Matrox PowerDesk software includes a display driver and display utilities.
With this software, you can take full advantage of your Matrox graphics 
hardware and you can access additional Matrox display-related features.


Installation
============

To install Matrox PowerDesk, start the "setup" program included with it, 
then follow the on-screen instructions.

The setup program will only install software if a Matrox graphics card model
supported by the setup program is installed in your computer. 


More information
================

For more information on Matrox PowerDesk, see the help file included with it. 
For information specific to your Matrox graphics card, see your Matrox or 
system manual.


Notes, problems, and limitations
================================

- DirectDraw, Direct3D and DirectVideo support

  The DirectDraw driver we provide is compatible with DirectX 2 (and
  later) and includes Direct3D support. For our DirectDraw/Direct3D
  driver to be called, and benefit from hardware acceleration,
  Microsoft DirectX 2 (or later) MUST be installed, even for programs
  originally made for DirectX 1.

  Also, if a recent version of DirectX isn't installed, some Matrox 
  PowerDesk features may not be available.

  We provide DirectX on the Matrox CD-ROM. The latest DirectX is
  available from the Microsoft Web site, and is included with many 
  DirectX programs.

  IMPORTANT: If the DirectX setup program prompts you to replace the
  existing display drivers, click "No". Otherwise, the setup program 
  installs display drivers which are not as optimized as the Matrox 
  drivers and which do not support PowerDesk software.

  Note that depending on the origin of your Microsoft DirectX software, 
  it may not include DirectVideo support. For faster playback of Indeo 
  and Cinepak AVI files, you should install Microsoft DirectVideo 
  support. 

- Matrox bus mastering

  This driver supports bus mastering. Bus mastering is a feature that 
  allows expansion cards to perform tasks at the same time as your 
  computer's CPU. If you have a fast Pentium computer (faster than 
  166 MHz), the display performance of most programs is improved when 
  bus mastering is used.

  To use bus mastering with 3D (DirectX) programs, your graphics card 
  needs an interrupt request (IRQ). Most computers automatically assign 
  an IRQ to graphics cards, but some do not. If your graphics card hasn't 
  been assigned an IRQ, programs that use Matrox bus mastering may not 
  work properly. For more information, see your Matrox or system manual.

- Monitors in interlaced mode

  Some older monitors such as the NEC 3D and many "Super VGA" monitors
  do not support non-interlaced mode in all resolutions. The Matrox display 
  driver does not properly handle interlaced mode with the Windows 
  monitor selection method. If you have one of these monitors, please 
  use the Matrox Monitor selection method.

- DirectDraw and Automatic Power Management

  As stated in "Microsoft DirectX Release Notes", September 30, 1995, a 
  DirectDraw game may be unable to restore properly if it is suspended 
  by Automatic Power Management utilities.

- Installation in different language versions of Windows

  If you install software in a language different from the language of 
  your operating system (for example, English software on a Japanese 
  system), you may have problems with text and dialog box controls being 
  cut off. This is because of differences in system fonts.

- OpenGL support

  Note the following limitations related to the OpenGL driver included with
  Matrox PowerDesk:

    - OpenGL support may not be included in some versions of Matrox PowerDesk.
      For a version of Matrox PowerDesk with OpenGL support enabled, see
      the Matrox Web site (www.matrox.com/mga).

    - Regardless of your graphics card or display driver, Windows 98 only 
      supports OpenGL acceleration with the primary display of your computer.
      (The "primary display" is the one that first displays information when
      you restart your computer.)

    - With the "Tribes" game, you may notice some minor display artifacts and 
      the opening video introduction may not display properly.

    - Using 3D Studio Max 2.0, you may experience problems with the viewports
      being improperly redrawn. If this happens, simply click in a viewport 
      to properly update their display. (This problem isn't present with 
      version 2.5 or 3.0 of 3D Studio Max.)

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
