How to alter the DPI for all users

Updated: October 13, 2009

Applies To: Windows 7

This article applies to the following operating systems:

  • Windows® 7


One is unable to change DPI for all users.


With Windows 7, DPI is set per user. Despite DPI being set on a per user basis, you can alter the global DPI setting. The global setting has higher precedence than one set for a user.


Log on as administrator and modify the following registry value.

This does require a reboot.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\Current\Software\Fontsset LogPixels=dword:<your desired DPI>
