NVIDIA G-SYNC Card

The G-SYNC card makes sure that all screens, which make up a Video Wall, are synchronized. When there are several Viz Engines in use, one is defined as the master and all the others as slaves. Pascal GPUs and higher require a gSync Gen2 version.

Make sure your gSync is running on the latest firmware:

Generation

Version

Quadro Sync 2

2.02

Quadro Sync

7.01

To Configure G-SYNC on one Viz Engine

  1. On Viz Engine, go to the NVIDIA control panel.

  2. In Workstation, click Synchronize displays.

  3. In The timing server is..., click On another system.

  4. In Select displays to lock to the server, click each available display, in the field below, to make them active.

To Check the G-SYNC Status

  1. On each machine, in turn, open the NVIDIA control panel.

  2. In Workstation, click View system topology.

  3. On the slave system, make sure that Frame lock sync pulse is present shows in the G-SYNC status portion on the lower part of the screen.

Genlock (House Sync)

There also the option to use a genlock (house sync) signal from the studio as an input to the G-SYNC card. In this case, once connected, check the signal in the View system topology screen, in Workstation. House sync signal is not present (1) means that no external genlock is connected and that the pulse is generated internally. If the external genlock is not used, this message can be ignored.
