Hi zoyd, I've been having trouble figuring out if I'm getting proper readings from my i1d3 combined with my Panasonic GT25 plasma. I don't have access to a spectrometer so I've been relying on matrix offsets I've found online. Here's what I've been working with, at least until I saw the one you posted this morning:
1.0383 -0.015199 -0.012862
0.030022 0.96707 -0.0048218
-0.00042114 0.0066268 0.95594

If you plan on using the i1D3 with HCFR, you can download correction tables here. This will not provide you with the same level of accuracy as the tables Chromapure gives you with the i1D3 Pro, because the tables Chromapure gives you are for your specific meter. Just like displays, meters have unit-to-unit variations too, although the i1D3 meters have fairly small unit-to-unit variations.
To use a correction table from the link above, once you find a correction table, don't click on the download icon, click on the name of the correction table. It will lead you to a page with a bunch of text and numbers. At the bottom, there are sets of numbers.... these are the offsets/corrections. For example, here is one for a Panasonic plasma (in fact, the one I used for my ST50):
1.0383 -0.015199 -0.012862
0.030022 0.96707 -4.8218e-003 (or -0.0048218)
-4.2114e-004 (or -0.00042114) 6.6268e-003 (or 0.0066268) 0.95594
You have to enter these numbers in the sensor matrix tab in HCFR. You can also save the file so you don't have to keep manually entering this in. To do this, start a new calibration file in HCFR, enter the sensor matrix offsets in the initial setup; once the setup is complete, go to Advanced -> meter correction file -> save meter correction file. It will save a .thc file in which you need to place it in the X:\Program Files\HCFR Calibration\Etalon_Argyll folder so that when you start another calibration, you can select it from the dropdown box of the initial setup when it asks if you want to use a correction matrix.
The latest versions of HCFR can be found here. There have been some significant changes from the original version. zoyd added everything John was working on, and he also added his own things. If you have any questions, pm member zoyd, or post it in the Fork HCFR thread at AVS in the Display Calibration forum.
Again, HCFR is a very capable program if you know what you're doing, but it isn't nearly as user friendly as the pay software.
rahzel say's they came from a Panasonic Plasma here: http://dispcalgui.hoech.net/colorimetercorrections/
but I can't seem to find them there to verify.
Now I've noticed they're quite different from yours, could it be Samsung vs Panasonic plasma differences?
You mention using the Plasma Display Type, I had been setting it to "Refresh" display and entering the matrix values. What's the difference? Should I re-do the calibration?
Thank you, I really appreciate you keeping HCFR going.
Edit: One more question.. is MadVR TPG effected by the MadVR color range setting? (0-255 vs 16-235)
