i only see my GPU On "Display Adapters" on (Device Management)
a lot of modern systems with a dedicated GPU will disable the onboard iGPU.
so you will usually only see the dedicated graphics listed.
you may need to reboot using only the iGPU.
you may even need to select which to use in your BIOS if the dedicated card is still connected.
it depends on the specific CPU & motherboard.
i would just remove the dedicated PCIe card and launch the system using only iGPU.
but why are you worried about it?
