Ive had the NX720 for about 3 days now. It replaced a new PN64D7000 Samsung Plasma. I can't see a difference with the NX720 as compared to the 810, which a local dealer still had as a floor model. I think the picture is excellent, even compared to the Plasma, so i'm not sure if 240 hz really ads anything. I think the motion resolution is pretty darn good, very close to the Plasma, so I don't know what the review at Television Info was seeing that I'm not.
The only issues I can see with the set are that some vertical banding is visible occasionally with panning shots on a light background, which I assume is a result of the edge lighting. Not sure if this is any better on other models or on full array sets like the HX929, as this is my first LCD. Can anyone with experience with other sets weigh in on this?
The other issue is crosstalk on aggressive 3-d movies like the Deep Ocean Imax Blu-rays. On studio movies, like Tron 3-d, it is virtually nonexistent.
