Hello,

 

the 2 garphicscards are a joke . In the true the laptop dont have a real secound graphic card . The problem is you have a real Intel UHD graphic embeddet in the system and the secound Nividia is only a GPU extensions thats works always with the Intel UHD . Its only a extension like a extra RAM Modul in the Notebook. The most think when read they have a real big nvidia Graphiccard inside . But its only a extra chip from Nvidia thats works with the Intel UHD and help when the UHD Intel needs more power. 

The Nvidia is only for some 3d options and sharpness avaiable. In 2d the nvidia is not working. So its only working with the Intel by some 3d apps and operations. Becuase this is not possible to work alone with the nividia. Its a bad Advertising to get customers pay more for only a bit more power. Overall when you dont play any games you dont get nothing and you will notice in games to that the nvidia is only working a bit. On the end you have pay nearly 3000 EUR for a notebook with a cheap intel uhd engine thats build in the Intel framework.

Hello there, Just stumble on this topic now. 

Windows switch the graphic to the igpu to save power. It should automatically switch to your dgpu when you game, etc.

You can try to use your NVIDIA gpu by opening the NVIDIA control panel, go to the manage 3D settings > Global settings then select the High Performance NVIDIA processor in the preferred graphics processor.

 

Hope this helps!
