The public network (172.19.*) provides 10 Gbit/s connectivity between machines
and internet access. It is used for communication to and from the nodes, including
VNC, RDC, WSUS and domain services.
The private network (192.168.29.*) also provides 10 Gbit/s connectivity between
machines. NDI is configured on this network, which supports multicast. It is used
for communication between nodes by applications such as OpenSpace and C-play.
General settings
Always set the display to 100% in scaling.
For ATLAS-01 to ATLAS-04 move taskbar to the TOP.
For all nodes, make sure it hides/shows on hover.
Synchronization
Synchronization master is ATLAS-01. All nodes run a sync fix script at startup, so nodes can be restarted in any order — wait until the command line popup and blinking on all machines have finished before continuing.

NVIDIA settings
Active stereo (emulated through dual DP-ports, i.e. passive stereo)
To enable active/passive stereo you need to set "Stereo –Enable" to "On". Swap eyes should not be needed if you use the GPU connection setup as specified in "SBS setup" below. "Stereo – Display mode" needs to be "Clone mode".
Activation and disable of active stereo can be done through two scripts (set_passive_stereo_XDL4K_59_94.bat) and (disable_mosaic.bat). Always remember to change to the correct resolution (4096x2160) for both displays, before trying to set passive stereo.
SBS (Side-by-side) setup
It is important to set "Stereo –Enable" to "Off" when utilizing SBS stereo.
GPU connection cords: Always connect the LEFT display to the top DP port in each computer (as it is mounted in the rack). Then connect the RIGHT display beneath it. Always remember to change to the correct resolution (4096x2160) for both displays, before starting Mosaic configuration. Then you can setup SBS as this in the Mosaic configuration:
Note:
Atlas-00 has a GPU that might be somewhat faulty. Should not be moved to a node.
