Came across the following related to the behavior of graphic cards in laptops/desktops.
my system have both integrated intel graphics and also Nvidia graphics card and I was under impression that I am using the Nvidia graphics card but later realized that most of the times system is using the Intel graphics card .
After some research found that the Nvidia graphics card uses its “Optimus Technology” to switch between the integrated intel graphics with Nvidia graphics to save the battery life.
Based on above , never be able to use the Nvidia graphics unless you play 3D games or connecting to external desktops ..etc (Offcourse there is way you can specify which programs can use the Nvidia but still screen will always uses the intel graphics)
I have disabled the “Nvidia Optimus Technology” in BIOS settings as Nvidia graphics has dedicated RAM and I will be on the power cable most of the times instead of on battery to get most out of the Nvidia graphics card.
