Each monitor will only use the GPU that it is connected to.

If you are using a GPU-as-coprocessor system like CUDA or
mlOPEN, that GPU is generally not available to be used by a
monitor at that time. It may be used before or after that.

If your motherboard has monitor outputs, it may be controlled
by:

- a motherboard-integrated GPU (not a card)
- a motherboard-integrated video controller (also not a card)
- a CPU-integrated GPU (Intel desktop CPUs, AMD APUs)

It will not be controlled by a plug-in GPU.

Finally, there are game APIs which use multiple GPUs to do the
rendering of screen images and pipe it through one final GPU
output; that is called AMD Crossfire and NVidia SLI or NVLink --
none of these are compatible with each other, and they are all
likely to be de-supported in the near future.

Does that help explain things?
