Notes, Problems, and Limitations
--------------------------------
- Another MGA driver on the Windows 95 CD-ROM
This driver is part of the Windows Driver Library (WDL). In the
Adapter Type field (Display Properties dialog box Settings tab ->
Change Display Type button), this driver is called Matrox MGA
Millennium, while the PowerDesk one is called Matrox MGA PowerDesk.
The WDL driver does not support PowerDesk.
- Windows 95 "display.txt" file
Windows 95 comes with a readme file called "display.txt" containing
valuable information related to display adapters.
Note that the remarks about the Matrox MGA adapters refer to the
Microsoft MGA Ultima/Impression driver, not to your MGA PowerDesk
driver.
- Adobe Type Manager limitation
When Adobe Type Manager is installed, you cannot run the driver if
the "Advanced Graphics Acceleration Settings" is set to none. Note
that ATM is installed as part of Adobe Acrobat Reader. This is an
Adobe problem documented in the Windows 95 "display.txt" file.
- Monitor configuration when upgrading from Windows 3.1
Take note that an old MGA.INF file created by the Windows 3.1 Monitor
Selection Program is still compatible with the Windows95 driver, but
will not contain any data for the 1152 X 864 resolution, forcing the
Windows 95 driver to fail in 640 X 480 for that resolution. We then
highly recommend that you reselect a monitor with the MGA Monitor
Selection property sheet as soon as you finish installation of this
software product.
- Monitors in interlaced mode
Some old monitors such as the IBM 8514 and the NEC 3D do not support
non-interlaced mode in all resolutions. The MGA driver does not
properly handle interlaced mode under the Windows 95 monitor
mechanism, so if you own one of these monitors, please use the MGA
Monitor Program.
- PowerDesk and localized versions of Windows 95
When PowerDesk installs its special settings page in the Windows 95
Display Properties panel, it should grey-out the normal Microsoft
"Settings" page. This has been tested under the languages we have
localized PowerDesk in. With other languages, it may not work. In
this case, DO NOT USE THE MICROSOFT SETTINGS PAGE. Otherwise, you
will confuse the MGA display driver, which uses the Windows 95
"Desktop area" as its VIRTUAL desktop area; rather than changing
your resolution, you will actually change your virtual desktop.
- DirectDraw and Automatic Power Management
As stated in "Microsoft DirectX release Notes" dated September 30,
1995, A DirectDraw game might be unable to restore properly if it
is suspended by Automatic Power Management utilities.
- Video acceleration under Windows 95
Microsoft DirectX is supported in this release of the MGA driver,
including DirectVideo, which provides faster Video for Windows
playback with programs such as Media Player.
For an application to use DirectX, a number of support files are
required. These files include DirectDraw system components,
DirectVideo system components, and updated Indeo and Cinepak codecs.
In order to facilitate installation and setup of DirectX, Matrox
has provided a DirectX upgrade package along with setup program on
our BBS, WEB page and newest MGA CD-ROM.
Even if you already have DirectVideo and DirectDraw installed on your
system, we recommend you run the setup program included in the
DirectX upgrade provided by Matrox in order to update the various
codecs. The MGA DirectDraw driver has been optimized for the best
possible video playback which requires the Indeo 3.2 codec version
3.24.15.03 and the Cinepak codec version 1.10.0.6 which are both
found on the above mentioned DirectX upgrade.
To start the installation of the DirectX upgrade, use the RUN function
from the START menu and type A:\SETUP.EXE (if you downloaded the
upgrade and put it on diskettes), or D:\MGASETUP.EXE (if you have it
on your CD-ROM).
Note: ONCE THE SETUP PROCEDURE IS COMPLETE, YOU MUST REBOOT YOUR
COMPUTER.
