MULTI-GPU MOSAIC CONFIGURATION 

MOSAIC OVERVIEW 

Mosaic is a technology that combines multiple displays or projectors into a single virtual 

display. It’s cable of creating a projector overlap region or subtracting the area behind 
screen bezels to create a single unified display surface. With Quadro Sync and 
supported Quadro GPUs up to 16 displays can appear as one to the operating systems 

and any application that runs on them. The image in Figure 3 is an example of a 3 × 3 
display wall connected to 3 Quadro K5000 graphics boards. 

 

Figure 3. 

3 x 3 Mosaic with Quadro Sync 

When working with multi-GPU Mosaic, Quadro Sync automatically keeps all the 
displays that are part of the Mosaic synchronized.  

For more information on Mosaic refer to the NVIDIA Web site at
