LG C1 65" white line on bottom and left of screen, only on Star Wars stuff on Disney

[tilapiah6]

So I tried to put everything in the title for reference. Basically, I am having a very specific isolated issue with my LG C1. When playing Star Wars stuff on the Disney Plus app on the TV, there is a thin white line on the very bottom and left of the screen. I tried playing the exact same things on Disney Plus on the PS5 and on Blu-ray using the PS5 and this didn't happen. What could be causing such a strange isolated problem? I tried turning the TV off and back on to no avail. I'm very new to 4k and OLED technology so please forgive my ignorance.

I think the C1 needs more updates. Also, the apps via the TV could also need updating.

I had seen this issue today on my C1 when viewing Pure Black on YouTube via Apple TV4K except the only difference was the white line was only visible on the horizontal bottom.

I haven’t run into any films yet on apps such as Netflix, Prime, Disney through Apple TV4K with this issue.

So it must be a random issue with updates needed then. My friend has a CX and he has a line on the bottom sometimes when he uses his Xbox Series X. He said disconnecting and reconnecting the HDMI cord from the TV usually fixes it. Obviously I can't try that method with an app on the TV.

I've had my C1 for less than 2 weeks but I'm finding an anomaly on 4k discs with HR10--- tiny white dots flickering all over the screen on dark scenes. Scenes with light are clear as day...

Nothing on regular blu rays or 4k discs with Dolby Vision...

anyone have any ideas??

HDMI (cable)?

• long shot - (in the dark)
• try? (swaping in another HDMI cable)?
• 'only thing that makes sense'
• HDMI (cable) - is it 'aa quality cable'?
• HDMI (cable) - is it 'High Speed'?

looks like it's the HDMI input on my Yamaha receiver--- I had to go from HDMI 1 to 2 to 3 and then all of a sudden all the white dots were gone!

I had heard that this receiver had issues with HDMI high speed but on my older TV it wasn't a problem---

Which film or show?

You can change aspect ratio in picture settings.
Default is “Original”
If it’s a widescreen SW film, you can try changing it to 16:9 to see if that helps.

I just checked out SW EPIII in Default “Original” aspect ratio. No issue.

If you can answer my first question, I can probably check it out later today.
