Synchronization

Visual computing applications that involve multiple displays or even multiple windows within a display can require special signal processing and application controls in order to function properly.

For example, in order to produce quality video recording of animated graphics, the display graphics must be synchronized with the video camera. As another example, applications presented on multiple displays must be synchronized in order to complete the illusion of a larger, virtual canvas.

The NVIDIA Quadro G-Sync II option card and Frame Synchronization software lets you synchronize windows and displays for various visual computing applications.

Unpacking

Prior to unpacking your new NVIDIA Quadro G-Sync II option card, it is a good idea to make sure you meet all the system requirements (page 3) for a smooth installation.

Be sure to inspect each piece of equipment shipped in the packing box. If anything is missing or damaged, contact your reseller.
