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? -dsr-
