Overview

This document addresses questions and problems with the use and
installation of Windows 95 and Matrox's MGA Millennium graphics accelerator
boards. Other MGA products are covered in the "Installing and Using Windows
95 with Matrox MGA Ultima, Ultima+, Impression, Impression+ and Impression
Lite Products " document. Windows 95-specific drivers for running Matrox
MGA products are included with Windows 95. These are version 1.00 drivers.
Matrox also supplies a version 2.00 driver which supports Powerdesk
features similar to our Windows 3.1 Powerdesk drivers for MGA. Version 2.00
drivers will be supplied with MGA Millennium boards manufactured after
August 24, 1995. These drivers may also be downloaded from our BBS (514-685-
6008) or CompuServe (GO MATROX). Note that the MGA Windows 3.1 Powerdesk
drivers and utilities cannot be used to run Windows 95.

Which Driver Should You Use

In general, you should use the Version 2.0 driver from Matrox. However, if
you did not receive it with your Millennium board and you cannot obtain
this driver easily, you can still use the Version 1.0 driver which is
supplied with Windows 95 CD. Please note that this driver is not supplied
with the floppy disk version of Windows 95. The primary additions to the
Version 2.0 driver are:

. MGA Property sheet (Windows 95 - compatible!)
. MGA Quick Access (practical floating tool
bar!)
. MGA Monitor Program (more control!)
. DDC-2b and Windows 95 monitor support (Plug and Play!)
. Improved performance (fast!)

The MGA Settings sheet in the Display Properties dialog box, which
complements the Windows 95 Settings sheet and provides access to the
Powerdesk features:

. A Desktop area that supports display resolutions up to 1600 x 1200,
to expand the working area beyond the limits of the monitor.
. PixelTOUCH, for hardware pan and zoom (x2 to x4).
. PanLOCK, to lock the working area of the virtual desktop.
. CenterWINDOW and CenterPOPUP, to center application windows and
popup windows in the currently-visible area on the monitor.
. An almost unlimited number of Display Schemes, to easily switch
between your preferred configurations.

In addition, the following programs are included with the Powerdesk
software:

The MGA Quick Access program, which is a re-positionable iconic menu which
complements the hotkeys to allow quick access to various Powerdesk
functions, including four preset modes.

The MGA Monitor program, which is an advanced program which can be used in
place of the standard Windows 95 Monitor selection process, for users who
wish to benefit from optimum refresh rates of their monitor and graphics
accelerator through interactive testing and adjustment.

Installation Tips for Version 1.0 Driver

1) The Version 1.0 driver is included with the Windows 95 CD in the
\DRIVERS\DISPLAY\ MATROX directory. If you are installing Windows 95 on a
system with a Millennium product already installed and want to use the
Version 1.0 driver, follow these steps:
. Start the Windows 95 Setup program. As part of the installation, a
hardware detection process will detect an "Oak Technology SuperVGA"
board. There is no cause for alarm - your computer will reboot in
standard VGA mode (640 x 480 with 16 colors), which is, of course,
supported by the Millennium.
. Once the Windows 95 installation is complete, install the
Millennium Version 1.0 driver. For more information on changing the
display driver, select Help from the Windows 95 Start button and
select "Display, driver, adding or changing" from the index.
Remember that you must select the driver from the
\DRIVERS\DISPLAY\MATROX directory. DO NOT attempt to install the
driver for the Matrox boards that appear in the Select Device list
since they only work with MGA Ultima\Ultima+\Impression+ models.
4) If you are adding the MGA to a system with Windows 95 already installed,
when you restart the system the hardware detection capabilities of Win95
should detect a new product installed. The hardware detection will detect
an Oak Technology Super VGA as above. Follow the steps in paragraph 1) to
correctly install the Version 1.0 drivers.
5) When you install the Version 1.0 drivers for your MGA card, it will only
support a 60 Hz refresh rate regardless of the Windows 95 monitor type
selected (selected from the Settings sheet in the Display Properties).
You can obtain higher refresh rates by using an MGA .INF file. This is
created by our Windows 3.1 Powerdesk drivers or by our DOS Setup program
and is normally found in the \MGA\SETUP directory. To use this file, the
following variable must be set in your AUTOEXEC.BAT file: SET
MGA=C:\MGA\SETUP. As well, create a [MGA.DRV] section in your SYSTEM.INI
file and add the line MGA_INF = 1 to it. DDC type monitors do not
automatically work under Windows 95 with the Version 1.0 driver. They
must be configured as any other monitor.

Known Problems or Limitations of the Version 1.0 Driver

There are no known problems or limitations with these drivers.

Installation Tips for Version 2.0 Driver

The 2.0 driver is supplied by Matrox with Millennium boards manufactured
after August 24, 1995. Owners of Millennium boards manufactured prior to
this can obtain the Version 2.0 drivers from Matrox's BBS or from
CompuServe. Complete installation information is provided with the drivers
in electronic format.

Known Problems or Limitations of the Version 2.0 Driver


|The version 2.0 drivers are tested extensively by Matrox and we have | |
|tried to eliminate as many problems as possible. The following is a list | |
|of problems which could not be fixed in time for the Version 2.0 release.| |
|They will be fixed in the next release of drivers. | |
| | |
| | |
|Windows 95 |Installing two Millennium boards causes a conflict |
| |preventing the system from booting. |
|America Online |After logging in, the application causes a GPF. Disable |
|(Windows) |the Matrox Control Center to avoid this problem. |
|Adobe ATM |Disabling the graphics acceleration causes Windows 95 to |
|(Windows) |lock up during its restart. This is an Adobe Type Manager|
| |(ATM) problem. ATM is installed by the Adobe Acrobat |
| |reader supplied with the Millennium online manual on the |
| |Superpack CD. ATM must be disabled to allow disabling of |
| |the graphics acceleration. |
|A number of problems are related to the "dragging" feature of the Plus | |
|pack. Disabling the dragging feature in the Plus properties in the | |
|Display properties eliminates these problems. | |
|Access 2.0 |Resizing a window over the Access window when the "show|
| |window contents while dragging" option of the pluspack |
| |is on will leave bits of the window behind. |
|AmiPro 3.01 |Moving a window over a crosshatch pattern in an Amipro |
|(Windows) |file while the view is enlarged corrupts the pattern |
|Hover 1.0 |When you pause while playing in full screen it only |
| |shows part of the screen. |
|Soundscape |Dragging the volume control slider will leave stray |
|utilities |pixels in the "rail" of the slider. |
|Lotus 123r4 |Parts of the status bar are not redrawn properly. |
|(Windows) | |
|QuickAccess |QA leaves its own image in some places on the desktop |
| |when you perform some operations |


Problems with Applications and Windows 95

If you discover a problem running an application that you think is related
to the video card such as screen corruption, there is a simple test you can
do before contacting Matrox support. You can disable the MGA's acceleration
features to see if this is the cause of the problem. To do this, start the
System properties from the Control Panel and select the Performance sheet.
Click the "Graphics" button and slide the hardware acceleration button to
None. Close everything and restart the system. If the problem still
persists, then the problem comes from the application or from Windows 95.
Contact the application vendor or Microsoft. If the problem disappears,
then the problem is may be with the MGA video driver. To confirm this, try
changing to the VGA drivers (640x480x16 colors) and see if the problem
persists. If the problem disappears, you should report the problem to our
technical support department. If possible, send a fax to 514-685-2853 or
email to graph_ts@matrox.com.
