I've read somewhere that its best to keep it in cinema mode for the first two hundred hrs and then change things around. But never to put it in dynamic mode - in which case, whats the point of having dynamic mode in the first place?
Dynamic mode is the factory pre-set.Sony, Panasonic etc all set their TVs to Dynamic so that they look nice and bright in the show rooms.
If a Panasonic was set up correctly (cinema mode is close enough) next to a Sony in Dynamic mode in a shop the Panasonic would look dull in comparison and people would buy the Sony.
Dynamic is MILES away from a good picture.Contrast, brightness and colour are all ramped up to rediculous levels giving a totally unrealistic picture.
I have not got a clue why some people prefer Dynamic mode but a couple of days of Cinema should be enough to convince people the error of their ways as they return to Dynamic mode and need a pair of sun glasses to watch the screen.
