-> click on 'Customize...'
-> check ' Enable resolutions not exposed by the display'
-> click 'Create Custom Resolution...'
-> ensure all projectors are checked
-> Horizontal pixels: 1280 Vertical lines: 720 (for 410S and earlier projectors) or 800 (for 500S projectors) Refresh rate: 120
-> click on 'Test'
-> confirm the resolution works
-> ensure all projectors are set to the new custom resolution
3D Settings > Manage 3D Settings
The following stereo and render settings are recommended by WorldViz for VizMove projection systems.
⦁ Anisotropic filtering: 4x
⦁ Antialiasing FXAA: Off
⦁ Antialiasing Gamma Correction: On
⦁ Antialiasing Mode: Override any application setting
⦁ Antialiasing Setting: 8x
⦁ Antialiasing Transparency: Multisample

Workstation > Synchronize Displays
Note: The Synchronize Displays option is only available when GPUs are connected via G-Sync cards.
When working with multiple GPUs, the timing signals across all GPUs in the system need to be synced in order to get stereo working across displays. Each Nvidia Quadro card has a G-Sync option card that it’s connected to via a ribbon cable. The G-Sync cards are daisy chained together via standard CAT5 cables plugged into the external RJ45 connectors. The following is a warning from the Nvidia documentation:
Note: WARNING! The voltage and signal on the frame lock ports are different from Ethernet signals. Do not connect a Frame lock port to an Ethernet card or network hub. Doing so can cause damage to the hardware.
Single machine system:
Under The timing server is, click the On this system radio button. Select the checkboxes for all displays showing 3D content to add as clients and then click Apply.
Multiple machine system:
The timing server is the machine that’s connected to the 3D glasses emitter. On that machine under The timing server is, click the On this system radio button. Select the checkboxes for client displays and then click Apply.
On all client machines, under The timing server is, click the On another system radio button. Select the checkboxes for client displays to lock to the server and then click Apply.
Note: The timing server needs to be the last step in the setup. Mosaic, Scalable, etc. need to be configured and engaged before setting up the Nvidia sync.
