Sorry for the title gore. But it’s the only way to let people know that all four of these laptops are identical.

These laptops come with an HDMI port and a Mini DisplayPort. Here’s how to get both working simultaneously so you can have three screens.

Three monitors.

Enter the Dragon BIOS

  • Restart your laptop.
  • Press the F2 key when the manufacturer logo displays.
  • You’re now in the BIOS.
  • The screens may look different from mine.
  • Enter the Setup Utility BIOS screen.
  • Select Advanced Options in the BIOS.
  • In “Advanced Chipset Control” go to “DDI Control” and set “DDI to mDP”. That puts the Display Digital Interface to the mini DisplayPort. Thunderbolt config.
  • In ThunderBolt Configuration, set the “Security Level” to “Display Port Only”.
    Display port config.
  • Save and Exit. Your computer will reboot and Linux will be able to see all the monitors.

I hope that’s of some use to you!
