For what it is worth---I have loaded in Manni's third attempt and Jeffy's new settings and compared them as objectively as I can by eye, to the THX CMS setup (I have no metering capability). I want to report my findings and have a question on the logic and validity of my conclusion that some of these settings look like they may be transferable to my projector with excellent results.
What I find is that that low saturation/lighter looking blues on Jeffy's settings match THX almost exactly, but Manni's are very clearly darker/or more saturated in appearance. Using THX as a reference, this is the only clear subjective difference I can see viewing many real world reference Video and Film segments I use for such judgments .
I also have been using 2 other objective ways to judge the color accuracy which may -or may not be valid:
1. First it seems to me that if the Color settings in the CMS are calibrated properly that the old standby filter method of setting the Color and Tint controls using the VDE BD disk should ideally yield Tint and Color control settings of exactly zero. Deviations here would indicate that the color CMS performance is not spot on (I am making the assumption that the Color Decoder in the RS20 is accurate). (I should note here that I found the THX mode unexpectedly required a color setting of 5 to satisfy this criteria. All comparisons below were made with this THX setting).
2. Secondly, after the Color and tint controls have been properly set, if Color filters are used with the VDE basics BD test disk to view the color bar pattern for testing color decoder errors.. then the R,G and B color decoders should look perfect (example... all of the primary and secondary colors and white viewed through the red filter should have the same red intensity).
Now I realize that many other criteria for excellent performance of the CMS setting exist ... but it seems to me that these 2 criteria above represent necessary but not sufficient
conditions for a properly functioning CMS.
That said I found all of the CMS work around settings developed on the original Calibration site did not
meet the 2 criteria above (even though they produced very reasonable -good looking images and helped us get through the "broken CMS era.) Since the CMS was defective this could be expected.
But now with the new version of the CMS firmware - and with simply copying in settings arrived at by Calibrations performed on projectors other than mine -I find that the CMS performance now unexpectedly comes extremely close to satisfying the above two "necessary" criteria.
Specifically, I found that Jeffy's new CMS settings produce almost perfect Color decoding while simultaneously satisfying the Color /Tint controls setting of 0. In other words Jeffy's settings seem to satisfy both of my Necessary conditions (and as discussed above - the less saturated blues match the THX blues perfectly).
I found Manni's 3rd attemt produces near perfect Color decoder behavior- but only if I set the Color control at +10 (Tint is fine at 0). And as mentioned above less saturated blues do not match the THX blues) So, at least on my projector, this case comes close to satisfying the 2 necessary conditions.
So my question is this.. do these results indicate a high probability that Jeffy's settings installed on my projector, results in a reasonable CMS setup?
If checked with, lets say, Jeffy's Calibration meter and software, would he end up with a pretty good Calibration report..or is it simply not the case that the 2 criteria I have set out are sufficient to allow drawing such a conclusion?
Thoughts on this would be appreciated.
And many thanks to Manni and Jeffy for contribution of their new settings.
