Blurry fonts in notebooks

So this is something I have partially encountered before (though I can't guarantee it will will work for everyone, or even anyone other than me), the first thing I did was to use this tool to fix scaling issues on Win10 (this is an external program, download at your own risk). There is also a possible option modification that may work for you:

  • Open Option Inspector (ctrl shift O)
  • Set to Global Preferences
  • Go to Formatting Options > Font Options > FontProperties
  • Set ScreenResolution to Automatic

Again, there is no guarantee but this is what I have used in the past.
