Just purchased a 55 inch 6 series Samsung LCD for my basement (kid's lair). There is a new menu option that I am unfamilar with. In addition to white balance where there is RBG gain and offset, there is also a 10 point white balance menu option which has RGB for each point. I suspect that this should allow me to dial in the white balance even further. So I have a couple of questions with regard to this. Does each of the 10 points correspond to a decile in IRE? Should I adjust the usual white balance first and then the 10 point? Any other thoughts or pointers with regard to this? Thanks

Yes the 10 point should correspond to 10->100.

Doing a 10 point as opposed to a 2 point, not only allows for a more even grayscale, but also correcting gamma (adjusting all 3 values up or down).

Thanks for the response. For an early on home enthusiast this will be quite enjoyable to play around with. I just ordered a ColorMunki today. This along with the Eye-One Display LT should work fairly well for the level that I am currently at.

The color munki is a great value, you should have alot of luck with that combination.

I would first set white balance using the Bias/Gain controls, then fine tune it with the 10 point. I say this because I tried using only the 10 point, but I reached a limit on the slider where I could not increase the blue high enough. This was on the 58C7000 plasma though.

Use a relatively high contrast setting, lowering backlight if needed to avoid problems with the 10pt white balance/gamma adjustment. At least for the Samsung Plasmas, the 10pt only works well with a high contrast setting.

Make sure you start at 100% and work your way down.

The Samsung LED backlit LCDs also works well with a higher contrast setting (94 or so).
When doing the 10 point grayscale / gamma adjust I start at the bottom and work my way up.

How do you do this when you need to ensure your reference white doesn't change?

If you set your 100% Yxy and make no changes to it, then you will be able to adjust gamma as you work your way down. Starting from the bottom and moving up won't work. If you do all the work from 10-90 and then change your Y at 100% you can kiss all of your work goodbye because 10-90 is no longer in reference to the original reference white, it will now be referenced to your new white point. Be prepared to see your gamma values be thrown out of whack.

Do 2-point first. Ensure you are happy with your reference white (eg. .313, .329 @ 40fL), then do steps 9-1. Depending on the Samsung, adjusting 9 will have a little effect on your reference white, so go back and forth until you are satisfied with both before you proceed to 8!

I don't mess with my Y at 100. I adjust 1 thru 9. And since i've found the adjustments on this unit to be independent and do not interfere with the others i'm fine (Tuning 9 doesn't affect 10. Tuning 8 doesn't affect 9, etc...)

Bingo. I found this to be just as you stated. And, even though I was unaware of this workflow at the beginning (I am still quite new at this), I did come to realize that this was the correct way to proceed.

I've been looking what order to do this for quite some time.
