I m seeing horizontal lines on the display, I treid Comman + Option + P + R but that doesnt come upto second apple sound. I tried shutting down my Imac and start after 15 seconds of unplugging the power cord.
If I take the screen shots,and airdrop onto my phone, there are not horizontal lines.
Is there a hack to solve this please?
Thank you

Only GPU failures and glitches can be captured by a screenshot.
Display failures and anomalies can be captured with a photo, but not by a screenshot.

Nope' The display panel problem needs to be addressed and serviced by Apple.

You can't reset the PRAM of a Silicon iMac. It sounds like you need to have Apple take a look at it.
