OK, so sorry to add confusion by posting numerous setting options- however, just dialed these in and the Cotton Bowl looks AWESOME. I turned the antiblur up to 10 and antijudder up to 8 (since it is football - otherwise I would not go above 2 on the antijudder).
Found these in a post on **************.com from davidjschenk. Apparently he has some calibration tools. Here is what he says:
"In order to flatten the gamma, I had to give up some accuracy in the grayscale, especially with that nasty, nasty blue dip at 20 IRE, but visually I really didn't see much trouble in the grayscale, and gamma is now at least reasonably well-ordered. Color accuracy under Auto is surprisingly good, especially with Gamma -1. The secondaries are just spot on and the primaries, while a bit off, are much closer than I expected.
This thing is PHENOMENAL. My minimum light level came in (get this) at 0.0000. That is not an error; that really is the result my C5 delivered. The backlight, of course, did not turn all the way off because I worked very, very hard to stop it from doing so (it wanted to--believe me), but I managed to get it so dark that the probe couldn't catch the emitted light. Hah! Peak light was around 38.5, which I know is a bit high for some folks, but really, it worked fine. And this way my gamma is at least fairly flat."
Contrast 86 (going higher turned my high-end grayscale VERY RED)
^^ these two were ridiculously accurate
Digital NR Off
AMP Antiblur 4 (but all the way up to 10 works fine with no discernible artifacts)
Local Dimming On
Color Space Auto (grrrr...)
Gamma -1 (This was hugely important for flattening the gamma and (sort of) controlling the blue hump.)
