  • 1 GB memory handles multi-display workloads
  • Pair two cards for up to eight monitors
  • Supports independent or stretched desktop modes

Multi-monitor workstation card

The Matrox M9148 LP PCIe x16 graphics card drives up to four DisplayPort monitors from a single low-profile board. It targets business, industrial and government users who need reliable multi-display output rather than 3D rendering power. The card fits compact chassis where full-height cards cannot be installed. Paired with a second M9148 it can drive eight monitors from one system.

DisplayPort limits and memory

Each of the four outputs supports resolutions up to 2560 x 1600, so the total pixel count across all heads stays within the 1 GB frame buffer. The card uses a PCIe x16 electrical interface, but bandwidth is governed by the host platform and the DisplayPort standard it implements. Independent or stretched desktop modes are handled by the driver without extra hardware.

Upgrade path and fit

This card replaces older dual-head or single-head Matrox boards when a workflow demands four simultaneous displays at 2560 x 1600. The jump is worth it when the application requires independent desktops across all outputs or a single stretched canvas. It is not for buyers who need 3D acceleration, higher per-output resolution, or more than 1 GB of video memory.

Questions about this item

Which memory capacity should I choose for the M9148 LP?

The M9148 LP is offered with 1GB of memory, a single capacity suited to driving four DisplayPort outputs at up to 2560 x 1600 each.

What does the 2560 x 1600 resolution mean when the card is installed?

Each of the four DisplayPort outputs can drive a monitor at 2560 x 1600 simultaneously, giving a large combined desktop across all screens.

What does the PCIe x16 interface provide for this card?

The PCIe x16 slot supplies the bandwidth needed for four independent DisplayPort outputs at 2560 x 1600 and allows a second M9148 to be added for eight monitors.
