Is it possible to say... put together a few virtual servers with multiple GPUs that will virtualize around 18 PCs and then assign them around 4 monitors a piece by assigning each virtualized computer one of the GPUs?
Trying to put together a simulator type trainer using as little computing hardware as possible but keeping the numerous monitors. The monitors are touchscreen and essential.
you might be better off buying multple thin clients than gpus.
you would also have to support multiple kyeboards and mice per host...
thin client is the middle option I think,.
