Thanks and sorry again for the OT question.
For my ST60, the i1D3 read red a little low, blue a little high compared to the Munki, and it was a pretty steady difference, with red about -1% and blue about +3%. Running each against the same TV settings, the Calman grayscale results (dE Avg, dE Max) were i1D3 (1.29, 1.66) and Munki (1.04, 1.48). (NB: These results and the ones to follow are before tightening up the calibrations; for example, for the ST60, I ended up with (.4, .69) for the profiled i1D3.)
There was a greater difference for my HP Z24i LED monitor. Again the i1D3 read red low and blue high, but the discrepancies increased across the grayscale, reaching about -5% for red and +5% for blue at 100% white. The i1D3 dEs were (1.72, 2.61), and the Munki was (.42, 1).
For my CCFL Sony KDL-EX500, the i1D3 read red high
and blue even higher compared to the Munki, with the i1D3 up about +2.5% for red and +5% for blue. The i1D3 dEs were (.97, 2.08), while the Munki dEs were (2.7, 3.9).
Was the Munki worth the $60 rental? I would say yes, but the differences for me weren't huge, and they were larger for the LCDs than the plasma. Of course, without reference level equipment and procedures, I have no way to assess just how accurate the results are, but I am very, very happy with the ST60 picture at this point and the other two displays as well. FWIW, I recently wrote down my ST60 procedures and results here:
I'm copying the results here, which I think are interesting in light of all the talk about processors and LUTs:
10 point grayscale (.4, .69)
21 point grayscale (.47, 1.53)
25% 10 point Saturation Sweep (.61, 1.48)
50% 10 point Saturation Sweep (.61, 1.4)
75% 10 point Saturation Sweep (.59, 1.89)
100% 10 point Saturation Sweep (.95, 2.69)
ColorChecker (.69, 1.94)
ColorChecker Full, the one with a gazillion points (.81, 2.23)
It's not thousands of points, just hundreds, but the maximum dEs are all below the magic number 3, with the averages below 1.
