The display cache on Windows 10 helps the computer to remember which mode and resolution to use when a particular display output is detected by a connected external monitor. This eliminates the need to manually reapply all settings each time a particular external monitor is connected.
Sometimes the cache may have problems and you notice that the display output does not work properly when you connect to an external monitor.
In this case, you can reset and clear the display cache to see if this solves the problem. When you reset and clear the display cache, Windows 10 is forced to forget all connected external monitors and their individual settings that are stored in the computer’s display cache. The next time you connect to an external display, it will be treated as a newly connected display with the default and optimal settings.
In this tutorial, you will learn how to clear and reset the external display cache under Windows 10.
Clear the display cache in Windows 10
To do this, you must open the registry editor. However, before doing so, we recommend that you first create a system restore point or back up your registry.
Once this operation is complete, navigate to the next location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

CONCLUSION
Caching is used to improve and accelerate application performance and operation. But at some point, the cache is corrupted or damaged, so in this case, we have to empty the cache so that there is no impact on our system. Because this corrupted cache can make the system boring and stable. It takes much longer to perform an action, whether it is opening a file, visiting a web page or such an action. Therefore, you should empty the cache from time to time to get fresh and intact data.
