    I agree that post calibration check with material is what matters even with great reports, but it should NOT be this far off. In my opinion it is broken. Yes it can be calibrated out but why should you need to do this?

    There are a few calibrators that have figured out how to work around the CMS. I am going to fight the fight for the DYI calibrators. I have a case logged and the Panasonic field engineer is coming out on 7/1. I've already sent in my settings and calibration report so their engineers should be able to replicate results in their lab.

    It's not hard to figure out how to work around it. Older Panny plasmas like the V10 were the same way in panel brightness high, but this year is the first time they have been like this in panel brightness medium. Again, it's not new to this model; I've been aware of it and working around it when necessary since the V10.

    In panel brightness mid and high, the color is non linear with stimulus level. You calibrate it with the standard 75% stim and you'll get colors that look too hot. You measure it with 50% or 100% and you'll get different results. I'll have to experiment some more to confirm this, but there's a chance that some in between stim level like 60% might give results that line up with what we see in the pic.
    Are you sure it's stimulus level and not APL? I would be curious to know if using the small APL color patterns generated a better result.

    Hi All,

    The oversaturation is due to incorrect color decoding. This is not new to the Custom Mode for the Panny Viera consumer models. Unfortunately, the ISF ccc modes are attached to the Custom mode. CMS works very well, but decoding is clearly wrong, and this requires de-saturating color significantly. A setting of 40 on Color seems to yield the best results.

    Default 3rd Panel Full Calibration Report and Settings

    Folks, I was suppose to wait until July 1st for Panasonic's visit before calibrating, but I decided to go ahead and calibrate it anyhow and zero it out with ControlCal later. This is my third panel which did not have any of those moire patterns at extreme angles. This is the first panel I've calibrated with the new firmware. I also decided to try Warm 2, and low panel brightness for now. So far I am happy with the results, and I will say I am still seeing panel differences, so although I am posting my results and settings, please do not assume my settings will work well on your panel.

    You can take a look at my report, and then the final settings in the last column. I've kept the settings from the other 2 panels for historical purposes so folks can see how the Low Panel setting and Warm 2 settings affect the calibration and results.

    So far I prefer the look of this panel and calibration, have not done any fBR testing, and I do not feel this is over saturated thus far, but I'll report back later as I've had limited viewing thus far. Color decoding was a bit better on this panel which cut down on calibration time, but I will say I think the decoder is still broken as luminance/saturation/hue settings are very sensitive, with 1 affecting the other more than one would think is normal.

    I will go back and re-do this in mid panel brightness when the Accupel arrives and take some of the advice here from folks regarding color settings and compensating for over saturation. I feel the low panel setting is too dim for daytime viewing. I just ended up copying ISD Night/Custom settings to ISF Day mode, and changing panel brightness to "High" for now and will re-check it later as I am sure it's no longer accurate in Day mode.

    Gotchaa,

    Thanks for posting your results again. I'll give them a try on my set and then tweak from there if they are in the ballpark on my set.

    I also found that color had to be at about 40 with panel brightness on mid, which defies the measurements. But panel brightness low gives much more accurate color and does not need to be reduced. However, low gives very low light output, so I used it only in night mode.
    So Chad, do you calibrate the color to correct measurements and then dial down the color setting to 40 or set it at 40 and then use the CMS to correct the measurement? Also can you give us a small bit of info on some of the quirks you speak of and how to work around them?

    +1No two panels were the same for me, and low panel brightness will not work for daytime viewing. I found that luminance, saturation and hue controls are just too interactive...

    Calibrators using ControlCal v2, can you post your ControlCal settings? This will be a good way for us to compare panel differences and quickly check your recommended settings.

    Gotchaa,

    I plugged in your settings last night and they are the best so far. They are close to the THX CNET settings which I still prefer over yours. Your latest settings were a tad dimmer than CNET's and a bit under-saturated on my set, but a very good starting place. Thanks for posting them. I could easily see tweaking your settings on my set and getting a good useable picture.

    Most Professional Calibrators do not Post Settings. D-Nice does Post his Reference Settings and his will be posted soon. Kevin Miller will also post settings at TweakTV. Some Owners do Post their Professionally calibrated settings.

    Most Enthusiast / DIY Calibrators do Post their setting with their data / reports - this has been helping the small (yet growing) DIY group with their own calibrations for a long time and has helped to bring many to Calibration.

    Turbe just wanted to say thank you for the latest enhancement to ControlCal 2.0. The VT30 calibrations are calibrating even smoother now and it's easier to get the best results.

    I would love to personally thank you parents for the great Turbe!! Good job Mr. and Mrs. Turbe!!

    Gothcha, what are your 100% luminance readings at Contrast 70 panel drive on low? My panel is right around 55 for brightness. The serial number begins with LJ1144. My i1 Display LT is not giving me consistent results. Something moves and clunks inside of it. I plan to get one of the new i1 Display IIIs from Tom when they become available. I should have something more to contribute then. I have ControlCAL now, thanks Turbe.

    I am kind of new to calibrating. Mostly calibrated some sets for myself and family and since a couple of weeks own an European TX-P50VT30.

    Do I understand you right that I should starts with color at 40 (out of 60) and go from there into the CMS to get the best results? Thanks!

    I made one change this AM, I set color to 42 and Panel brightness to Mid and I actually prefer this now for day time viewing. I also looked at the ISF Night settings and I can't say I'd use it during the day it's way to dim as you noticed so I think I will reserve this for evening/dark room viewing...I also did another ISF Day calibration with mid panel brightness and Cool1 but am not happy with it...wide gamma differences...at this point I am waiting till I get the Accupel pattern generator as I am not liking what I see on AVS HD709 disc, I get different readings from the Gamma/Grayscale patterns for white, I did not think this should be the case but it is....my next calibration will be at 200 hrs..

    Thank you Turbe. I very sincerely mean every word. If it were not for ControlCal and your outstanding personal support we could not have completed as many panels as we have and not been able to do them with the results we achieved.

    World class software and service.

    Much thanks for your brilliant programming and support.

    @LeRoyk, I am in the MJ series different factory...it is really low which I would not recommend for anything other than complete dark room.

    cdm2= 36.87
    fL= 10.76

    I am getting a D3 as well so we can compare results
