Faint pixel thick vertical lines on Apple Cinema Display 27"
I bought old used a1316 Apple Cinema 27” Display to connect to my 15” MacBookPro (Early 2013) and just use both at home mostly for browsing and movies.
Today I noticed faint pixel thick lines about inch from each other all over the screen. Clearly visible on dark backgrounds when MacOS is in DarkMode, but almost impossible to see if screen is completely black or white.
Screen on macbook is fine. I played with different resolutions, reset PRAM, rebooted machine, tried different thunderbolt connectors…
So far, if I’m far enough from the screen it’s not bothering me much. But just wanted to know is this is something I need to worry about? Can the condition of the screen deteriorate?
I made a photo of the screen, not sure how visible issue will be:
Thanks in advance!
