    Watching Thursday night football via Fox 4K channel yields constant video jitter. When I switch to the 4K signal directly via my TV (LG OLED), taking the DTV hardware out of the equation, no jitter. Seems like maybe DTV's compression is screwing up the video playback. Is this a widely known issue? It also occurs on channel 104 4K broadcasts. This isn't visible on non-4K channels.

    What "Fox 4K channel" are you viewing directly on the TV? Are you talking about the Fox Sports streaming app? If yes, you are comparing apples to oranges.

    Some have reported that to eliminate the jitter, you must tune to a channel on the C61K that is broadcasting in 720p (e.g. Fox), and than switch back to the 4K channel.

    The OP did not specify what SW level he has, so he may not have received the fix yet. Otherwise, perhaps you can suggest another reason why the OP has the issue?

    There is no way he hasn’t.

    He's also able to "switch to the 4K signal directly via my TV". Something is weird about his OP.

    Maybe he lives in California and hasn't had power for a month.

    I just got a new LG 43UM6950 and I'm noticing this too. I have it connected to a C61 client. Don't have a 54 so no 4K here.

    It's driving me CRAZY! Is it my TV, or something with the signal? I swapped out the client for another from a different room and saw the same thing.

    I did not try taking the TV upstairs to another location yet, which I thought maybe would rule out a bad coax connection? I will try a new HDMI cable first.

    Make sure the video output settings on your DVR (which one do you have?) match the settings your new TV can handle. If that's not it, then take a look at this:

    https://www.techwalla.com/articles/how-to-stop-jitter-on-a-lcd-tv

    And from Rtings.com about your TV:

    "The UM6900 can remove judder from most sources, as long as the Real Cinema setting is enabled. Unfortunately, it can't remove judder from 60p or 60i sources, like a cable box."

    He has an LG set. Similar model numbers can be confusing. Be nice if the makers of TV sets would do something about this. They appear to be using the same method truck makers use, for instance the Ford F-150 has similar specs to the Ram 1500 and I think GM uses a similar scheme. Yeah, 150 means a ton and an half but it can be confusing. Sony uses numbers similar to Samsung's model numbers too. You can buy a 900 Sony or a 9000 Sammy. Similar numbers. Gets confusing.

    I know you know all this, thought someone might be interested. I never noticed this until I began searching for 4K sets in 2015. I thought similar numbers meant similar specs as they do in trucks. I was wrong. I bought a Sony 850 (it was either a "C" or "D") and a Samsung 8500. Similar numbers. Still have the 8500, still haven't changed many settings. The Sony lasted about 3 days and was returned. Similar numbers, not similar specs.

    Yup - saw that - a non OLED LG. The quote I posted from Rtings is from their review of a very similar model to his.

    LG UM6900 Review (43UM6910, 49UM6900, 55UM6910, 60UM6900, 65UM6900, 70UM6970, 75UM6970)

    Huh. Same number different letters. I know any Samsung set beginning with "6" is gonna have judder issues that can be fixed. In the NU6900 review it says: but motion handling is only mediocre. In the review of the LG set it says this about motion: The UM6900 can remove judder from most sources, as long as the Real Cinema setting is enabled. Unfortunately, it can't remove judder from 60p or 60i sources, like a cable box. Kinda makes me think judder is something anyone having this set is gonna have to live with in some cases.

    I was quoting @mrknowitall526, not the Op.

    I have to play around with it some more. The TruMotion settings create the soap opera effect. There is a custom de-judder setting that maybe helps a bit.

    It only happens on certain channels, it seems, and at certain times.
