Matrox Display Wall – System Builder’s Guide 85
It has been assumed until now that systems used for Mura-based Display Walls are based on a switched architecture (that is, the PCI-Express
connectors are connected to PCI-Express switches that form the fabric, or backbone, of the system architecture) in order to provide multiple
PCIe slots for add-in cards. However, there are many system motherboards that provide a smaller number of slots that do not use a switch-
based architecture, but rather use lane-based architecture to provide multiple PCIe slots. In some cases, there are a fixed number of lanes
available from the host chipset that can be “allocated” among the various physical PCIe slots, depending on the presence of an adapter (for
example, a system may permit a specific slot to be configured in x16 mode if the adjacent slot is unoccupied, or in x8 mode if an adapter is
placed in the adjacent slot). In such cases, knowledge of the capabilities of the motherboard is essential to properly configure the system so as
to maximize the overall performance.
