A couple of notes about calibration, color settings, etc.
We may all have LNXXD630s, but each set is going to show colors a little differently. First, these sets are assembled from bins of parts, which may each be just a little different than another. Second, the factory doesn't calibrate these TVs at the factory other than to preset certain settings to give an unrealistically bright and blue tinted picture.
With that in mind, any "calibration settings" you might find may or may not work for your particular TV. Chances are slim to none that the settings you find will be the exact settings that calibrate your TV to industry standards. They are simply the settings that happened to be be correct when CNET or someone else professionally calibrated THEIR particular TV.
The free AVS 709 disc is as good a free disc as you'll find, and there are some other ones available for some $$$ that are good as well. They will guide you through some of the very basic settings (brightness, color, tint, sharpness, etc), and will help you understand that sharpness should actually be near 0 instead of 100, and that "brightness" actually sets your black levels, while contrast sets your "white/bright" levels, etc.
With the sheer number of settings on our TVs, you'll drive yourself crazy trying to adjust by eye. Then, once you change a channel, you'll find that those settings might not actually be very good after all. Take some time to learn about calibrating TVs, what the different controls actually do, and then use a disc to try it yourself. If you revisit calibrating several times, and your picture still isn't where you want it, your set might require a professional calibrator to access the service menu and perform a 3-4 hour professional calibration.
If you guys visit the "calibration" subforum here on AVS, you'll find that no one shares "calibration settings" because that is sort of like sharing the forecast in Maine with someone in Florida and expecting them to take anything other than "Ok, now I know the weather in Maine."
