Is it realistic to render a super-high resolution image over an array of 3 by 3 or 5 by 5 (for example) stacked screens? Could I do this by combining several different GPUs, or would the only way be to use a GPU per screen and simply divide the image to be rendered?
Ideally I'd like to be able to use fewer GPUs than screens. Even though one GPU is insufficient I'm hoping I won't need n GPUs for n screens.
If this is possible I'd also need to know whether this requires using the same make and model of GPU or whether unrelated ones could still share processing.
