Partial black line on LG ltrafine 5k

[chacrat]

Hi,
I have bought a second hand ultra fine 5k on eBay.
I received it a few days ago and, today, I noticed a black line on the login screen.
This line disappears when I log in and it does not come back.
I rebooted and it happened once more (albeit not every time).
Do U guys ever experience this ?
Or is it safer to send it back ?
Best

I never saw that on mine and it’s definitely not something normal, I would send it back if it’s possible

Doesn't look like a panel problem since it doesn't extend to the edges of the display. I would keep it. If you got another 5K, it would probably show the same thing.
What computer/GPU are you connecting it to?

I am using a Mac mini m1.
Thanks

I've never seen that line on mine.

What's the arrow at the right of the line?
