Even with these settings, I cannot get the 'Ideal' white items to completely disappear. My backlight is set at 27 currently. The Contrast setting is obviously high, but it seems to be correct according to the calibration screens. I noticed that my BDP has a Black Level setting, which I set to 'Darker'.
Also, the calibration suggests that I set my Gamma to 'High' to get the 2.2 gamma bar to match the 'gray scale' background. This seems to counter what I have read which suggests you should leave the Gamma at the lowest setting.
Does this sound correct? Has anybody else used Disney WOW to calibrate their 47LD520?
To be honest, I really like the WOW BD for some of the test patterns (black pluge, advanced black level, integrated compound test chart), but there are other things I find it isn't the best at, e.g., setting contrast, sharpness.
Be careful with contrast settings since you're not only concerned with clipping, you have to be concerned with discoloration at high contrast levels as well as having it set too high and causing eye fatigue based on your viewing conditions.
The gamma response pattern may be a good, ROUGH guide to what your display is producing, but it's not useful for setting gamma accurately. I'm afraid you're in professional calibration territory to do that correctly.
Also, be careful about choosing the 'dark' setting for source components unless you know for sure that's what it should be set to. Many times it will crush blacks when set to 'dark' and you might be losing shadow detail.
All that said, when I'm doing a final check on things after I do a calibration, I rarely rely on just one test disc (like WOW) because there are things each of the other test discs (DVE, AVS-HD 709, Spears and Munsil) are better at. You have to cross-check to be sure.
By all means, have some fun with set up discs like WOW! They're a great way to learn about this stuff.
Of course, I'm biased, but if you just bought an entire new HT system, my recommendation is to find a professional calibrator to get all the components talking to each other the way they should and have your display give you the best picture it can possibly give you with your current equipment.
