I see on my Panny U77 settings it has a specific "Brightness" level I can reduce, but what labeled level would I change to lower the Contrast? (Picture, Color, Tint, Sharpness, etc.)
I don't know the Panny U77 .
On most TVs/Plasmas there are two settings:
- Brightness - this controls where the black vs blacker-than-black setting is. In otherwords the setting of the dimmest part of the image. When your DVD sends "show this pixel as black", this determines how bright that will be. On a scale of 0-255, you should just be able to see 16, anything from 0-15 should be 'blacker-thank-black' and invisible.
- Contrast - this controls the brightest part of the image your tv/plasma will display. When your DVD sends "show this pixel as white", this determines how bright that will be. On a scale of 0-255, 235 should be as bright as you can get, anything from 236-255 should be 'whiter-than-white' and indecernable from white.
Don't worry about the 0-255 settings. You don't really need to know those.
Just remember 'brightness' is dark, and 'contrast' is white.
The problem with 100hour burn in, is that pixels age/decay more in their first 100 hours. So the trick is to get them to decay evenly. Lowering contrast, combined with filing the screen with random (Discovery HD) or predictably even (Evangelo2's dvd) makes that more likely.
In the longer term, your plasma in a year will be less bright than it is the day you get it. Because the pixels continue to decay over time. The rate of decay is inverse exponential, meaning it decays a lot the first 100 hours, and very little on day 365.
