Default Notifications DPI settings

Hi,

I want to change the screen resolution of notifications to a less larger screen so more text will fit on the screen.
I'm on NULL_23 and have Xposed App Settings installed.

I tried changing the "messages" to different dpi setting, but it stays the same.

Anyone know how I need to set the dpi settings ?

EDIT : Never mind, I was on the correct path with the Xposed App Settings but ofcourse I need to enable the module otherwise it won't work
