Horizontal Lines on Screen of iMac, 24", 2021

Just got the same issue today. The horizontal lines are flickering near the bottom of the screen. It is not much of a bother for now, but I'm worried that the issue will become worse soon.

I bought my iMac in 2022, thus the issue popped up after 3 years of frequent daily use. It is a bit longer than others. I'm not using Auto Brightness, and the Brightness level is relatively low all the time.

Just posted as we are on the same boat 🤞, and looking for a feasible solution from Apple.

Apple keeps removing my comments about my situation but here’s the bottom line:

They declined my claim for support and didn’t recognize the widespread problem and confirmed that they are right to charge for the screen replacement. Pretty sad since I’m having headaches and seizures from using the computer with this problem…

The reason your posts are removed is because you continually are violating the Terms of Use that you agreed to abide by! You can find them at the bottom of this web page by clicking the link, please read them and you will see what you can and cannot post on these forums.

If you are unhappy with your iMac, Apple or anything associated with Apple of course you can select other devices and manufacturers. But please do look over the Terms of Use so you have a good understanding of what we are and are not allowed to post on these forums.

I had this problem, now the screen doesn't work anymore, the screen has gone black at the bottom, you can't see anything... it's unusable now. This is called "planned obsolescence", it's not acceptable by the Apple brand.

This must surely be an extended Apple service program.

The horizontal black lines have started to show up persistently on my iMac today, after 4 years of occasional use. It started showing up about 1 year ago, but would go away after a restart or shutdown, or just disappear by itself. I typically use my LCD at 50% brightness or less.

I have called Apple to request for a repair and waiver of repair fee, they had not agreed to it yet, but asked me to bring it into a service centre.

I am respectfully requesting Apple to address this issue, as Apple devices are typically quite reliable.

Apple personnel, i.e. engineers, are not in this forum which is a user to user forum. We're all end users like yourself. The only way to directly address Apple is via iMac Feedback.

I am experiencing the exact same issue. Check out the bottom of my screen (image)
