When I convert this testpic.mpo (using USB) to 3D by pressing the 3D button on the TV remote, I can see only a little 3D effect on the Full HD and the 3D label by wearing the 3D glass. I am not sure that is normal, or I wonder my D6500 TV is not even converting 2D to 3D. Anyway if I play 3D movie from my samsung BD-D6500 3D player, it looks very sharp on 3D effect.
I don't think I am lucky to have the 1080P HD on 3D. I think all the model from D6420 and up are 1080PHD on 3D movies. I bought my TV in Futureshop (Canada). They have demo on the floor with UN-55D6420, UN-55D7000 and UN-55D8000 playing 3D movies all day long. Customers can wear the 3D glass and see the effect any time. When I went there and see the demo, there are no difference in picture quality (3D) among those 3 models. Maybe D7000 and D8000 is a little better because it is more expensive, but not huge difference. I bought the 55" at the beginning, then exchange for the 60". The first one I got was good too, just not big enough.
