I am close to purchasing a new plasma. Either pioneer 436xde or panasonic phd8. How obvious is colour banding on panasonic screens, in dark to light transitions and dark scenes. I have briefly seen 436 pio and did not notice any banding or green dottiness in dark areas but noticed it on the panasonic displays. I find this a bit strange as panasonic has greater level of gradations of grey compared to the pioneer. please give me some advice and let me know your experiences.
