Weird “banding” issue with my TV

[rexcrk]

I think “banding” is the word I want to use, I’m not entirely sure though lol.

It’s like a horizontal “block” that goes across my entire TV. It’s more or less noticeable depending on what I’m watching and what’s happening on screen. It definitely seems worse during dark scenes. And it’s also more noticeable during a camera-pan up / down.

Like right now I’m watching the first Captain America movie on 4K, and the opening scenes (when they’re digging in the ice, when Schmidt finds the Tesseract, etc.) and it was VERY noticeable, but during the outside scenes at the camp (when we first meet Peggy) the “banding” is barely noticeable. I’ve noticed this issue with other 4K discs too.

It also seems to be worse depending on what format I’m watching. Like, if I’m watching something like Curb Your Enthusiasm or The Simpsons on DVD, I can’t even tell if my TV has that “banding”. On some Blu-rays it’s very noticeable and on some it isn’t. Again, depending on if it’s a darker scene or not.

The weird thing is, if I stream, then those problematic scenes in Captain America that I mentioned, aren’t bad at all, in fact the problem is pretty much non-existent. And that’s streaming from both my 4K player and just on the TV’s app.

So it seems to be mainly disc-related, especially 4K discs. Could it be the result of HDR mode? But that wouldn’t explain why it happens with non-HDR Blu-ray Discs too. I don’t know if this is a common issue or not, but any help would be much appreciated.
