I'm really sensitive to this, It won't go away.
I had several plasmas, phosphor lag exhibits differently on every set.
trails can be reduced by overdrive like samsung does[if it is the right term, i;m not sure], but moving objects have little noise
all pannys have more or less green trails
but all plasmas I saw have rainbow effect when moving eyes from one side of the screen to another.. higher contrast/luminiscence make it more visible..
I see it clearly but it doesn't distract me
