I was just looking into the Myiro-1 to see if it performs better than the i1pro. I found this:

Lighting measurements are captured at 5 nm resolution which is one of the ISO-3664 requirements not supported by i1 Pro.

Is this the case or is there am I misinterpreting the specs? If used with Colourspace on a monitor, is it more useful than the i1pro which doesn't really work for most modern monitors?

That is really a question for Myiro-1/Minolta.
Only the manufacturer will know the correct answer.

I have spoken to Myiro-1.
It is the reporting that is 5nm resolution.
The measurement resolution is the stated 10nm, although they said is is actually 9nm.
But, they also said the spectral accuracy is better than 'alternatives' especially in blue.

Thanks, Steve. It looks like this might be a good option for the LG WOLEDs as they don't look particularly spikey.

You don't need to focus on the measurement resolution, because the interpolation algorithm exists and can output results at virtually any resolution. FWHM is the point

In this case, FWHM is what is used to define the 'measurement' resolution.

Hi Steve，
Do you mean that the FWHM of Myro-1 is 5nm? That means the resolution of MYIRO-1 would be about 1nm, which is impossible.
For example, the FWHM of PR-655 is 8nm and the resolution is 3.14nm;
The FWHM of CS2000 is 4.5nm and the resolution is 0.9nm.
SR-3A has a FWHM of 5nm and a resolution of 1nm
In my experience, MYIRO-1 does not reach the sampling accuracy of the above spectrometers.

No - as above, it is 10nm (9nm potentially).
