there is a disc called video essentials, not cheap, but explains things. Does video and surround audio system set up too, has all the test patterns you would need.
I just bought the Panny 50U and am trying to calibrate the TV with the included Circuit City DVD. I am having trouble with calibrating the contrast and sharpness. #1, on the remote control menu, there is no contrast setting. There is brightness, color, tint and sharpness, but no contrast. I am assuming the the picture setting is the contrast, because the manual says the picture choice controls the "whiteness" of the TV. Also, the tests are difficult to understand and the host of the video doesn't explain things very well. Anyway, does anyone have any ideas on how to properly calibrate my plasma. I know that there are some calibration dvds out there to help. But, like the Circuit City dvd, I'm afraid that the explanation of the tests will be lacking. Thanks for any help.
