How to change screen resolution on Windows Server 2008 Server Core

Since Windows Server 2008 Server Core doesn't have access to display properties, you must change the screen resolution using the registry. Here's how:

  • Log into Server Core with an admin account
  • Run Regedit from the command prompt and modify the following reg keys:
HKLM\System\CurrentControlSet\Control\Video
  • There, you will find one or more GUIDs. Expand each one to find the one with a VolatileSettings subkey under the 0000 subkey (usually the first GUID)
  • Double-click the 0000 key and modify the DefaultSettings.XResolution and DefaultSettings.YResolution values to set your resolution
  • Close Regedit
  • Logoff and log back on to receive the new resolution settings
