The only thing I can help you with is the black levels. Go to "Complete Program Menu" -> "Advanced Video Test Patterns" -> 1080p or 720p -> "Video Black with new PLUGE.
There will be, in this order from the side, a bar that is below black by 4%, a bar 4% above black and the last is a bar 2% above (same on opposite side of screen). You want use the brightness contorl so the 2% above bar is barely visible and the 4% below is invisible. The 4% above is there for reference.
I don't know how to calibrate any other aspects of the picture without a color meter. I'm sure you can improve your picture without one but color accuracy will still, most likely, be incorrect.
This dvd is kind of like a nail without a hammer. You get all of the patterns you will need to calibrate your set but no unbiased eye. Calibrating with the naked eye is very hard if not impossible.
In order to get your picture as close to color accurate as possible you need a color meter like an Eye One Display 2 or a spyder 2. They cost about $100. On the plus side off that cost is you can calibrate any display in your home with it.
You also need a computer to plug the meter into (already have one) and tv calibrating software like ColorHCFR (free!).
Finally you need a tutorial to explain the procedure. I found a great one here: http://www.curtpalme.com/forum/viewtopic.php?t=10457 . Most of the info I threw out I regurgitated from his comprehensive tutorial.
Anyway, I realize you really need to be geek out to do all of this stuff but it does work well.
Well said as an accessible and inviting explanation for the uninitiated.
That information, along with the disk and the Curt Palme information, and some patience, and one gets the hang of it in relatively short order. It only looks weird and complicated, from the outside, to the uninitiated.
The immediate value of Palme's information is that it surprises -- and disabuses -- the uninitiated as concerns the correct color of, as example, grass, the color of which is typically enhanced to match one's imagination of grass, rather than matching the actual reality. In other words, HDTVs are typically, and deliberately, malcalibrated by the manufacturers in order to increase number of units sold.
