I am just getting familiar with CalMAN, ControlCAL and ISFccc. Rather than reinvent the wheel, I activated ISF Day/Night and used D-Nice's recommended settings. As you can see, I'm having a problem with Green grayscale tracking. Should I be reducing RGB Green High and Low?
How do my color points look? Any recommendations for improving?
Also, I few things I don't understand about the ISFccc interface: What does Y-delay do? Should I-P Mode be on 1? What about Enhancer Mode? And I notice that the screen size mode doesn't seem stick when saving in ISF Day/Night. I still have to manually switch between Full and Dot-by-Dot. I was hoping every time I go to ISF Day I'd be in Full, and ISF Night stays on Dot By Dot.

You shouldn't touch the green high or lows. Green is used as the reference to calibrate the other two colors. Increase your Blue and Red which will make green come down. Leave Y-Delay and I-P mode at defaults.

Of course after increasing blue and red make sure you're not clipping any of those primaries and if so then simply decrease contrast ratio until you're not clipping anymore.
Right now in ISF Day you're right around 42 ftl so you should be fine increasing red/blue without any clipping.

Thanks guys.
So, increase my RGB Blue and Red (both High and Low?) a few clicks positive until it starts tracking better?
How do I go about generating that entire calibration PDF report (like I see D-Nice use)?
What about my CIE Gamut? Reports from D-Nice look a bit more accurate. I understand I shouldn't be pushing the CMS primaries/secondaries more than +/-2, so I'm not sure if I will do more harm than good.

Ok maybe your right about green in a perfect world , however in the settings he didn't use green. And to bring green down as much as it needs to come down or to get into line what is going to happen to the rest of the settings. As you can see in the Gamut green is way off as it is in any 9G kuro that I have seen. And if you try to bring green and the rest of the primaries in line you are going to through everything way off. What so far i have seen is that changing the primaries In CMS for your gamut is the kiss of death so there is no help there.

I am sure you are right, that will help. But imo and please understand that the only 9G Kuro I have worked on is the 141, It still is going to be off. Like I said the only way I have found to get the RGB tracking and grayscale right is to use Green high and low. And also when I use G H/L my gamma comes out like a lumberman's dream, flat as a board.
So beside just using R and B H/L what other controls would help.
btw, it looks like you were right on the money about break-in.;)

Thanks for all the good tips guys, keep 'em coming.
OK, here goes round 2 with ISF Night. Better grayscale tracking, but I think my CIE Gamut is more off. I realize it is a trade off, I did quite a bit of back and forth. Why is my "Grayscale Scatter" graph worse? Also what is the RGB color balance bar graph telling me? Where is green? Too for off?
Here are my new settings:
RGB Controls
R High -1
G High -5
B High +4
R Low -1
G Low 1
B Low -1
Your colors are screwed up because you have G-High at -5!!!! The Green channel is luminance. You should not play with green unless it is absolutely required. If you do come to the conclusion that you need to touch the Green channel (both high and low) only move it by one click.
I high recommend you recalibrate and only use the R and B grayscale controls.

How many hours do you have on your panel? If it is over 150 hours, you may just have an oddball panel. Green in CS2 should not be that far off, but it's not the end of the world if it is. I would focus more on getting your grayscale correct and correcting your secondaries.

I'm sure I have at least 400 hours on it. I followed your break in procedure explicitly, for 150 hours straight.
Could it be a problem with my meter? I have measured at least 3 other TVs with my meter, and all show a similar amount of Green deviation.

Yes, my powersave is off, and I'm not using room light sensor.
Based on what you've seen from my graphs, would you recommend going back to my first posted settings, and try to bring up R High and B High just a bit to tame the plus green?
Also, I'm going to ask the dumbest question you've ever seen on this forum: Based on how I have been observing my adjustments, RGB Drive controls (High) have the greatest effect on the higher IRE settings (i.e. 50IRE +) and RGB Cuts (Low) have a greater effect on < 50IRE low end grayscale?

LebEryo, thank you for the tip. I tried increasing R-Low to +1, but it knocks it all out of whack. 20 IRE becomes visibly red, and it measures poorly too. These controls are very sensitive, almost too sensitive!
D-Nice, what about the plus green on my August set? Can you expand on what you heard back from Pioneer? I think the folks at AVS should be aware of this.
Also, it is definitely not my meter throwing off the Green primary. Last night, for fun, I threw the meter up on a little 15" 4:3 LCD back from 2002. Yes, it is that old, and that small. One of the first consumer LCD TVs ever. The brand is Luce, and it cost a ton. To my surprise, grayscale measured better than my Kuro, and Primaries and Secondaries were spot on. It is kinda ridiculous actually. This TV has virtually no picture controls, and measures perfect out of the box. I always knew it looked good, but this blew me away. I can post a chart later if anyone wants to see.

At any rate, there are two locations making 60" glass. One production facitly does 50 and 60" glass, the other only 60". The plus green 60" models are coming from the 60" only production facility. There is no real way to distiguish between the two lines. There are some 60" panels that do not have the plus green grayscale (I've calibrated 2 of them). However, the majority of the 60" panels, so far, are plus green.

As a reference I also have an HHPM 60" panel and it also has plus green. My final grayscale measurements ended up being RH+3, GH0, BH+5, RL-1, GL0, BL0. For ISF Day with Contrast at about 32 I believe.
My ISF night settings were a little different, I set contrast at 23, RH +4, GH0, BH+5, RL-1, GL0, BL0.
My grayscale ended up looking pretty good. I'm going to measure again tonight possibly and post it on my thread. The only thing that's kind of bothering me is the green being off, like yours in the CIE chart. I don't think there's a way to fix that though.
BTW. If you see RL throw off the 50-100IRE measurements, you might be able to just lower RH by one tick or so and it would probably fix it.

Your ISF Day is very close to mine. I spent a combined total of 3 hours trying to get grayscale right. RL was more throwing off my low IRE, I think I tried every combination possible. I had several of those "what the hell am I doing fooling with this 2 hours later?" moments :)

You have it backwards. You were suppose to place G-High at -1 and G-Low to +1 :) That was only suppose to be your baseline for the calibration of which you would then use the RB High/Low controls to fix the grayscale. If you the the G-High and Low channels as I recommended it should fix your luminance issue :)

I did GH at -1 and GL at +1. I posted my settings and comment incorrectly, as it was late and I had been staring at grayscale windows and 75% colors for a few hours too many :D
Your recommendation evened out green, but I still needed plenty of boosting BH and BL to bring it down across the board.
I know it looks like there is too much Blue at the low end. However, if I drop it by one notch, it takes it to around ~95, and pulls green up with it. The Blue Low adjustment is too coarse.
I worked on it for several hours. What you see really is the best I could get (and I'm getting much better at it now ;) ). I am still eager to learn about how I can fix my Luminance, and help out my Green CIE.

Ok how about this....
Forget using the CMS controls for now. Set your G-High to -2 and keep G-Low at +1 and see how flat you can get the grayscale with only the R-High, B-High and R-Low controls. I would recommend keeping B-Low at 0 but if you have to use it, only move it to +1.

OK, I nailed grayscale! Per D-Nice's suggestion, I zero'd out CMS controls and grayscale controls. All CMS settings are zero, grayscale controls are as below:
Red H 0
Green H -1
Blue H +6
Red L -1
Green L 0
Blue L 0
So, just minor tweaking ended up with my best grayscale yet. And my CIE gamut really looks the same as before. It is now obvious to me that any CMS adjustments really mess with grayscale. I still don't know how to move Green on the CIE, or why I still have the luminance hump. Just how visible are each of these going to be with real world viewing?

Congrats :) You still need to fix that luminance curve. It looks as if the only way you are going to do it is by reducing the G-High to -2 and placing the G-Low to +1. Hopefully that will not harm your VERY GOOD grayscale :D

I'm afraid that's a no-go. I made those two adjustments, and everything got all out of whack. And luminance didn't even improve :confused:
Image removed, it was a poor reading.
I'm happy with grayscale, but still bummed about my Green CIE. However, subjective watching yields a very satisfying picture in all regards.

Yes I also use 2.2. Try power mode for gamma, click off Gamma correction and I use 1994 for my formula. Remember one thing, and that is how do you like what your display looks like. Yes the numbers and graphs look nice on paper and are a good guide, but if you do not like your picture on your TV what good is it to have a great looking calibration on paper?
And one thing is for sure, that adding controlcal to your calibration software is a nice plus.
Keep playing with your settings, and I am sure you will come up with settings that you really enjoy.

After 7-8 months, I decided to take another look at my grayscale today. Blue shifted down quite a bit across the IRE range as my set aged. Here are my old settings:
Red H 0
Green H -1

Red L -1
Green L 0
Blue L 0
New settings (changes in bold)
Red H 0

Sorry I didn't take a screen grab, but everything was really flat from >20IRE. All my CMS points are set to 0, Color = 2. I notice Color control does not effect grayscale, but Contrast does a bit. The settings above are for ISF Day, with Contrast at 30. Below are my settings for ISF Night, Contrast at 22:
Red H 0
Green H -1
Blue H +10
Red L -1
Green L 0
Blue L 0

So, 14 months later, I took a measurement of my grayscale. Wow, had it drifted! I'm also attaching settings I used to get it back tracking practically perfect.

SamS,
I believe you use a Chroma 5. My advice is if you could borrow a spectro as the drift that much might have been the meter instead of the panel...

Yes, I have the Chroma 5. It would be unlikely I would be able to borrow a Spectro (not familiar with that one, can you provide a link?), but maybe I should sent my Chroma 5 back for a re-calibration?
I realize you're not supposed to judge via eyeball, but when I added red to grayscale, gray windows didn't look too red. In other words, the adjustments that I performed via the the meter didn't look too off from a visual standpoint.

Sam,
The EyeOne Pro or the ColorMunki that Spectracal has will be pretty good for that. At the moment, I am not sure you want to send the Chroma5 for recal as there seems to be some issues with the C5Es with the Pio plasmas.
If u could borrow one, u can verify if the Chroma5 has drifted. Of course, profiling the C5 to the EyeOne/ColorMunki would be ideal I guess.
Its just that I have a hard time believe that it drifted so much.

Interesting. I can't really find a price for the EyeOne Pro, but maybe I will invest in that eventually, if it is not too much.
Regarding the drift, I was surprised too. My set does not get a lot of use, sometimes less than 5 hours a week. It is not my display for casual viewing. Because the drift was so linear, I just figured it was normal for aging. I guess it still could be?

Apologies for bumping such an old thread, but I was hoping you (or anyone else) could expand on this comment.
I'm considering getting my Chroma5 recalibrated or upgraded to the PRO version. What issues are there with this meter and Pioneer plasmas?
I'm also going to calibrate a new Samsung CCFL LCD I got for the bedroom. I did another Samsung CCFL LCD for the living room, and it turned out fantastic.
