Mine are in post 38 (on this page) although I have not finished messing around, in fact, those were just some quick ones that looked good to me. I will be playing around with it more over the weekend.

I'm puzzled that some are trying to adjust these 2 settings by eye. I prefer a TV that looks correct.

Well, I don't have my calibration disk yet, and when AVIA finally comes out with it, I will adjust accordingly. One thing I did notice about this tv is that the settings do not make nearly as big a change as they do on the 71 I had. For example, I went from my current color setting of 45 to your color setting of 52 and there was not a huge difference. Had i done that on the 71 you would have really noticed it.

That should have a lot to do with the fact that you have dynamic contrast on. When I was doing the calibrations with it on, the color control did absolutely nothing. But when you turn dynamic contrast off, then the color control does make a much bigger difference when changed. Try it out and see if it acts the same way on your tv

Same here. I used the Blue Mode and the THX Optimizer on the Incredibles DVD to set the color at 53, Tint at 50/50. I tried zerog6's settings for both Standard and Movie, but ended up preferring only his Backlight, Contrast and Gamma settings. I had the same yellowing experience as studdad with zerog6's White Balance settings, so I set them back to default. I will note that the THX Optimizer is only marginally reliable, as the same movies when "THX" calibrated don't look half as good as when using the settings from this thread!!!

Oh, I have an LN52A750 running the 1007 firmware with all "enhancements" turned off (black adjust, , dynamic contrast, energy savings, etc...).

All said and done, this set still looks FANTASTIC! I can't believe how smooth the colors are on the Pixar DVDs! I can't wait 'till Blu-ray 2.0 players appear so I can take that leap!

You know I noticed Dynamic with DNIe set to off has a better overall picture/better details than Movie or Standard no matter what settings I used with them. I wonder if there are something extra when Dynamic is turned on.

Yeah, I wish we could find out the secret. Whatever it is, it sure would be nice if you could use the detailed settings with it, at least the white balance.

Since you have so many instruments to do the tests, what did Dynamic Contrast option mess up the most?
Like did it completely mess up the gamma or make the blue too prominent etc...

I'm willing to buy the Blu-ray AV disc to calibrate myself, but only if there is some chance to get it somewhat close to 6500k & a 2.2. gamma curve with dynamic contrast setting on.

The 6500 you can get, that's not the problem. You can adjust the white balance to 6500 no matter what enhancements you have turned on.

But, It's impossible to get a correct gamma curve with dynamic contrast turned on. What dynamic contrast does, is increase the brightness or luminance of all colors, and decrease the luminance of blacks. So, when it's turned on, it basically makes anything with color too bright, and anything with less color too dark. And the higher the IRE value you go, it gets progressively worse.

ok I tried most of the settings & took some pictures, what does everyone think looks best?

Took 3 pictures of the same scene of the Blu-ray Silent Hill movie at 1080p via HDMI.
-Top pics using EVil4Blue HDMI settings that he came up with using the Blu-ray DVE disc for the A650 LCD.
-Middle pics using zerog6 HDMI settings that he came up with using Spyder2 colorimeter, ColorHCFR software, DVE-BD & AVS-BD, & Grayscale Calibration for Dummies Guide for the A750 LCD.
-Bottom pics are from cNet HDMI A650 LCD settings.

All three settings are way different from each one & all used calibration discs

I've just made some updates to my calibrations. I've learned how to adjust the color space so I've done so.

This is the new custom color space:
Color Red
Red: 56
Green: 0
Blue: 3
Color Green
Red: 38
Green: 60
Blue: 0
Color Blue
Red: 0
Green: 8
Blue: 76
Color Yellow
Red: 50
Green: 53
Blue: 0
Color Cyan
Red: 38
Green: 60
Blue: 60
Color Magenta
Red: 50
Green: 10
Blue: 72

Every other setting is the exact same as from my previous calibrations.
Except for Gamma
After calibrating the color space, I had to raise my gamma from -3 to -2 to bring the gamme curve back down to 2.2 because it went up to just under 2.3 now. Everything else is the same.

A couple of people mentioned that on their sets they're getting very yellowish colors when they tried my settings. So that's the first thing I tried to recalibrate to make sure it was right. And as a matter of fact, yellow was the most accurate color of them all that I have, lol. So if you guys are getting a yellowish picture then it's just that you need a different setup on your specific tv.

Oh BTW: I have FW 1007

So if anyone tries it out let me know how it looks on your sets

How did you learn to adjust the custom color space settings? I was going to go in there and play around a little bit, but I know if you don't have the proper equipment it would probably be tough to do right.

I thought I'd share my EQ settings. Anyone who tries them let me know what you think.

Mode= Custom
Auto volume= On
SRS Trusurrond= On


100Hz: 8 right
300Hz: 8 right
1Khz: 4 right
3Khz: 3 right

so i tested out your warm setting and the new custom color space... i noticed it really minimized my clouding with the backlight set @ 3 end energy saver set to low... i watched the good sheperd on hd-dvd and it has some pretty dark scenes the blacks and the color were solid.

i so far have liked ur settings the best. good job man.

btw, i noticed if i used dynamic contrast with no energy saver i get more pop to my picture and it totally gets rid of my clouding... i just get torn if i want more pop or accurate PQ.

You know I read somewhere that the correct gamma curve is supposed to be 2.5.
How would you think that would look on the TV.

Correct gamma is something that has been argued for quite some time, but the general consensus is that 2.2 should be your goal.

Yeah you can't do anything to the color space unless you have a colorimeter to take measurements. You need to measure luminance, and the x/y for each every single color and adjust them accordingly.

If you don't have anything to measure it now, I would suggest just leaving it on Auto. On Auto, it was already a decently accurate color space.

Also, sometimes they do recommend a higher gamma all the way up to 2.5, but that's a rare case, and reserved only for projection displays

zerog6, I tried your custom color settings and they seem good but when I compare to the native color setting(I believe, it may have been Auto) it looks almost identical. It doesn't appear as much really changed. Do you notice a huge difference?

It could be, remember that those custom color space settings are specifically for my tv, so chances are they won't work as well on any other set.

It's not supposed to be a huge difference, the Auto color space is already pretty good, usually all less then 10 points away from the reference. I wanted to get mine even better, so those custom settings bring my color space down to less than 3 points from the reference for all colors. But again, that's just specifically for my tv.

NOTE: I just updated the color space, I edited the original post, so check that again.

does anyone mind posting pics of their calibrated sets in a dark setting (with a black screen) at different angles? I'm just trying to see what mine is supposed to look like in case i need to return it.

Are your color space settings to adjust your xy on your primary and secondaries, or a % of your brightness?
