I've been trying to properly calibrate my TV (Panasonic TX-P50UT50E) with my new bought Colormunki Display for some time now (few days), but it starts to get really frustrating.
First off, here's what I have accomplished so far:
I used the AVS HD 709 HDMV disc, with APL Large for the gray scale and APL small for the colors.
Now here is the greyscale with windows (and 20pt) instead of APL:
I really don't get what's going on here. How can there be such a huge difference between ~15% windows and 8% APL? Which one should I trust? I've heard that the ABL of the TV kicks in pretty early, but I don't really know how to use that information. Does that speak for the APL or the windows?
What's more is that, as you can see on both greyscales, blue behaves radically different at 5/10% than at (20)/30%. That's the reason I am having too much blue at 30%, if I alter the cutoff setting for blue only slightly, the 10% gray goes down almost 10%.
I have tried adjusting red and green instead of blue in the hopes, that I'll get better results, but that didn't work out.
Something similarly is going on with red, but the other way around. 5% grey, looks ridiculous, it's almost just a dark red.
I've been playing around a little and don't have all the graphs saved, but red and blue both look like a sin/-sin curve, where 0 is at about 25%, if that makes any sense.
If anyone has suggestions as to what to try next, i'd would be very grateful.
