Mosaic and SLI Mosaic
NVIDIA® SLI® Mosaic takes the multiple GPUs in a Quadro Plex Visual Computing System (VCS) or a dual SLI-capable Quadro configuration and presents them as a single logical Quadro GPU to the operating system.
NVIDIA® Mosaic Technology takes multiple displays and Quadro or NVS GPUs and presents them as a single logical GPU to the operating system. Unlike SLI Mosaic, NVIDIA Mosaic does not offer the synchronized multi-GPU output required for stereoscopic or multi-projector installations.
Either way, you can use multiple displays to create a larger virtual canvas.
