Here's my grayscale readings. All of excellent except the first one and it's not bad by any means, just not as good as the others. Average gamma is at 2.28 and contrast at 3,244:1, which is the highest I was able to record.

The color space is pretty good, but I wish I could get the blue and red primary colors exactly where they're supposed to be, but simply can't. I've tried everything and spent many hours trying to get those correct, but I just can't figure it out. In fact, the only way I was able to get red even close was by using the color and tint settings to set red. Otherwise, red was way off and inside the triangle. It looks like I simply need to rotate the triangle slightly using green as the anchor, but I can't figure it out. If any of you experienced calibrators know how to do that, please let me know!

Overall, I'm very happy with it. The things that are slightly off are probably not noticeable by eye, so I'm not worried about it. I'm sort of a perfectionist, so it bothers me that I can't get the color space exactly right, but...

I'll post my new settings later.

Loads of thanks to turboman, prsut, jestered, and the rest of you for your help and knowledge sharing so far. It has really been immense.

One quick note, the forked version of HCFR has recently been updated with better colormunki support. If you choose "image generator" instead of "dvd" as your generator then HCFR can blast out its own color patterns, which greatly speeds up reading levels vs having to do it manually. I'd estimate it saves around 5 minutes for each full reading of grayscale and color. If you do use this updated version and the built in image generator (you really should, it saves loads of time), make sure to edit the generator settings to change the window size to 30% or so of screen so that way you get window patterns instead of field patterns. I've linked the latest version in the post in my sig.

The biggest difference now is that I am only using minimal 10pt adjustments at levels 8,9,10 instead of the mess I had earlier. I also took on the advice of others and after calibrating my colors I read some posts talking about calibrating colors at 75% saturation/75% luminance. I went ahead and calibrated for those levels after calibrating my 100%/100% color levels, and then checked back on the 100% results to make sure things werent too far off.

It is funny, I had the worst time trying to get my gamma and grayscale levels set correctly, but color calibration was nearly spot on the first go-round. I estimate it took me 3-4days to get the grayscale right and maybe 2hrs for the colors, quite the opposite experience of Jestered. I wasn't able to get quite the contrast levels that Jestered got, but I think thats mostly down to the colormunki being pretty inaccurate at very low light levels. My final calibration is for 48ftl at 100% brightness, which is a little too bright, but those levels got me the best overall results.

Click the link at the bottom of my sig if you are interested in seeing the full details on my calibration process and results, and the picture settings I have settled on.

Here is a summary of settings and results, but the link in my sig has some important notes/caveats for anyone looking to try these settings out (especially the note on gamma)
Here's my results file you can load into HCFR calibrated result.zip 2k .zip file

And the settings to get the above results: Settings (Click to show)
:edit: Having just watched a few movie scenes to confirm everything I think it is debatable whether the brightness setting could be a tiny bit higher. The final scene of dark knight rises where he is walking through the water in the cave just before the credits was losing some shadow detail that I could see if I turned the brightness up to 44. 45 started to raise the overall brightness of "black" and didnt really add much additional detail in the dark areas. Of course, this is all with my face 6" from the screen examining tiny color highlights on water splashing off rocks so who knows if it makes a difference from couch length. I'm certainly not going to rerun all the tests and recreate all of those charts for just this but I thought I would throw it out there for anyone trying my settings and maybe wanting a tiny bit more brightness/detail in the darkest areas. I wouldnt go above 45 bright with these settings though.

I can see why people want a new thread in order to focus on best settings. I had this middle of night brainwave that we could create a master document in a table (doc file) and enter the settings in a standardized format. So I spent the better part of this afternoon resetting my 65 and copying out the settings for my model and panel in a table format (I use Open Office). I entered all the default settings for Standard, Movie and Natural in a 2-page table. This took awhile as my PC and TV are at opposite ends of the house. My thinking was that members could delete the default data and then enter their own settings for their model and panel and then we could keep adding to it and updating it, like Garnoch does with the Guide. That way we could have an ever growing document of settings for different panels and based on calibrations, personal preferences, good luck, etc. It would be a standardized work in progress.

The problem, probably anticipated by many of you, is where to store this document so we can all access it and add to it. It'd be great if a file can be attached somewhere to this thread. Or perhaps someone has a website and they could store it and give us all acess to it. There are online services like this and I used one last year at work but can't remember what it was (it's been awhile). Anyways, I did my anal part and created a default master document of settings for the UNxxES8000. Now we need a storage and access solution.

Cheers,
Canadian

That looks very good. I am especially surprised about your very high contrast ratio. Really fantastic. You have mild clipping at 100% but dE is still acceptable. But I would be happy to have this contrast ratio despite the mild clipping. So it seems you are at the limit of the Movie mode.

About the dots in the triangle , I would not worry about that. More important is to have minimum dE errors. I did not see any graph with your color dE errors. Can you add them please?
Since you have mild clipping at 100%, it would be preferable to do the color calibration at 75% luminance. Even better would be to do the calibration at 75%saturation/75%luminance. I saw now that Fork of HCFR has that capability:

I think it would be worth checking Fork of HCFR.

You have a mild slope in the gamma curve. Maybe due to the mild clipping. But I would not worry about that. That slope goes in the direction of a BT1886 calibration. For BT1886, see this thread, post 175. Fork of HCFR also has BT1886.
