Question Will you still get output video if you switch an i7 with intergrated GPU to a CPU without an intergrated GPU, even though the

Good day all,
I have an Acer 7600U AIO that has issues with having both the Intel i7 GPU and the onboard Geforce GPU, under Windows 10. If a non GPU equipped CPU was installed (I know it's balled), would the system still output video? I think the way the system architecture is set up all the video (even from the Geforce) runs through the i7 GPU. I can theorize on a basic "physical" level that this would be an obvious no since omitting the GPU unit of the CPU would terminate video at this point and no video or errors would occur. Although this could be totally differnt to my simple and myopic view. Maybe there is circuitry that allows the pass through of the Geforce GPU regardless of the Intel i7 GPU.
Acer has been no help in correcting the drivers needed to allow both GPUs to work under Windows 10 and it is a driver issue. You can follow the long thread here

The only way to get Windows 10 to install and be stable is to disable the Geforce GPU. Unfortunately one cannot totally disable the Intel GPU (even if you disable it under DM so that is not a simple option). Every method has been tried by true PC professionals, Acer and Microsoft techs to everyday PC enthusiest and nothing has worked, without disabling the Geforce GPU. That is not an option for such a high end AIO that we all paid dearly for.

The graphics chip on the Intel APU is required by/used by the system for boot display, Windows Desktop display and all the usual Windows tasks that you run which don't require the high-performance Nvidia/Geforce graphics processor.

The high-performance Nvidia/Geforce graphics processor is reserved for gaming and graphics software.

So if you swapped out the Intel APU for a regular CPU, you would see nothing on the screen.
