I am suddenly starting to see this faint horizontal line in 3/4 of the screen and the Dock area, especially on dark colors and blue. They don't appear when I connect to an external port via a thunder bolt.

Faint Horizontal line in 3/4 of screen enter image description here It's just over a year old :( What could be causing this?

    That indicative of an LCD display failure. More than likely, it has to be replaced.

Sounds like a hardware failure, you should go and visit an appleStore or a apple reseller to get this problem fixed.

I had the same Problem, so I went to the appleStore in Oberhausen (Germany). they repaired the Display for free.

  • That's what I was scared of, don't know if they would have any such policy here. Apple support in India sucks. Jul 18, 2018 at 5:48
  • Just ask. I Don't think that there will be a problem.
