The "Powerwall", manufactured by 9X Media, is composed of nine LCD screens placed in a 3x3 grid. Each monitor has a 1280x1024 (SXGA) resolution, and is driven by a node of the Boba cluster, which is operated and supported by SInRG.
See this page for access information.
The following diagram shows which machine is connected to which monitor.
boba142 is used as the head node, which must be used to call applications which use the powerwall as a whole, such as Chromium.
