There are a *lot* of settings for color space and gamma in the service menu. Without specific data on what each register represents, I've basically stuck to user menu settings for now. My current settings are in the post linked by my signature, though take note that my white balance settings are directly tied to my hue modification. Also note that my S3 TiVo input has the only useful set of settings for most people.
I should probably get at least a moderately-useful meter if I'm going to go further with tweaking things like grayscale. Right now I'm eyeballing it. The steaming rat method of calibration has served me well, but it's invariably true that when you get certain things (e.g. gamma curve) dialed in accurately, it will make other settings better, even if they're subjective.
Since I work with low-level graphics programming for a living, I'm actually really good at seeing color nuances, especially on a grayscale. Thus, I think my grayscale is pretty consistent from top to bottom, but that doesn't mean it's true 6500K and not tinted. It could be consistently tinted blue or orange, since all I'm doing is making it consistent.
I've been looking at the pre-calibration report strutter posted that was supposed to be using my settings, but I'm having a hard time believing my grayscale's temperature averages about 11000K and gets considerably higher at the low end. My grays are just not that blue, and my low end certainly doesn't seem to be that purple. I guess our sets could be really different, but I doubt it. I think maybe his calibrator reset the user settings before starting, because the factory default settings are *very* blue, just like the pre-calibration report indicates. So, I have no reliable data, except from my eyes, to tell me how accurate my methods have been.
Let me (us) know what you come up with in your own attempts. I'm sure many of us would be very interested.
