I have seen quite a few demos of the Toshiba 42" and Pioneer 37/42" Plasmas and am generally very impressed. However, in all cases, I have seen an effect which I can't really describe. Bascially, when you get an area with gradual shading, there is an irregular shaped patch within this area, which kind of shimmers/flickers and just looks strange.. I have seen it most on backgrounds, when there are large areas of soft shades. For example, a blue Sky in one video had a large area which had the shimmering effect I am trying to describe. I know that Plasmas suffer from 'solorization', but is this what I am seeing. Does anyone know what I am talking about??
