The effect of showing the previous image on a Retina display against the background of a newly opened image is not unique to computers with this type of display.
Image retention can be seen on all LCDs, regardless of manufacturer. You shouldn't worry too much about it, as you don't need to run to the service to get your iMac or MacBook Pro repaired.
Image persistance effect
This is the name given to this effect in English. In the technical literature, you can also find the term image retention, which, in fact, means the same thing. Often a residual picture can be observed with the login window of the system if it has been open for a long time. After entering the password, this window remains visible against the background of the opened desktop of the operating system.
Apple: Your computer is fine
According to the specialists of the "apple" corporation, there is no need to hand over your Mac for warranty repair if this phenomenon is detected. Unlike cathode ray tubes and plasma panels, all LCD displays created using IPS technology have this disadvantage. However, image retention does not affect performance in any way and will not affect it in the future. LCDs do not fade, unlike CRT monitors.
How to deal with the effect?
At the moment it is impossible to get rid of the afterimage on the monitor, but you can try to reduce its visible consequences using mac OS tools. For this, the operating system has special functions. By default, they are always enabled, but when configuring the computer, the launch period could be changed or removed by the user himself.
Enabling this feature not only removes the residual effects of images, but also conserves power or extends the drain on your Mac notebook battery. The response time can be set based on how often and for how long the computer stays on but is idle. The function is enabled and configured in the following order:
You need to go to the System Preferences - > Energy savings . This can be done via the top left menu on the desktop.
The Monitor Sleep slider must be moved to the required amount.
For laptops, this parameter should also be set on the " Battery " tab - this will extend the battery life. It is also worth turning off the screen saver, which also consumes battery.
Owners of MacBook Pro and iMac with Retina displays, Apple Thunderbolt Display and Apple Cinema Display are likely to experience this effect. It is absolutely safe for the computer and does not affect the lifespan of the monitor. You can get rid of it by shortening the period of displaying a static image on the screen, for example, by setting the time to enter sleep mode.
