Are these dead pixels?

[aleks0801]

I just bought a new Samsung mu7000 yesterday (so yes, I have a 2 year warranty). I connected it to my pc and played with it for a while, but later that day when I wanted to play with it again, there was 1 straight horizontal white line wherever there was a black background. I don't know how to explain it better, like, that line will show any color except black. Red, blue, gray, purple just anything is normal, even if there are more colors in that row, the white line would be visable only where it would be black.
So, can anyone tell me more about that, or even help me?

Can you make a photo of it?

check with this site, in which situation the line is visible:
https://www.eizo.be/monitor-test/

is the TV showing the line in the menu too?
Also check the TV directly with its own internet connection.

here's a video: https://vimeo.com/266885036
but now I realised it's on all colorus (more or less) except red...

ok yeah I ran the test on eizo, I have defective pixels on black, red, blue and green. But instead of a black line, I have a white instead

Return the device. It's obviously defective.

There most likely is a bad contact on the upper or lower portion of the screen. Sometimes it can be fixed by applying pressure on those spots (like sucking a piece of paper between bezel and the screen). But if the device is just purchased, then return it.
