I bought a iMac (Retina 5K, 27-inch, Late 2015) it was great for a couple of years, but now it started to show ghosting on EVERY screen . if I leave a screen unattended for a while, sometimes it is impossible to read the screen, I cannot be the only person with this problem, help me please if you have a fix
iMac 27″, macOS 12.4
What happens if you boot your iMac into Safe Boot mode? Does the ghosting effect remain? On normal reboot, is it resolved? Reset the System Management Controller (SMC)? Any software or drivers that you installed just prior to the ghosting effect?
If you cannot resolve this issue with the above, then I suggest…
Contact the nearest Apple Store, or Apple Certified Service Provider to schedule a diagnostic appointment. As fellow users, we cannot resolve Mac hardware issues that may require service.
As a test, set the display to sleep after 5 minutes or less in the Energy Saver preference and see if that helps.
Then have look at > Avoiding image persistence on Apple displays - Apple Support to see if anything there helps.
