Hi there,
Connect the monitor to the
laptop's 15-pin video connection on the back of the computer
Once connected, your laptop may automatically switch
to the new external display or you may be required to press
a sequence of keys in order to switch from the laptop to the external display
For example, often either Fn + F3, Fn + F5, Fn + F8, or Fn + F9
is pressed to switch between alternate displays
depends on the model
Thanks
