Had multiple MSI Prestiges and the image retention / ghosting is a nightmare. It always got hot and so the retention got worse. Even though it is the same panel, I recommend the LG. Didn’t have any retention with that. But the monitor needs to be turned off when you want to sleep. The Mac keeps waking it up. And sometimes I need to disconnect and connect the Thunderbolt cable as it doesn’t wake up anymore. Happens twice a month.
Other than that, very happy with it.
