The subcontrast controls are effectively multipliers.
Red is (50/50) * (130/128) * (95/100) * (128/128) = 0.96
0.96 is the only important number, any way you change the formula to end up with 0.96, you have 0.96 as your final contrast for red. If you turn one up, then you'll have to turn something else down. The end result will be exactly the same.
Everything else is just wasting your time.
AVIDHIKER: I don't know connector, from what you are now saying, the ADC system on your LCD is nothing like my plasma (or at least, a lot less like it - and I don't mean the different default values). The current generation plasmas have only ONE set of ADC/WB adjustments. These apply to ALL picture modes. The color tones (with the exception of dynamic) apply additional corrections to the ADC/WB values which cannot be changed (or even viewed) in the normal service menu. I can't really make heads or tails of what you're saying at this point and it's becoming tedious to decipher your posts.
agree with sotti (and have made the same statement to you and others) - there was never any hope in improving your picture quality/calibration by making changes in the service menu - especially when adjusting by eye and with very little understanding of how the system really functions. Punching in default values is not going to improve on factory settings. If you cannot recover the original factory settings, then I would suggest you just leave all values at their defaults per the service manual (that is what happened to me when Samsung replaced my main board).
WRT the gamma control, a setting of +1 typically results in a reduction in display gamma by 0.1 (on plasmas). I do not know what the default gamma is for your display.
HUNGRO: IConnector a decrease in the gamma preset from the default value of 0 results in an increase in the gamma for the samsung d series plasma .FYI Not knowing what your actual tv's gamma is at in the default position it's hard to say which setting you would be closer to 2.22. On my display a samsung d6500 plasma a gamma preset of 0 with all user menu values at factory for Movie Mode gives me an average gamma of 2.19 .
i'm trying to explain my best but even my english it's a bit limited , please excuse me if I created any confusion, I will try to answer each one as best as i can, i'll unify my response and my questions in only one post:
I will try to explain the steps I've done to see if I'm doing it right or I'm wrong so I can correct it with your help:
1) First i have donde an alingment with ADC RESULT with Zoyd's pattern disc (and with his help), using "sheckerboard" 16-255 with a result of subcontrast 132 and rgb 50,50,50. All fine here.
2) After the alingment with "successful", i leave the ADC WB with their optimum default values ONLY for DYNAMIC, NATURAL and STANDARD reported by my Official Samsung's Service Manual for my TV Model. That's because i can't touch nothing except subcontrast in MOVIE mode, so MOVIE mode contninues with their default values. The values are subcontrast 128 and rgb 512,512,512 (in LED TV my range is 0-1023 for RGB in PLASMA is 0 to 255, it's like you set in your plasma all to 128).
3) Take the AVS 709 Blu-Ray in my Samsung Blu-Ray player fixed to YCBCR. I check each pattern from "basics" section:
For Dynamic, Standard, Natural and Movie mode:
- Black clipping: making that bar number 17 continue flashing adjusting the brightness (to mantain a good black level).
- APL clipping: making that ALL the "white" bars flash and with the "black-grey" bars continue flahsing up to bar nº 19 (to mantain a good contrast and brigtness).
- White Clipping: making that ALL the "white" bars flashing (all flash up to 253 with no decoloration or pinking or clipping). Re-check Black clipping and APL clipping to view if there are changes or everything goes well.
- Color Bars: making with the blue filter in STANDARD and MOVIE modes that all the bars keeps flashing equals and adjusting Hue and Sat to do that. In MOVIE Mode the color is 48 with 52/48 and in STANDARD Mode the color is 32 with 48/52 (all dynamic contrast and "enhacements" disabled).
- Color Clipping: making that all the bars up to center number keeps flashning with no clipping in any color.
- After that i don't change in User Menu my WB balance because i don't have a meter and no i couldn't buy it.
The Questions after reading the steps that i have said please (becasue maybe i'm doing something wrong):
- Is it correct that method to make the better possible "callibration" without a meter (knowing that is not perfect but is better than do nothing)?
- It will be preserve in MOVIE mode the "nearest to D65"?
- If i change the user menu Gamma to something >0 in movie mode, am i get very far from Gamma 2.2?
Thank you very much Sotti, AvidHiker and Hungro for your attention and patience, i'm waiting for your responses. And again sorry for the confusion that i could have created.
