Purchased the Samsung 60" JS7000 4K and haven't taken it out of box yet due to second guessing myself. I paid $1,599, so I believe I got a good deal, but I'm wondering whether this TV is a good choice overall. We are not gamers. The TV is mostly used for sports and movies, so I'm worried about judder. Don't REALLY know what that means, but I see it's a big topic. I'm also worried by the fact that the motion is only 120, and not 240. Please help.
