Quantum Ultra Videowall Processing System • Introduction 7
The following table gives a breakdown of common resolutions and the number of sources
at that native resolution that can be passed down a 400 Gbps HyperLane bus:
Width Height Frame Rate Bandwidth (Gbps) Number of Native Sources
1024 768 60 1.42 254
1280 720 60 1.66 217
1920 1080 60 3.73 96
1920 1200 60 4.15 86
1600 1200 60 3.46 104
2560 1600 60 7.37 48
3840 2160 30 7.46 48
4096 2160 30 7.96 45
3840 2160 60 14.93 24
4096 2160 60 15.93 22
4096 2400 60 17.69 20
NOTE: Bandwidth values do not include overhead data required for bus management.
Raw video throughput is slightly lower.
Virtual Network Computing (VNC)
The Quantum Ultra can decode multiple VNC streams from servers loaded on remote
desktops. The VNC streams can originate on the same network used for control or
on a separate network and accessed using the second LAN port available on the
Quantum Ultra.
Desktop resolutions up to 3840x2160 are supported, but the refresh speed of the desktop
content depends on the amount of content moving or changing on the remote desktop.
The size of the VNC window on the Quantum Ultra output and the number of VNC
sources simultaneously displayed also influence the refresh rate of the content.
The following table shows expected frame rates of a 1920x1080 desktop at various sizes,
quantity, and amount of content in motion:
