Hi David,
pretty simple: max. luminance in cd/sqm divided by min. luminance.
You can see that black has an extreme influence on the contrast ratio.
Since our desktop instruments are least accurate in the dark area, I
wouldn´t attach too much importance to this contrast ratio numbers.
Best regards,
Karl Koch

still cannot figure how the 0.26 is found, arrived at, or displayed
on the graph. I am going in circles. As well, as nearly ready to
give up.

Is there a tutorial regarding where to find the 0.26 value?
Can you please point it out to me?
Just when I thought I knew it all! (humor, don't cha know)
In that screen capture, you have 100:1 contrast ratio (70 divided
by 0.7). IF you calibrated to say 90cd/m2, and assuming as I would
expect, the black would be the same, the contrast ratio would be 128.
