Release description
-------------------
This is the Matrox Windows NT Display Driver. It supports Microsoft
Windows NT for x86 CPU's, version 4.0 (Build 1381).
This product includes:
- Display Driver
- Matrox PowerDesk for Windows NT 4.0
The driver can support up to 5 Matrox cards (of the same model) in a
computer at the same time.
Notes, Problems, and Limitations
--------------------------------
Computers with more than one PCI bus
It is possible that a switch to a full-screen Command Prompt, or any
change of mode, will result in a blue-screen crash if a card is
installed on a PCI bus other than bus 0. The problem is under
investigation. Moving the card to a different PCI slot is a possible
workaround.
There are systems where Windows NT reports conflicts between adapters
installed beyond the PCI bridge. In this case, the Matrox
miniport driver cannot access its own card. If your system appears
unable to find the card, try moving it to a different PCI slot.
Installing Microsoft Service Pack 3 for Windows NT 4.0 should fix
many of these problems.
DirectDraw with virtual desktops
Some DirectDraw programs don't work properly with virtual desktops.
We recommend you run DirectDraw programs with a normal desktop.
3D-Maze screen saver
Display problems may appear while using the "3D-Maze" screen saver.
These may happen after Microsoft Service Pack 2 for Windows NT 4.0 is
installed. These display problems are apparently fixed by Service
Pack 3.
GLDemo textures
If you have a Matrox Millennium II graphics card, textured objects
in GLDemo may be Gouraud-shaded instead of textured in 3D-accelerated
display modes. This problem is apparently fixed by installing
Microsoft Service Pack 3 for Windows NT 4.0.
Zoom feature with Matrox Millennium
If you have a Matrox Millennium (*not* Millennium II) graphics card
and you use the Matrox zoom feature, a vertical band may appear at
the right edge of your desktop (beyond the 1152 pixel limit) because
of a hardware limitation. This only happens if your display is
using a 1152 x 864 resolution and a 256-color palette.
Running Winstone 97
The CenterPOPUP feature should be disabled (which is the default
setting) when running the Winstone 97 benchmark. Some tests may
report a time-out error if CenterPOPUP is used.
Limitation with multiple graphics cards
Windows NT 4.0 supports a maximum of about 280 different display
modes (combinations of resolution, color palette and refresh rate
settings). You may encounter this limit if you have more than one
Matrox graphics card installed in your computer.
If the Matrox "VESA settings" option button is selected when there
are multiple Matrox cards in your computer, you're even more
likely to encounter the Windows NT 4.0 limit in the number of
display modes. This is because the "VESA settings" option supports
several different refresh rates for each display resolution and
color palette setting.
Because of the limitation in the number of display modes, the 15-bit
color palette setting is not available when multiple graphics cards
are installed and the "VESA settings" option is selected.
If you have more than one Matrox graphics card in your computer, we
recommend you not use the "VESA settings" option. Note that changing
your refresh rate through the Microsoft "Display Properties" dialog
box activates the "VESA settings" option.
Display settings for Plug-and-Play monitors
For each resolution, Plug-and-Play (DDC) monitors report to your
computer the refresh rates they're capable of. At high resolution
and color palette settings, your Matrox graphics card may not support
the high refresh rates supported by some monitors.
For example, at a 1600 x 1200 resolution with a 24- or 32-bit color
palette setting, your monitor may report that it's capable of
an 85 Hz refresh rate. However, at this display setting, your
graphics card may only be capable of a 75 Hz refresh rate.
When the refresh rate reported by your monitor can't be supported,
the Matrox display driver uses the next highest VESA refresh rate
supported by your graphics card. This is indicated by the text
"(VESA)" in the "Refresh frequency" box in the "Matrox Display
Properties" dialog box.
If the Matrox display driver uses a refresh rate different from the
capability reported by your Plug-and-Play monitor, the screen image
on your monitor may need to be resized or repositioned.
3D Studio MAX 1.2
If you have problems running 3D Studio Max 1.2 using the Matrox
HEIDI driver, try disabling the "Use bus mastering (OpenGL)" check
box under "3D settings". To access this check box, click "Start" ->
"Programs"-> "Matrox PowerDesk" -> "Matrox Display Properties" ->
"Performance".
3D Studio MAX 2.0
Switching between HEIDI software emulation and OpenGL acceleration
while 3D Studio Max 2.0 is running, may cause the viewports to
flicker while playing animations. This problem may also happen if
display settings (resolution or color palette) are changed while
3D Studio Max is running. If you experience these problems, try
closing 3D Studio Max, changing your display settings (resolution or
color palette), and then restarting 3D Studio MAX.
TV output mode
Certain models of Matrox graphics cards support TV output. When TV
output mode is enabled with Matrox PowerDesk software, some computer
monitors may become garbled or unusable. This may happen with a
computer monitor that only supports a maximum resolution of
1024 x 768 or lower.
If this happens, simply turn off your computer monitor and use your
TV to view your computer display. Your computer monitor will work
normally when you disable TV output mode.
Note: The Matrox zoom and virtual desktop features aren't supported
in TV output mode
Download Driver Pack
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.
