@ makingmusic476 )

but 1080i CRT -> 1080p (high quality) LCD makes a tremendous difference for HD

What??? Are you implying you still watch in Vivid mode?
That's a big NO NO.
you should PM makingmusic476 for the calibrations(I think he'd be more than happy to help), he also has an xbr4, I can't help since I need to go to bed.
Trust me though, custom beats Vivid by a huge margin if done right.
You need to play with the picture settings for a set that expensive.
Good luck.

Thanks man for the help,,I ll pm him as soon as I find his ID here,casue I have no Idea how find a username on this website

Yeah, Vivid Mode is the eye scorching mode that they use to show off the displays in stores.  It's made to make the colors really pop (making them more impressive on the initial viewing), and to counteract the bright lighting in stores.  

As for calibrating your set, it really depends on personal taste, but I can give you mine, which will definitely be far better than Vivid Mode, and then you can adjust things yourself from there.  Hang on, and I'll go get my specs. 

thanks man for the help,,greatly appreciated,,,I sent you a PM about this ,now you can disregard it.

It's a brilliant TV ,,I love the matt glass panel instead of samsung's shiny panel.I got the samsung first and it was almost invisible in the mornings when the room was bright.So I switched to this Tv and I am lovin it.

Yeah, the clear panels generally give displays a slightly more 3D pop, but the glare makes it not worth it, imo.

Here are my settings:

(Note: If it's not mentioned in this list, then leave it as is)

Custom Mode

Click the Home button and go to Picture Settings

Backlight 4
Picture 76
Brightness 54
Color 52
Hue 0
Color Temperature Neutral

Click advanced settings
Click White Balance

R-Gain -2
G-Gain -3
B-Gain 0

R-Bias -2
G-Bias -1
B-Bias 0

Go back to Advanced Settings

Detail Enhancer Medium
Edge Enhancer Low

Now those last two and a few at the beginning I'm not sure if I adjusted at all, so I listed them just in case.

Also, you have to select which mode you want (vivid, theater, custom, etc.) on each input mode individually (Component 1, HDMI 1, HDMI 2, etc.).

And my settings are aimed at a more realistic, natural look, particular in human skintone. At first it may seem a bit dull, because you are used to Vivid Mode, but compare it to the world around you and it should be spot on. A good demo film for this would be Pirates of the Caribbean: Dead Man's Chest, as it does not use any strange post production color tinting, and it is one of the most detailed films yet released on Blu-Ray.

After a few days, go back to Vivid Mode, and your eyes will bleed, lol.

"1080i>1080p shouldn't be that much of a difference, far less than 480p>1080i, unless you had a superb upscaler. "

He had an CRT 1080i. HD CRTs simply suck (yes I know better colors yada yada), doesn't have anything to do with the resolution.

Good point about it being a CRT. I didn't notice that. ^^

Most of my friends have 1080i tvs and they all bitch saying that they wish they had waited for 1080p like mine. I think the difference is huge.
