Hi all,

Ok, I am a complete novice when it comes to calibration but am very interested in getting my 6010 as close as possible to spec. Using the AVSHD 709 disc and the Chroma 5, I used the offsets for RGB to get my white balance to 6503. Now when checking my gamma reading, the Luminance seems to be on the high side while my average gamma is lower than the desired 2.5. Here is the link to the chart. http://home.comcast.net/~vipergts01/gamma.pdf
Every time I try and bring the gamma up using the RGB cut and gain controls it throws off my white balance. Since this set is not an Elite, is it possible to even be able to get gamma to 2.5 without losing my white balance? I also had a difficult time at around 30% gray hitting my target area {using Calman}.Seems no matter how much I lower the B-low it still has too much gain. Hope these questions make sense. Any help would be greatly appreciated!
Thanks

You don't adjust the gamma with the RGB controls. You need to play with the "Gamma" control in your user menu ...although the 6010FD is not capable of achieving a 2.5 gamma anyway.

Thanks D-nice. I didnt think you used RGB for Gamma because Calman is pretty precise on explaining adjustments. Only reason I even tried is because no matter which setting I used in the user control I couldnt get 2.5. Now I know why. So basically other than white balance, is there anything else this is set is capable of calibrating? Again, I am a little embarrased at my lack of knowledge but after reading thru most of the threads I still havent gotten a clear understanding. Thanks again.

User controls and grayscale. That is about it. Everything else falls where it falls.

Unfortunately, if you aspire for better performance, you bought the wrong TV. :(

Phil,

Firstly, your 0% Y is twice your 10% Y. That is obviously wrong. Best to edit the 0% readings and set them to 0.

Your average Gamma is 1.99 so it aint too bad. I follow Tom Huffman's guide (http://www.avsforum.com/avs-vb/showthread.php?t=852536) and shoot for 2.2. The formula is 100% Y * 0.0065 = 10% Y. So lower your contrast or increase your brightness to get it close to 2.2.

The lower stimlus readings can be tricky. Just go slow with the readings and let the meter stablize with several readings before adjusting the RGB controls.

Good Luck!

Contrast too high. You're getting runout over 90IRE. Drop contrast and see what it get's you. Of course you'll also have to tweak brightness once contrast is set. Also, no need to calculate 10 IRE Y yourself. Your calman chart shows you what the luminance (Y) should be. Once you have contrast at an acceptable level (where there is no runout), then adjust your brightness control using a 10IRE window to what calman says it should be. Will get you close.

Firstly, your 0% Y is twice your 10% Y. That is obviously wrong. Best to edit the 0% readings and set them to 0.

It's a bug in our data grid view the 0% is 1.6717e-4 but the exponent got trimmed off. In decimal it would be 0.00016717 so for all purposes 0 because it well below what most meters can measure.

On my two 6010s, the Lows (R-Low, B-Low, G-Low) don't do anything and I leave them at the default of 512. Only the highs have an affect.

Everyone's advice of using Contrast and the menu gamma control is correct.

I have not had the pleasure of using CalMan, only HCFR, but I have experienced run to run dramatic gamma shifts and tend to believe it is affected in HCFR by the brightness setting affecting the gamma calculation. Too bright and you get a low gamma, too low and you get a 2.5 gamma. For me, trick is to get contrast and brightness just right to yield the correct gamma and still have a proper white balance.

My biggest problem with grey scale is that on both my 6010s, blue tends to go up dramatically below 30%. I can get red and green to track well, but low end blue is a problem. I sure wish I could get B-LOW to work.

Hi,
First of all, thanks very much for the help!!! I went back and redid my Gamma using the contrast and brightness besides tweaking the RGB again. I dont think I can get it closer to 2.5 than this. Here is the link for the new settings. http://home.comcast.net/~vipergts01/gamma2.pdf
Now, Besides doing an eyeball setting with the color pattern and blue filter, is there a more acurate way to adjust the saturation with only the "Color" control? I havent quite figured out the best way to adjust my colors using only the one setting with the meter yet, so any tips would be greatly appreciated. Btw, Voyager, I actually got some results using the low RGB, but I do agree that no matter what it seems B low is very dominant in the lower scale.

Put up a 75IRE white window and take a measurment and make note of your luminance (Y). Then throw up 75 IRE red window and take continuous measurements and adjust the color control until Red Luminance (Y) is 21.27% of white (for HD - REC709). BTW, Calman's Absolute Luminance chart (for color) is great for this.
