A7 Screen Has Horizontal Lines. Problem: My A7 2017 earlier got it’s screen broken. Now I got new screen lcd combo which initially worked fine. But on 3rd day screen got dimmer ...

At that point the lines are almost invisible but it does mean using a much lower refresh rate than the default 60hz, making everything feel sluggish and choppy (terrible for games!).

Problem #1: Samsung Galaxy S4 screen showing greenish and horizontal lines. Just a heads up. I have no idea what update I am on. Though I do update when it says there is one ready to be installed.

I got a new 27" LG UltraFine 5K Display (27MD5KL) and I've noticed these strange faint vertical lines mainly in the center of the display. It's almost as if I can see the lines of pixels.

Another MacFixIt reader, Matthias, adds: "I also have the 'vertical lines' problem on my Macbook. It started after I applied the 10.4.7 update and seems to appear on every restart now.

“I just got the iPhone 14 Pro Max this past Friday(12/9/22). I noticed that when the phone wakes up, horizontal lines flash on the screen. It does that randomly, not every time the phone wakes up.
