Flickering screen - bottom half only

I have a iMac desktop running latest Sequpia V15.7 and the screen has started flickering. Bottom half only. Have tried rebooting several times, and updated to latest Sequoia version. Any next steps?

iMac 24″, macOS 15.7

Display artifacts can be caused by software or hardware issues. Take a screenshot (Command-Shift-3) and if the issue on the display does not show up in the screenshot, the most likely cause is a hardware problem with the display (cable/panel/etc.). In that case, the next step is to contact Apple for service.
