Display.displays only shows the first display in editor

Hey all,

In editor Display.displays only returns 'Display 1' as an activatable display, even when I have a camera active on the second display. When I build unity and run as standalone it will detect both of my monitors as it should, the issue is only in editor.

Is there a setting hidden somewhere that I'm missing or something that I need to call prior?

Edit: I'm on 5.4.0f3
