Did you install software drivers or Windows updates installed them?
The HP Omen has dual graphics, Intel and nVidia and it comes with the drivers installed and working from manufacturer.
The Intel graphics is used on daily usage but the nVidia GTX 1050 take over on demanding applications and games.
If you want the GTX 1050 to be the default GPU, then use 'nVidia Control Panel' to select the preferred GPU for a specific program.
