Horizontal black lines on my iMac 2021 24" screen

Since a year ago my iMac 2021 14" started to show horizontal black lines at the bottom of the screen, now after a year the black lines grow bigger reaching now at least 25% of my screen. My iMac is up to date in software ... I see no solutions on the forums. Since this is an iMac I cannot easily replace the display.. I need solution from APPLE ... help!

iMac 24″, macOS 15.0

IF you did not purchase AppleCare then you decided to self insure. Apple does not have a repair program for 2021 iMacs so you can either get rid of the computer or take it to your local Apple Authorized Service Provider to have the display repaired. If you are in the USA, the quotes I have seen are in the $700 range. If Apple does introduce a repair program then you may qualify for a repair refund.
