Moire Patterns and Dark Knight

[stahl7639]

Alright, this may be a “noob” question/complaint, but I cannot stop thinking about it. I recently purchased a new TV, a Samsung LN40A650, and I love it. Last night, I plopped The Dark Knight into the PS3 and started watching it. I was immediately disappointed when the opening IMAX scene began because all I could notice was the horrid moiré patterns on the buildings. I noticed these during some of the other IMAX scenes in the movie as well. Now, my question is what is causing these patterns on my TV? Could it be my HDMI cable, I have a Monster FlatScreen HDMI cable that I bought in 2007, so maybe it is not 1.3a? Could it be a setting is not turned on on my TV? Any information would be greatly appreciated?
