I don't think I need professional benchmark accuracy, I am just looking for a consistent result where any error would most likely not be visible. I may be upgrading my display next year and would like something that I could leverage auto-cal with or at a minimal make a really solid 10 point calibration. Seems like some folks have had alot of success with a D3 and a correction table for their display. How would the C3 compare accuracy wise to the I display pro ?
Thanks as always for both your support regarding Calman. and calibration in general
One thing that you have to understand is that spectrum of each display you test will have a large effect on the perceived accuracy of a meter.
I can show you an LCD that will make SpectraCal C6 look like it challenges a CS2000 for accuracy out doing even the Klien K10. I can also show you a display where it would be obvious that profiling the C6 against the i1Pro will provide a signifigant improvement. This even extends to spectrophotometers as how spikey the spectrum is, impacts the resolution you need to measure it (spectros range from 10nm to 1nm). So you need to look at perfomance over a wide range of displays to make any kind of blanket judgement.
Another thing to note, is since Micheal Chen's review of the C6 we added both a wide gamut white LED table as well as white LED RGBY LCD table to the C6, so if he were to run those tests again we would see much better results. On the technical side, if you are going to compare meter results head to head you also need to match field of view exactly. Something like the Jeti, which Micheal uses, has a very narrow field of view and the i1 Display Pro and C6 have a much wider field of view. Comparing results is only valid when you measure the exact same area with both meters, which is why our lab has an elaborate jig for calibrating meters. We can guarantee that the alignment is accurate every time.
So back to the meters, the C3 is based on the older chroma5, but it has 3 tables a CCFL LCD, white LED LCD table, and a plasma table, the i1D3 adds a UHP table for projectors and a CRT table. The D3 has lower light sensitivity, optics to provide more consistent measurements with out worring about angularity issues, the optics also allow it to do a much better job reading projectors, The sealed optics mean that meter is much less sensitive to drift, the few meters we've retested after over a year of use have had very little drift (less than 0.005x/y). That said 4 or 5 years ago the Chroma 5 was a $1000 meter and the go to colorimeter for most pro calibrators.
The last thing I would say, is if you look around the forums you'll see many examples of how accurate an aged i1 Display2 is, and it's not pretty, so what ever you do I'm sure you'll be happy with the results.
