There are a lot of things to take into consideration. The room you are in, how big a screen, they type of screen, and there might be slight differences in each unit.
But , this is a great thread, because we can get ball park settings.
I've mentioned it before, in our regular PA70G thread, do the "picture wizard II' setup stuff, then place a hdtv next to 70G and watch the same recorded tv/movie at exact same time, and adjust settings on PJ until it's as good as the hdtv. I did that, and it looked amazing. If you don't have that reference hdtv screen, hard to tell how it's suppose to look, and the camera work in the movie might not look good, so having both set side by side, you can see , "oh, the hdtv picture on that scene looks like crap, so of course it will look like crap on the PJ".
Also, maybe people can post 3D settings that make the 70G POP.
