The data saves to the Lumagen automatically at the end of the auto-cal routine. It saves to whatever configuration is active.
To reload the grayscale, you would need Lumagen's configuration utility....

Yes, I would like to know this too. What is the actual difference in xy coordinates between what the i1Pro 2 reads for the white point and what the i1D3 reads.

Yes, it will.
I have been mistaken about when we will be ready for release a couple of times now, so I won't repeat the mistake. As soon as it is ready, I assume sometime this summer is the best I...

I have the EA9800.

I just ran a 125-point auto-cal and the starting value for 100% was 96.53 and the ending value was 95.52, which is a negligible difference. I see no problem with changing...

Yes, I have used this technique many times, especially on Samsungs. BTW, this has nothing to do with BT.1886 per se. It is a valid technique for any gamma target.

Michael:

Could you quantify the trouble you are seeing? I assume that you are referring to repeatability issues? All N. American plasmas should read fine with a sync of 60 (or 59.94). I recall...

It is fine with plasma. It shows none of the repeatability problems on plasmas that the JETI 1201 suffers from.

I don't understand the first question. APL is the average level for the entire screen, not just the background. I don't know what ARL stands for. In any case, the black backgrounds are 16. The APL...

Our calibration Blu-ray has this. So does Masicor's disc and I believe Ted's disc. Other discs have ColorChecker patterns, though the precise RGB values may be slightly different.

You would never have a 50 Hz input in N. America, so this identifies a 72 Hz refresh rate sometimes (but not always) for 24p sources, which makes sense.

BTW, Pure is the Picture mode and Off,...

Both plasmas and LG OLED's use 60 Hz in N. America, so this can simply be manually input.
