Vertical greenish lines dark screen

[toneLA2]

Hi all,

Are these vertical pixel lines normal on the retina screen?
Noticed that on a dark background. It's a new machine in exchange of the one I brought them at the genius bar today.

What's up with that? LG panel - 15-inch 😱

As with your other rMBP, take it back.

I'm about to. But my question was 'what is that?' It was totally black on my Samsung panel. Looks like a rainbow from left to right with these rather pronounced lines going up and down mostly on the left. 😡
