HP Scalable Visualization Array Version 1.1 System Administration Guide

Surface, you must provide the correct host name of the display node connected to the display device
that is associated with each display block that makes up that Display Surface.
• Use both outputs from a graphics card to drive two display devices.
In this situation, graphics cards and display devices exist in a 1:2 relationship. The display node's
graphics card and the two display devices are physically connected by cables. If you have two graphics
cards installed in the display node, you can use one or both ports on the cards. The display devices
driven by the single display node represent a single display block. When you create a Display Surface,
you must provide the correct host name of the display node connected to the display devices that make
up the Display Surface.
Table 1-8 lists some of the display blocks in a sample cluster. The list is not exhaustive. For example, node
vis3 can be configured to have a 1 W x 2 H layout.
