The Matrox M9138-E1024LAF is a graphics card in Low-Profile format with PCI Express x16 interface, designed for use in systems with limited space. It enables the simultaneous control of up to three DisplayPort monitors and supports a maximum resolution of 2560 x 1600 pixels per output. The card is intended for professional applications in office, administration, and industrial environments where stable and reliable multi-monitor support is required.

Applications
The graphics card is particularly suitable for workstations where multiple screens are used simultaneously, for example in control rooms, call centers, or technical development work. Support for independent screens or an extended desktop allows for flexible arrangement of the workspace. The card is also suitable for use in Windows Server environments as well as under Linux, with specific driver requirements available on the manufacturer’s website.

Functions and Features in Detail
The M9138-E1024LAF features 1 GB dedicated graphics adapter memory of type GDDR2 with a 128-bit memory interface, providing sufficient performance for graphics-intensive applications in office and industrial environments. The card supports OpenGL 2.0, which is relevant for rendering 2D and 3D graphics in professional software solutions. DirectX is not supported, indicating the target audience of the card — primarily users who do not run gaming or highly complex 3D rendering applications.

Technology Explained Simply
The graphics card operates with passive cooling, meaning no fans are used for cooling. This results in silent operation and increased reliability, as there are no moving parts. The Half-Height/Half-Length (HH/HL) form factor allows installation in compact computer enclosures, particularly in Low-Profile systems. The card is equipped with three Mini DisplayPort connectors, which can be converted to standard DisplayPort signals using the included adapters.

Compatibility and Accessories
The card is compatible with Microsoft Windows 7 (32/64bit), Windows XP (32/64bit), Windows Vista (32/64bit), Windows Server 2003/2008 (32/64bit), and Linux. For use under Windows Vista, support for the WDDM mode (Windows Display Driver Model) is provided, enabling optimal integration with the Windows Aero interface. Additionally, the card can be combined with a second M9138 graphics card to support up to six monitors. As an accessory, a DisplayPort to DVI adapter is available, enabling connection to DVI-compatible monitors.

Installation and Mounting
Installation is performed via the PCI Express x16 interface. The card is designed in Low-Profile format and is supplied with a retention bracket for full ATX format, allowing secure mounting in standard PC enclosures. The passive cooling requires no additional fans or special cooling measures, simplifying the installation process.

Operational Advantages
The card offers low power consumption and silent operation due to its fanless design. Desktop management features such as extending the Windows taskbar across multiple screens or configuring independent or extended desktops increase work productivity. The Matrox PowerDesk software enables easy configuration and management of screen arrangements. The card is ROHS- and WEEE-compliant and meets EMC Class B certifications, ensuring compliance with electromagnetic compatibility standards for use in office environments.
