Overscan is extra image area around the four edges of a video image that is not normally seen by the viewer. It exists because TV sets in the 1930's through 1970s were highly variable in how the video image was framed within the CRT. Overscan: The full image area to the electronic edge of the signal. There is no hard technical spec for overscan amounts. Some say 5%, some say 10%...
Someone better versed in electronics can explain it better than I, but my understanding is that 100% is everything that was recorded on film. The amount of information shown and not shown on my set between the two overscan settings is minimal. (I guess 97% to 100% is not that great?) If I switch to 100% on some of the material I've looked at I'll get video "garbage" along the bottom of my screen. (For example, I get a green line across the bottom edge.) If I switch back to 97% I get no green line and I lose very little picture information.
The settings I've been watching a few movies with are: Standard mode, Normal temp, Picture around +11, Brightnes around +9, Color at -4, Tint at -2, Sharpness around +15. All other video settings OFF except 3:2 pull down.
I've watched some stuff with these settings, but the blacks and contrast are not where I want them, so all these settings will be changing as the set breaks in. (And I actually sit down and read the owner's manual.)
