[SOLVED] How do I know if an HDMI port on my laptop connects directly to the dGPU card and not the integrated graphics?

Hey, so i have an Acer Nitro 5 (an515-55-76xc) 2020 model and i wanna know how to disable Nvidia Optimus? Where and how?

Also, is my HDMI port connected directly to dGPU or not?

Thanks

Both the dGPU and the CPU are components on the mobo and neither one has an HDMI port connected directly on them.
You choose by bios or with the driver (in your case optimus) which one you want to use for each work case.
In windows 10 there is also an option in the graphics settings where you can choose which GPU to use for each software separately.
