I currently have a second monitor attached to laptop. It is set at Display 1, because the laptop screen is tiny. However, if I fail to return the laptop screen to Display 1 before I disconnect everything and take my laptop somewhere, then when I open laptop, there is nothing on the screen... if I right click for properties, the option box opens on the other, not-there monitor. Any troubleshooting I can do without reconnecting laptop to another monitor? Is it just bad practice/habit to make the second monitor the primary display?
