This action overrides any refresh rate that you may have selected from the refresh rate list.

Click the Sync Edge list arrow and then select both leading and falling edges.

Detecting the Incoming Signal Type

Quadro G-Sync II supports the following external synchronization signal types:

¾TTL (3.3 volt level)

¾Composite Bi-level (NTSC or PAL sources use bi-level composite signals)

¾Composite Tri-level (HDTV sources commonly use tri-level composite signals)
