For the past 2-3 days I have been seeing a greyish bar on my M1 iMac's screen. After a few hours the grey bar starts to blink on & off, sometimes disappearing entirely but reappearing again after a 'wakeup from sleep'.
What exactly is happening here? And what can be done to fix this issue?
And yes, I did the obligatory restart/shutdown etc. but this grey bar still appears.

same here. Less than 2 years old. Extremely disappointed at Apple. Hopefully they proceed with a big global replacement program like they did with the AirPods Max.

After reading all the threads related to this issue, I've contacted Apple chat support and tried to negotiate a free repair for this widespread issue.
Apple chat support said that they don't have the authority to do this and ask me to contact phone support. Phone support said the same thing and asked me to take the iMac and go to Apple store. And Apple Store support said they can't do anything unless the issue appears in this Apple Service Programs list, and he suggested me to leave a message in Apple Feedback.
Everyone, please leave a feedback to make Apple fix the issue.
Mate, instead of repeating the standard stock answer where prob 90% stated is not applicable in any way shape or form, maybe you or someone else can actually help me to find a solution to my particular issue?
No, my computer screen is NOT turned off and no, the display brightness have NOT been reduced.
And I read someplace else there is no SMC reset for M1 macs.
There is a greyish bar on my turned on, display brightness on, 'non sleeping' M1 iMac screen.
If you or anyone else are familiar with the solution to this exact problem, can you tell me how to get rid of this please?
Same problem with my iMac Apple M1. Only a few years old. Just started a couple days ago. Very frustrating. Restart, upgraded software, etc. doesn't change anything. Come on Apple, please fix or replace. Obviously a common problem and faulty hardware.
Hi
Same problem here.
The largest topic about this was closed.
Persistent horizontal lines appear on iMa… - Apple Community
And, since this a user forum I don't see need to open more post about this.
But I Do have the same issue
Model: MGPD3CI/A
iMac 24-Inch 4 ports
And support says that since I'm out of warranty, it's not a problem that they can solve.
I also placed a bug report...
Let's hope some takes this from Apple.
This seems to be happening to a lot of M1 iMac owners. Within the 2 - 3 year mark of use. The only solution is a hardware repair. This is a hardware failure unfortunately.
There's not much you can do as it's a screen hardware problem (unless your're still under Apple Care).
The following topics illustrate the Silicon M1 iMac Display problem:
Being a hardware problem the only fix is to pay for a new screen and that is prohibitively expensive. If it gets too disruptive to use you could get an inexpensive 3rd party monitor to use and reduce the brightness on the iMacs screen.
If your Mac doesn't wake when you expect
Your Mac might pause a few seconds before it wakes up. If it doesn't seem to wake at all, check for these possibilities:
Your screen brightness might be turned down.
If you're using an external display, your display might be turned off.
Your Mac might be in safe sleep. To wake from safe sleep, press the power button.
Check for a sleep indicator light, if applicable, and make sure that your Mac isn't turned off.
If the previous steps don't work
These additional steps may help identify or resolve the issue:
Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
Try to isolate the issue by using another user account.

Pasandor,
Just a "heads up". Apple is the forum host, they do not read or participate in these user to user forums. If you would like to provide Apple feedback, please contact them at www.apple.com/feedback.
Same issue. No solution yet. Really sad and disappointed.
I have the same issue and Apple keeps deleting the posts that I am making regarding this
Same issue with my iMac M1 2021 version after using it for 2.5 years.
The other option is to use an external Monitor.:(
Looks like a graphics card problem. Have Apple examine it.
He's just trying to help and has no idea what you think is appropriate or otherwise.
You are free to ignore any post you feel is irrelevant or does not apply.
Good luck identifying your issue's cause.
