Is it an inherent flaw that all LG panels dating back from late 2012 iMacs to the new models including the iMac Pro all suffer image retention/persistence/ghosting? I noticed my late 2012 iMac 27", returned iMac Pro, and current iMac Pro with upgraded RAM seem to all be affected. I can easily reproduce small signs of this from normal usage from simply browsing the web for 5 minutes or more with my dock shown and shortly spot very subtle outlines of my dock icons at the bottom after opening Final Cut Pro in full screen mode. I have found multiple users experiencing the same issue on other iMac models online and I just want to know if this is normal to have. I want to get a definitive answer as I keep finding mixed answers with some stating its normal and apart of the technology, while others reporting it a defect that shouldn't happen. I'm worried later down the line the ghosting effects will get worse and I would hate to have to visit the Apple Store for this issue so soon, especially after spending over $8,000. Only had the machine for 1 week.
