Chosen Solution
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!
Your display uses LVDS signaling so it can encounter noise issues either within the LVDS cable or its connections internally. Another source of noise is aging noise clapping capacitors on the logic board. At this point if you can live it I would. If it really is bothering you, you could try fixing it but the likelihood of solving it without major parts replacements is not likely.
