Swap Group
>
A swapgroup refers to a group of displays in a single system where all displays
in the group will update the displayed frame simultaneously. The term
swapgroup is also used to define an API interface within a graphics API, such as
OpenGL.

SwapReady
Swapready is a hardware signal created by the GPU used to synchronize a group
of GPUs so that all the GPUs in the group update the display image
simultaneously, regardless of how long each GPU took to render.
Synchronized Mosaic
>
Creates one large desktop of monitors and appears as a single desktop to the
operating system with all the monitors synchronized at the same time. This will
ensure no "tearing" across monitors on the setup.
For two GPU configurations with NVLINK, GPUs can share the sync timing
•
signal needed to synchronize Mosaic across the two GPUs. This helps
eliminate "tearing" when using two GPUs in the Mosaic.
For two plus GPU configurations, a Quadro Sync II card is needed to
•
synchronize Mosaic across all the GPUs.

Bi-level and Tri-level Frame Sync
Bi-level and Tri-level sync refers to industry-standard sync types for Standard
Definition (SD) and High Definition (HD) digital video, respectively, and
represents the start of a digital video frame. Bi-level and tri-level syncs are often
referred to as "composite sync". This term means that the sync and video data
are transmitted on the same video signal.
