of a calibrator snagging a factory remote are slim.

So that leaves the serial port method as the only viable calibration method... yes?

Now, you need functional software to access calibration settings via the serial port. Where is this available? Does the 8G Serial Port utility (released by a 3rd party that sells calibration hardware and sw) work or is a new serial port utility needed for the 5020/6020? If a new utility is needed and if it has not been released, then the 5020/6020 can't be calibrated until a serial port utility that is compatible with them is released. If the 8G serial port utility works, does that mean the 5020/6020 support 10-point grayscale adjustment (since that's what is in the 8G utility)?

Do you have any more specific info about this? Model # of the Factory remote?[QUOTE]I don't have the model number on hand. When I find it, I'll be more than happy to provide it to you.

[QUOTE]Procedures for the RS-232 approach?I think you already know what you need ;)

OK - there's no access to the Service Menu where grayscale adjustments are available using the remote that ships with the 5020/6020? Is this correct?No access to "turn on" that menu with the owners remote. However, the owner's remote works the same way it did on previous gens once you get in.

And chances of a calibrator snagging a factory remote are slim.Probably.

So that leaves the serial port method as the only viable calibration method... yes?To access it, yes.

Now, you need functional software to access calibration settings via the serial port. Where is this available?ControlCAL will be providing a display profile in the very near future to any and everyone.

Does the 8G Serial Port utility (released by a 3rd party that sells calibration hardware and sw) work or is a new serial port utility needed for the 5020/6020?No.

If a new utility is needed and if it has not been released, then the 5020/6020 can't be calibrated until a serial port utility that is compatible with them is released.The utlity already exists. It just has not been release to the public.

ControlCAL will be providing a display profile in the very near future to any and everyone.



I will buy a 5020 next week *if* I can calibrate the gray-scale.
Does ControlCal support sending the serial codes to get the display to calibrate and save settings?

I want to keep the budget down, do you have a recommendation for a meter. I was considering the deal with the Gamma5 or the Display LT?

Thanks,


Rich

RichI think that it is safe to say that there are at least 100 xx20 series owners who have had there sets calibrated per ControlCAL (at least 100 that I know of :))

As far as meters, the cheapest meter I would recommend would be the Chroma5....next would be the i1pro.

Hmm. Those are bit pricey.
I might get my feet wet with an LT if it can be made to work.
