Question

What does Shades of Gradation mean for a plasma tv?

Answer 1

It means how well the TV can display subtle variations of a color.

For instance, how many distinct shades of gray can it display between pure black and pure white.

Answer 2

lasma displays can suffer from an artifact called false contouring, where transitions between different shades of the same color are too sharp. These transitions can appear as distinct lines between the different shades of color. Having more shades of gradation helps minimize the false contouring artifact so color transitions take on a smooth, natural appearance.
