Hello, your notebook has two video cards - one is integrated in CPU itself and second is discrete - NVIDIA GeForce GT 940M. Technology which is trying to find the best compromise between battery life and performance is called NVIDIA Optimus - http://www.geforce.com/hardware/technology/optimus/technology.
When less critical or less demanding applications are run, the discrete GPU is powered off and the Intel IGP handles both rendering and display calls to conserve power and provide the highest possible battery life.

You can use NVIDIA Control Panel to set default preferred GPU - for best performance and to use discrete GPU by default change the combo box '''Preferred graphics processor'''to your GT 940M (see pic. below).
