? How to reset ClearType settings
many Windows users have been discovered and try to use the built-in system ClearType Text Tuner, its interface is shown below:


But then, I believe At the position shown in the second picture, many people were as dizzy as I was. After the adjustment, I found that the display effect was not as good as that.
How to restore it? This is a difficult problem. After some searches, including some foreign forums, most people have not found a solution. Some people say that they can be re-elected in a certain order. After I try, In fact, this still cannot be restored. Moreover, even if different monitors are connected to the same PC, the procedures and steps for selecting the clearest text may be different. (I am like this.)
How should I reset the settings? It seems that only analysis. With ProcMon, unsuccessful, the specific reasons have yet to be verified.

However, I hope that Microsoft will improve this tuner function in the next version of Windows, making it more practical and user-friendly.
