A few minutes after I turn on the macbook, my display ghosts very much. Does anyone know why?
Here’s an article about the issue: Avoiding image persistence on Apple displays. And some temporary fixes. Most of the time a new display can fix the issue.
I’ve had this problem too on a late 2013 iMac, and I recently discovered that one thing that seems to get rid of the ghosted windows almost immediately is using f.lux to switch to darkroom mode. I tried that on a whim after restarting didn’t work and the ghosted windows vanished, even after switching back to normal mode. Maybe worth a shot!
Have you tried SMC and NVRAM reset if after doing this you are facing an issue then there is a logic board or display error.
appears to be a software-hardware issue. not monitor. As I have 2 MacBooks and switches displays. one does it the other does not do this ghosting. 1 MacBook is newer and that was has the issue. This is when for external LG 5k display only. internal laptop display is ok.
I had the exact same problem, Apple took back the laptop and provided me with a note that it was not repairable. The shop provided a new one, quickly thanks to the helpful note Apple provided.
I have yet to try this but many claim it works. I would just add to this that you may need to let the screen saver run at least overnight initially. Not sure if it matters but I would go with the one they call flury. https://support.apple.com/en-us/HT202580
