Frame Synchronization

Frame synchronization is the process of synchronizing display pixel scanning to a synchronization source. When several systems are connected, a sync signal is fed from a master system to the other systems in the network, and the displays are synchronized with each other.

NVIDIA frame synchronizing technology involves two main processes:

  • Frame lock synchronizes applications across multiple displays or windows. Frame lock allows the display channels from multiple workstations to be synchronized, thus creating one large “virtual display” that can be driven by a multisystem cluster for performance scalability.

  • Genlock (also known as “house sync”) synchronizes one or more systems to a common sync source. Genlock allows the graphics output to be synchronized to an external source, typically for film and broadcast video applications.

The following NVIDIA products support frame synchronization:

  • NVIDIA Quadro FX 3000G

  • NVIDIA Quadro G-Sync combined with NVIDIA Quadro FX 5500 or 4500.

  • NVIDIA Quadro G-Sync II combined with NVIDIA Quadro FX 5800, 5600, 4800, or 4600.
