To Configure NVIDIA Driver Settings for Viz Engine, VGA mode

For maximum performance when running the Viz Engine in VGA mode, follow the procedure To Configure NVIDIA Driver Settings for Viz Engine, Video mode outlined above, and observe the following changes:

  1. In Global Settings, change the Global presets option to 3D App - Video Editing

  2. The parameter for Vertical Sync must be set to On

Vertical Sync

Notes for Vertical Sync:

  • Use the 3D application setting: Use for Viz installations (running in Standard PC (VGA) mode) and for Video Wall setups where video is in use.

  • Off: Used for Viz installations where video is in use (unless used for video walls).

  • Unified Back Buffer: Must be disabled (Off) in any case. Note that this depends on the driver version used. Most recent drivers from NVIDIA already have this setting disabled.

  • For Quadro FX 4500 SDI, and FX 5500 SDI boards the parameter use_old_nvsdk may need to be set to 1 in the Viz Config file, if stability issues encounter, on unsupported systems.

To Configure the V-phase Settings when Synchronizing the Card

  1. Start Viz Config, or open the configuration from Viz Artist (Config button in the upper right corner)

  2. Select Video Output.

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.

Make sure that the G-Sync card firmware is version 4.0 (0x54 in the NVIDIA Control Panel (System information)). To check the current version download these files from ftp.vizrt.com:

  • start_update.bat

  • NVGSyncUpdate.exe

This section contains the following procedures:

To Check the Firmware Version

  • Double click the start_update.bat file:

    • If the output says 4.0 same version, no action is required

    • If it shows an older version install the latest version

To Install the Latest Firmware Version

  1. Close all applications, including the NVIDIA Control Panel.

  2. Run NVGSyncUpdate.exe -u.

  3. Restart the machine.

  4. Check that the version is 4.0 (0x54 in the NVIDIA Control Panel (System information)).

To Configure G-SYNC on one Viz Engine

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

    images/download/attachments/27018751/graphicscardreference_gsync-server1.png

  2. In Workstation, click Synchronize displays.

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

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

To Configure the G-SYNC Card on Viz Engine Slaves

Do this procedure on each Viz Engine slave.

  1. On the Viz Engine slave, open the NVIDIA control panel.

    images/download/attachments/27018751/graphicscardreference_gsync-client1.png

  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.
