While playing video games or viewing videos, you may experience the following issues: Low video frame rates (Frames Per Second = FPS), video frame drops, low video resolutions, or pixelated video
The integrated IntelHD video card option is being used and not the discrete AMD or Nvidia video card option that can offer better performance.
Some Dell laptops have two Graphic Processing Units (GPU) built into the laptop. The primary is the Intel integrated GPU (built in the processor) and the second is the discrete AMD or Nvidia GPU.
The purpose of having two GPUs is to extend battery life in laptops and to have better graphic performance for gaming, programming, and so forth.
The best example is when using the laptop on battery, the integrated Intel GPU is used since it uses less power. But if the laptop is plugged in and you want to use the laptop for gaming, the discrete GPU would be used for better performance.
Some Dell desktops have the option to add a discrete video card for better video (games, 4K video, and so forth). When an external monitor is connected to this discrete video card, there is no option to use the integrated Intel GPU.
Default Settings
By default, Windows defines the best GPU for each application based on preloaded profiles. Applications with specific GPU requirements show a Lock icon beside the application name and cannot be changed, these applications always run on the Integrated GPU (Power-Saving Mode).
Manual Configuration
The following steps can be used to set the AMD video card as the default video option.
In the Switchable Graphics menu, the Running Applications view is displayed by default. This view lists recent and current running applications and their assigned Switchable Graphics mode.
For applications that are not locked by Windows, the following Switchable Graphics modes can be selected from the application drop-down menu:
Select a desired mode for the application and the change will take effect the next time the application is loaded.
If an application is not on the list, do the following:

Resolution and Scaling in Nvidia
Your Nvidia video settings may cause issues with resolutions and scaling when loading video games. These settings help:
Newer Intel processors (CPU) have an integrated video processor (GPU): Intel - What Is the Difference Between Integrated Graphics and Discrete Graphics?
Nvidia Optimus is a computer GPU switching technology by Nvidia. Depending on the resource load from the client software applications. This will seamlessly switch between the two graphics adapters within the computer to provide either maximum performance, or minimum power draw from the computer's GPU.
