I think I notice more resolution when lowering my contrast level from 35 to 30. But since there is no definitive way of setting contrast, how do you know if it is too low? All the setup discs walk you through how to tell if it is too high(blooming, line bending), but not how to tell if it is too low. DOES lowering contrast level in fact increase resolution? And is there a definitive way to set it? I have a room with well controlled light, so I don't need levels that high... TV is Toshiba 57HX81, DVD is Toshiba SD5700. I already like the picture a whole lot, but looking for every little bit I can squeeze out of the set. Thanks for any advice.
