Even if you bought a new one every couple of years, it would be more than 10 years before you had invested as much money as you did in the single i1Pro.
BTW, I just noticed that the passage you cited has a typo. I meant to say "Both the Display 2 and the Chroma 5 are reasonably accurate for luminance down to below 0.05 cd/m2."
Would you suggest setting up the Display 2/i1 Pro offset in Chromapure with the 100% or 75% window patterns? The reason I ask is I used the 75% patterns from the AVS disc and have the following charts. Chart 1 is from the Display 2 as the field meter referencing the i1 Pro. Chart 2 is the i1 Pro alone. One can clearly see the low light ability of the Display 2 over the i1 Pro. Do these results look as expected?
I keep playing with the calibration on my G10, but do not think I am going to get it any better. I keep calibrating the gray scale in Custom, then THX just to do it. I need to find some people with local TV's that need tweaking!
Lastly, is there a way to "export" the charts like you can the images with Chromapure? I find the cleanliness of the x,y,Y,DE,CCT,Gamma gray scale values or x,y,Y,DE color values from wtihin the program more desirable to post than an excel .csv file. Maybe add the ablitily to export these as jpgs? Just some food for thought...
