Color and all is nice on the TV but I just can't seem to get it to capture motion properly (not even talking about sports or fast motion just regular programming).
I already have it mounted and don't want to return as I think there are settings that can help. Anyone be my savior here?
EDIT - My wife uses this TV more and says it looks like a soap opera (she is not familiar with the "soap opera effect" terminology so interesting she described it that way).
However, what really bother me is the juddering, where it does not refresh right and skips ahead. I think soap opera effect and judder are opposite extremes? If you correct for one, you have to deal with the other??? Am I understanding this correctly? If so, it feels like I am doomed with this TV.
Fortunately, my main viewing is on a 60" Plasma which I have no issue with soap opera effect or juddering but I really want to get this other TV working right. It is very distracting.
I just bought a UN65KU650DF (Sam's). I use it primarily for OTA reception through a TiVo Bolt (4K upscaling). I am not real experienced with the new 4K TVs, but I instantly recognized these complaints, so I thought I would share.
I watch a mix of stuff from the Bolt, including plenty of old 4:3 TV shows. The first couple of days I had this TV, I was regularly bothered by motion "issues". Although I wasn't really keeping track of individual programs or scenes that had the problems, there was seemingly some judder or stutter or something on just about any program type. I have no clue what specific symptoms are for the terms "judder", "stutter" or "Motion Blur, but I was seeing plenty of things that just were not SMOOTH motion for brief scenes, and I did NOT like it. Unfortunately, I could not be sure if this was a TV issue, or a problem embedded in the recorded programs. I finally isolated a specific scene from an old TV show where the guy was turning in a doorway and his body seemed to jerk somewhat during the turn. This allowed me to compare the same scene on this new TV and my other HDTVs, and confirmed that it was specific to the new Samsung only.
I played with many of the internal settings, including custom motion settings (factory default motion setting was "Auto"), with no help at all. The key for me was when I finally just turned the motion settings OFF. Total solution so far!
Absolutely no more judder, stutter or jerk in any program source we have watched for several days. I am sure I have so much more to learn about this new technology, but thank gawd I found out how to turn this terrible feature OFF!
Now, one more comment specific to the curved screen of my TV (not motion related):
I wish we had bought a flat screen and NOT the curved one! I have not seen this discussed yet in my limited research, but in certain specific viewing settings, the curved screen works just like a dentist's light to focus reflected room light directly back into your eyes!! What we have found is that the curved screen is BAD when there are any lights on directly above or behind the viewer in a straight line to the center of the screen.
We have theater seating directly in front of this TV and about 15' back. We also have a sofa light directly behind these seats with the light heads hoovering several feet above these seats, and then our kitchen further straight back has lights on the ceiling about 15' high. When the sofa light is on, there is a bright line of light directly through the entire center of the screen from left to right. When the high kitchen lights are on, this reflected line of light is up near the top of the screen, which is not near as irritating, but still not good. Flat screen TVs in the same location have never had any reflection problems at all - just this new curved one. The problem goes away when moving the viewing angle any amount at all from dead center, but with a curved screen dead center IS THE PREFERRED LOCATION! So beware - avoid the curved screen if you will be sitting directly centered on the screen and have any lights in the room above or behind you in the same line of sight.
