G780 doesn't allow switching between Intel and nVidia graphics drivers

Hello together,

I'm currently struggeling to change the graphics driver of my Lenovo G780 Notebook.

Until now, everything is running via Intel Onboard Graphics and i can't switch to the nVidia card. (See Screenshots)

Additionally i can't even set the usual options in nVidia System control panel, there are only 3D-Settings...

As you may already know, the G780 has only one physical VGA-Output, but the control panel shows two of them Smiley Surprised

My drivers are all the recent ones and updated... 

 

Did someone experience something like that in the past?

I'm even open for highly programming-focused answers (I'm a tech guy myself but this is quite hard to solve).

Thank you already now for your answers Smiley Wink

Hi there, Gamer          -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

There are two sets of graphics card in the Y700, one is the integrated intel GPU and another discrete is the Nvidia, which one is used depends on graphics load and your preference. So at idling the Intel gpu kicks in. 

you can force the discrete GPU (the Nvidia GPU) to run all the time, by going to bios and set it to discrete graphics mode. But this will draw more power and produce more heat, however the graphics performance will be higher.

Technically, the Intel integrated graphics is always active, although it is not always in use. Nvidia graphics will turn on and off according to need. Software from Nvidia called Optimus automatically switches between integrated (Intel) and dedicated (Nvidia) graphics, according to the application.

 

The easiest way to see which graphics card is in use is to check the "Display GPU activity icon in notification area" option in the Desktop menu of the Nvidia control panel. It should automatically use the Nvidia graphics card when Steam is running. If it does not, you can add Steam to the program settings in Nvidia control panel and select that it should always use the Nvidia graphics.

 

Update us how it goes.
