How to modify Win8 login interface DPI settings

With the development of display technology, the resolution of the screen is constantly increasing, and the display of 1920x1080 resolution has begun to become a general device. However, the default DPI for Windows systems is still at 96 DPI, which is not good for viewing text under high-resolution displays. 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, the DPI settings are the same as the resolution settings, which is a global setting. After setting, all users including the DPI at the login interface will be set to the value you need. Starting with Windows 7, the DPI settings have changed and the settings are only valid for the current user. How to modify the DPI settings of the login interface? You can do the following: 1. Adjust your current user's DPI settings to make it look right for your screen 2. Open the Registry Editor, navigate to HKEY_CURRENT_USERControl PanelDesktop, and find the DWORD value LogPixels , copy the value (in my case this value is 78 in hexadecimal).


Locate HKEY_USERS.DEFAULTControl PanelDesktop , create a new DWORD value, name it LogPixels , and assign it the LogPixels value of the current user you just copied (for example, my is 78).


At this point, the DPI settings for the login screen are complete. So can other users' DPI settings be changed together? The answer is yes, the operation is as follows: Search LogPixels in the registry, and change all the LogPixels values ​​with a key value of not less than 60 to the value of your current user (in me) Here, I need to change them to 78). This allows even new users to use the specified DPI without having to set it up.
What if I 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 96 DPI. The above settings also apply to Windows Server 2012, Windows Server 2008 R2, and Windows 7.
