In these screen shots you show the corrections for the i1D3 are enabled, but for the CR-100 they are disabled. You are correcting only one of the meters with the CR-250.

This is not a hardware error. Regardless of the hardware you are using, if you correct two meters with the same reference and then measure the same display it should measure the same. This is a...

Yes, it is. Often the CR-100's sync detection reads a multiple of 60, which is harmless.

Y is luminance, which can be represented in a variety of ways. You are referring to one of those ways only--absolute luminance. This is raw numeric value (in fL or cd/m2). ChromaPure shows the target...

It is supported by ChromaPure Professional and ChromaPure Plus. If you have ChromaPure Standard the only external generators supported are the DVDO Duo and Lumagen Radiance.

Sony has been coy about exactly what they are doing with the B series (the A series was quantum dot), so I really can't answer your question. BTW, how you you know that it reads red incorrectly at...

I don't think it is out of the realm of possibility either. A true quantum dot display may or may not have this problem. I don't think it is impossible, just rare. I still await xy data on this.

No, I'm sorry, you didn't. Neither the i1Pro nor the i1D3 are reference instruments. All you may be seeing here are differences between the two instruments. That's why a reference instrument is...

Without. I am not interested in the accuracy of the correction. Just use the meter's native mode.

Really? How do you think the i1Pro converts spectral data into colorimetric data? That's what the SO functions do.

v. 3 Update

I had hoped to get ChromaPure 3 out by the end of this month. I am now pretty sure that this is not going to happen. I think that our release date is going to slip 4-6 weeks.

Now that I think more about it, matching to a D65 white balance card--rather than what your meter recommended--doesn't speak to the issue either. The reason is that if the card is any good, then it...

While matching to a known visual reference speaks to this issue, the perceived differences between the i1Pro and the i1D3 do not. The i1Pro relies on the 1931 standard observer.

Displays with a wide gamut are nothing new. The JVC RS1 projector--now nearly 10 years old--was famous for having a super-wide gamut (close to DCI-P3). RS1 owners were a large source of customers for...
