By default, the Mac Dock is always visible, and that shouldn’t be a problem, but watch out! Because if you have your Mac connected to an external monitor, you might be in for a surprise.
There is a pretty ugly flaw, especially on IPS monitors, which leaves marks of images left on the screen for a long time, known as the “ghost image” effect.
Most of the time you don’t even notice the problem, but sometimes the glitch is so severe that it even interferes with your work.
It happens when you leave something static on the screen for a long time, for example when you are programming and spend several hours with the editor open and documentation next to it.
After a while, you close one of these windows and you can perceive the mark it leaves on the screen. It takes quite a while for this to happen, more or less depending on your monitor.
It is more noticeable on dark backgrounds, and if you have it in the middle of the screen as has happened to me, when you open another editor it gets pretty confusing between the real and the ghost image—in short, it’s annoying!
I already knew this and always try not to leave things too statically on the screen so as not to burn in the monitor, but of course, nobody remembers the Dock here.
The Mac Dock, as I mentioned at the beginning, is always visible by default, and yes! It looks nice, but it’s always there, in the same position and practically always the same image on the screen, so hello burn-in!
I found a solution for it. If you want to know how I did it, you can check it out in the following article:
