Modify the DPI setting method of the login interface of Win 8 system

Opening message: With the development of display technology, the resolution of the screen is constantly improving, and the display of 1920x1080 resolution has begun to become a general device!
But the default DPI of the Windows system still stays at 96DPI, which is in high resolution. The effect of viewing the text below the monitor is very bad; I believe many friends have manually adjusted the DPI, but like me, you may have doubts about the DPI settings of the login interface: Why is the default 96DPI? In Windows Vista, DPI settings Like the resolution setting, it belongs to a global setting. After setting, all users including the DPI at the login interface will be set to the value you need. Since Win 7, the DPI settings have changed and the settings are only valid for the current user.
The following is the method to modify the DPI settings of the login interface
1, adjust your current user's DPI settings to make it look suitable for your screen 2, open the registry editor, navigate to HKEY_CURRENT_USERControl PanelDesktop, find the DWORD value LogPixels, copy the value (in my case this value is 78 in hex).
2, locate HKEY_USERS.DEFAULTControl PanelDesktop, create a new DWORD value, named LogPixels, assign the value of the LogPixels of the current user you just copied (such as my 78).
3, at this point, the DPI setting of the login interface is completed.
Other users' DPI settings can also be changed. The specific operation method is as follows:
1. Search for LogPixels in the registry, and change all LogPixels values ​​with a key value of not less than 60 to the value of your current user. (In my case, I need to change them to 78). This allows even new users to use the specified DPI without having to set it up.
2, what if you don't want to use it? Just change all the LogPixels key values ​​in the registry with a key value of 60 or less to 60 to restore the default 96DPI.
Conclusion: The above settings also apply to Windows Server 2012, Windows Server 2008 R2, Win 7. You can try it yourself!
