I have a notebook with an Intel UHD 630 and a GeForce GTX 1050 4GB GDDR5
I want to turn off the internal graphics and use the GeForce as a graphics card for the internal monitor
You can set this in the Nvidia control panel,
Go to Control Panel and then to Nvidia Control Panel
then when it is open on surround and pysix
there in PhysiX settings, select the option Automatic on your graphics card GTX1050 so the GPU of the processor remains inactive and the laptop only uses the GTX1050.
if you have NvidiaGeforce Expiriance this is actually unnecessary as it recognizes games and selects the right card for you
In most cases this should happen automatically. Otherwise just set it in the Nvidia control panel. Or right-click on applications and select the option "Run with Nvidia high-performance processor".
