Because of all the rave reviews the Samsung seems to get and the fact that I keep getting told the black levels now beat plasma, I think I am going to buy one for my conservatory instead of a Panasonic PX70 plasma. However I notice the specs say that the 40" has a 15000:1 contrast ratio and the 37" has an 8000:1 contrast ratio. Now I am a firm beleiver that contrast ratio means absolutely nothing, I would much rather they put the light ouput when showing absolute black as this is what makes a picture have depth. So has the 40" got blacker blacks or is it a case of the whites can go brighter?? I really don't want to go any bigger than a 37" as it is just for the conservatory and I don't want a massive set dominating the room, but if the blacks are definitely deeper with the 40" I will have to reconsider. Hopefully someone has seen both??
