No smearing of colors or DFC. No DSE. Saw cricket and tennis on HD. I tested for DSE when the camera traces the cricket ball across the field or sky. I keep looking for it but nothing that makes me doubt Samsung's panel driving method. Yes, there is slight band that is momentarily felt when camera pans across a solid color like the transition from starry sky to tea garden in Life Of Pi. It's for a split second and you have to replay the scene multiple times to notice. I then read in other forums that this is the case with most owners. So nothing to worry and it is hardly there.
Are there specific test sequences you want me to try and report?
Am impressed by this 64" model and it is hard to please me when it comes to flat panels.
