Can anybody tell me if a plasma screen with more pixels on it will give a better picture than a screen with less pixels but with a higher contrast ratio? (both screens are the same size). The reason I ask is I am on the verge of buying an Hitachi pd5300 but many people on this forum rave about the Panasonic pw7. Looking at the specs of them both the Hitachi has a lot more pixels but the panasonic has a lot higher contrast ratio, what is best? Help! Sorry if this is a daft question but I am really getting bogged down with screen choice and I really dont want to buy the wrong set up. Are both these screens High definition compatable?
