I've found the expert settings let you set it at low, medium, or high for the calibration setting, but didn't find how to alter the numeric setting for those levels. I'm hating the ramped up settings on the new firmware (1007), and would love to have a lower setting than the new "low" for DirecTV shows and movies.

Also, those screenshots look like they're from the new Fantastic Four movie, which I just watched last night. Maybe it was the martini I had, but the AMP on low still bugged the hell out of me in that movie, were you as disturbed as I was?

On my set, your settings were a bit too warm. I changed the Warm setting to Normal and it looked good. I got a lot of yellow with your settings. Just a difference in tv's. I did a quick adjustment on my tv last night, and what I liked best was the following (just a quick adjust, so more to follow later):

Mode: Standard
Backlight: 5
Contrast: 87
Brightness: 42
Sharpness: 15
Color: 45
Tint: G49/R51

Black adjust: Low (tried Med, and liked it too)
Dynamic Contrast: Low
Gamma: 0
Color Space: Auto
Flesh Tone: 0
Edge Enhancement: Off
xvYCC: Off

White Balance:
Offset
R: 27
G: 25
B: 24
Gain
R: 25
G: 25
B: 25

Color Tone: Normal

Edit: oh, and film mode off. One thing I do wish they would allow is DNIe in standard mode. It gives a little extra pop in Dynamic Mode. I adjusted Dynamic Mode and got it close to my Standard Mode, except it was a little cooler, and without the ability to change the white balance, I couldn't warm it up a bit. I liked the extra punch that DNIe gave it when turned on, but just too cool for my taste.

On all 3 sets, all blue blocks matched the blue background with Color at 52 and Tint at 50/50. I'm not sure why anyone would play with the Tint setting on these sets.

I did get better contrast with a bit deeper blacks, but with it on, it was impossible to get the colors very accurate. So just so you can know what the compromise is. I eventually have it turned off now

About Dynamic mode, in case you didn't know, the only difference in settings between dynamic and standard, is that dynamic has both black adjust and dynamic contrast set to "high". Everything else is pretty much the same.

I'm gonna try and do a calibration in standard mode with a normal color temperature, and maybe try dynamic contrast on low again to see is there's a way to make it work.

Isn't it funny even though it's the same tv for the settings to be so different

Tools: Spyder2 colorimeter, ColorHCFR software, DVE-BD & AVS-BD, Grayscale Calibration for Dummies Guide: http://www.curtpalme.com/forum/viewtopic.php?t=10457

Final Settings (for now, lol):

Mode: Movie
Backlight: 3/dark 4-5/lighted
Contrast: 92
Brightness: 43
Sharpness: 10 for BD / 20 for DTV
Color: 42
Tint: G50/R50

Black adjust: Off
Dynamic Contrast: Off
Gamma: -3
Color Space: Auto
Flesh Tone: 0
Edge Enhancement: On
xvYCC: Off

White Balance:
Offset
R: 28
G: 25
B: 21
Gain
R: 26
G: 25
B: 29

Color Tone: Warm1

Now here are my notes:

Contrast: 92 / Backlight 3-4
According to the guide, the contrast levels should be between 50-60 FTL. With the default, I got measurements upwards of 70. After taking several readings, the best backlight is between 2-5 depending on your lighting, optimum would be 3-4 and the contrast at 92. This setting gave me just decimals over 59 FTL with the backlight at 4 and just over 50 at 2. You can go to 5, but that's if you're room is extremely lit up. And I prefer to keep it at 3 instead of down to 2 in the dark just to get a bit more pop.

The luminance curve was pretty spot on

Brightness: 43 / Gamma: -3
This was set according to the contrast measurements. I still want to work on this a bit more. The entire combination between contrast, brightness, gamma and backlight can be confusing. But i'm getting the hang of it now. Gamma at -3 was the only way I was able to get the great black depth and shadow detail while maintaining the contrast.

The gamma curve was right at 2.2 between 30-80 IRE. Below 30 IRE the gamma curve went down to 2.1, while above 80 IRE the curve went up to 2.3, so I'm pretty happy with that as well.

Color: 42 / Tint: 50/50
I used the Red & Cyan test pattern from the AVS-BD. According to the measurements this is pretty precise.

Greyscale:
The greyscale readings were incredible, according to the guide, lol. The only thing was that I could not get a proper reading at 0-10 IRE because of the colorimeter so I don't have values for those. But check this, between 30-80 IRE, "all" of my deltaE measurements came in under 1. Yes, all less than 1. The only deltaE values I got above 1, were at the 20, 90, & 100 IRE, and they were not far behind. at 90 & 100 IRE I got a deltaE of less than 3 for both. And the reading that was furthest off, was at 20 IRE, which had a deltaE of 5, which isn't even considered being off, lol.

Seems like some models have different values even between the same size & firmware.

In terms of greyscale, I got the set pretty much just as accurate to D65 as I had on Warm1. There was more fluctuation in the measurements, and they weren't as accurate across the IRE range, but all the numbers were still under a deltaE of 10, and most under a deltaE of 5. So in general, it was not quite as accurate as Warm1, but I doubt you can visually tell the difference.

Here are the white balance settings I got:
Offset:
R-26
G-25
B-19
Gain:
R-32
G-25
B-23

Now, Dynamic Contrast, and Black Adjust. In terms of color and luminance accuracy, this throws everything wayy off. Either of the 2 makes the gamma and luminance graphs go literally off the charts. So there's no way that you can get an accurate picture using those enhancements.

Color & Gamma controls are literally useless when dynamic contrast is on, which leads to some of the inaccuracy.

HOWEVER, to my eyes, Dynamic Contrast still looks really nice. So even though it does that, I still consider using it depending on what I'm watching.

All of the rest of the settings are the same except Gamma's at 0 for these settings

However, from what I have heard, you can't play videos wirelessly using this item. But, you can do all the rest (weather, infolink, pictures, music) Can anyone comment on this? Anyone have one?

For reference as to where I found this offer: (see top of page)
