RE: Plasma Colour Banding

["Timothy Morris" <timothy.morris@xxxxxxx>]

What source? And what input? If on DVD set and it is adjustable on your
player set the black level to 0IRE, and try the settings I posted
earlier.

Each pixel can display 1024 shades of grey (more than all the other
manufacturers last time I checked) so you should be getting well over a
million colours.
