Mac terminal font changes on external monitor

I have a Dell U2412M Monitor that I connect to my 2015 Macbook Pro with a DVI to Thunderbolt connector.

When I open and view the Terminal on my laptop's screen, the terminal looks like this:

laptop terminal

This is how I want it to look. Specifically, it uses Monaco as the display font. However, when I move the same terminal window over to my external monitor, it looks like this:

external monitor terminal

The font has completely changed.

Why?


I solved it this way:

  1. Go to Terminal
  2. Preferences
  3. Profiles (select your profile)
  4. Text
  5. Check Antialias text

Check antialias text option
