Dont know if your TV has this, but try turning off the "Motion Plus" option. See if it helps.
I bought this TV(Samsung UN46B6000) just a couple of days back and connected it to a blue-ray player as soon as i got it and played a movie. And the movie just feel like a reality show where they show how the Movie is made rather than feeling like a movie.
I absolutely have no clue how is it possible, but my TV is playing movies like reality shows. And i have tried calling customer service and even they dont have an answer.
I played some movies which are action filled like District 9, Dark Knight, Terminator Salvation. All of them are blue-ray discs. The picture quality is great but they just dont feel like movies.
I have even tried playing movies by connecting my HDD, same result. If i play them in a different TV(My friends Sony LED) they are just like movies. Even in my laptop they feel like movies.
I would rather watch movies in my laptop than in my TV if it plays like this.
Is it a problem with Samsung Tv's? Or is just some settings i have to change? Help me out with this one.
