    LG OLED here as well - don't have the issue.

    @gio12 - are you using a universal remote setup? If so, you could mess with the timing/order of each component turning on and/or off. I use a Harmony for my setup (LG OLED/Denon AVR/C61K.

    I don't know the order and/or delays in my setup as I never had to look at it - never had the issue. If you think it would help, I can retrieve and post the info here if you would like.

    I agree - it sounds like a handshake issue to me.

    I am not using a universal remote.
    Both have new high quality HMDI cables and different brands.

    Have tried at least 8 different HDMI cables and same issue.

    Oh well at this point.

    think there's enough evidence around this is a timing issue. The TV does not respond fast enough to the C61K startup. That's why some TVs don'tshow the problem at all.

    It's probably not your cables - it's timing. Try doing what my setup does, but manually. Turn the C61K on, wait 10 seconds, then turn on the TV. If that doesn't work, do the opposite. If you have an AVR in the mix, try all the combinations waiting 10 seconds between each.

    If that doesn't work, it may be happening at shutdown. Do the same things while turning stuff off - waiting between each event.

    Also make sure nothing is on standby - TV, AVR or C61K (if that's even a thing for that) - when testing.

    You won't need 10 seconds on a permanent basis - do this only as a test to see if it resolves the issue.

    Here is the order for my DirecTV activity while using my Harmony Elite:

    Turns system on:

    LG OLED turns on
    LO OLED switches to HDMI2
    Denon AVR Turns On
    Denon AVR switches to CBL/Sat Input
    C61K Turns On
    Universal Light Controller Turns On

    Turns system off:

    LG off
    Denon off
    C61K off
    Light Controller off

    I do not use these things,
    but,
    usually you turn things off in the opposite sequence that you started it up.

    Light controller off
    C61k off
    Denon off
    TV off

    Have you tried this sequence ?

    Edit/ Add: If you turn the TV off first it can not longer tell the Denon or the C61k what it is capable of and possibly cause the C61k to change the setting for the resolution.

    turning off does not make any difference in turning on sequence

    I have not tried any other sequence. It's just **** luck the way I set it up - there was no thought about the order or delay at all. Because it works, I've never had to think about it, although I do know it can be important for some.

    I'm going to leave well enough alone - if it ain't broke...

    Common rule: turn on peripheral devices like TV/projector (HDMI sink device) first, then repeaters (AVR, switch, etc ), then HDMI signal originator (host or source) - STB, BR player, etc

    Not sure what you mean but I am saying that the new c61k and the c61k it replaced both stuttered while the c61 I swapped in and used for a year never stuttered. As soon as the c61k was re-installed the stuttering immediately returned. So to me this means that the problem is absolutely 100% a c61k problem.

    All channels in HD. it's doing it now for Sports Center on ESPN. Every broadcast channel. Like I mentioned, if I swap in the c61 the problem goes away. No problems with Netflix or Amazon or You Tube. It seems that we have eliminated every possible gremlin except the c61k itself. And yet I seem to be the only one having this issue. It is very perplexing for sure.

    Certainly sounds like you're right. Also sounds like the folks talking about proper sequencing are correct too. Might want to try Athlon's suggestions.
