iMac vertical lines

Vertical lines on an iMac display can be a symptom of various issues, ranging from software glitches to hardware problems. The vertical lines can be caused by software glitches or issues with the graphics drivers, loose or faulty display cables can lead to visual anomalies or a malfunctioning or failing graphics card may result in display abnormalities. If the iMac is under warranty, or if you have AppleCare, it’s recommended to seek professional assistance from Apple Support or an authorized service provider. They can provide accurate diagnostics and, if necessary, perform repairs or replacements to address the vertical lines on the display.
