- Release description
- ===================
-
- This is the Matrox Windows NT Display Driver. It supports
- Microsoft Windows NT for x86 CPU's, version 4.0 (Build 1381 -- or
- later).
-
- This product includes:
-
- - Display Driver
- - Matrox PowerDesk for Windows NT 4.0
-
-
- 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.
-
-
- Using Matrox PowerDesk
- ======================
-
- Changing resolution, selecting a monitor, and using the Matrox
- PowerDesk is covered in the "online.doc" file. You can view this
- file with WordPad.
-
-
- Hardware-accelerated 3D
- =======================
-
- For 3D hardware acceleration, the Matrox Windows NT 4.0 display
- driver supports the OpenGL interface with 2 driver types -- MCD
- (Mini Client Driver) and ICD (Installable Client Driver). The
- Matrox Millennium, Millennium II, Mystique, Mystique 220, and
- G100-based graphics cards have MCD support. The Matrox G200-based,
- G400-based and later graphics cards have ICD support. (An ICD has
- more potential for optimization than an MCD.)
-
- 3D hardware acceleration has the following restrictions:
-
- - Currently no acceleration is available when multiple cards are
- in use.
-
- - The MCD/ICD does not support 8 bpp (256 colors) and 24 bpp
- (16777216 colors) modes. 16 bpp (64 K colors) and 32 bpp (True
- Color) modes are the ones that can be hardware-accelerated.
-
- - Limitations to the available resolutions are to be expected. All
- 3D modes require extra memory to handle double buffering and/or
- Z-buffering, and this memory is no longer available for display.
-
-
- Notes, problems, and limitations
- ================================
-
- - Service Pack 4 or later recommended
-
- To avoid potential problems, we recommend you install Service
- Park 4 (or later) for Windows NT 4.0.
-
- - 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 can't 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 4 (or later) 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 4 (or later).
-
- - 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.
-
- 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.
-
- - 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" check box
- under "General settings". To access this check box, click
- "Start" > "Settings" > "Control Panel" > "Matrox Display
- Settings (double-click)" > "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.
-
- - 15-bit color palette support
-
- A 15-bit color palette is no longer supported.
-
- - OpenGL support
-
- Note the following limitations related to the OpenGL (3D) driver
- included with your Matrox display driver:
-
- - If you have a newer Matrox product or your Matrox software
- was provided by the manufacturer of your computer, full
- OpenGL support may be disabled with your Matrox display
- driver. For a Matrox display driver with full OpenGL support
- enabled, see the Matrox Web site (www.matrox.com/mga). (If
- your Matrox product was provided by the manufacturer of your
- computer, check the Web site of that manufacturer for a
- display driver. A display driver provided by the
- manufacturer of your computer is more likely to be tested
- with your computer model.)
-
- - In multi-display mode under Windows NT 4.0, OpenGL
- acceleration is only available if DualHead graphics hardware
- is the only graphics hardware you're using. (Multi-display
- OpenGL acceleration isn't supported with Matrox MMS products
- or with more than one graphics card in your computer.)
-
- - 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 later) of 3D
- Studio MAX.
-
- - System memory requirements
-
- Because of a limitation in Windows NT 4.0, you may experience
- problems if your computer doesn't have more system memory than
- the total amount of graphics memory used in your computer. To
- determine the amount of graphics memory used in your computer,
- add the total amount of graphics memory on each installed Matrox
- graphics product in your computer.
-
- Depending on your total amount of graphics memory, here are some
- recommended amounts of system memory for Windows NT 4.0:
-
- | Graphics memory | System memory |
- | (total) | (recommended) |
- +--------------------+--------------------+
- | 32 MB | 64 MB or more |
- | 64 MB | 128 MB or more |
- | 128 MB | 192 MB or more |
- | 160 MB | 256 MB or more |
-
- - Full-screen DOS support with multiple graphics chip
-
- If you have more than 10 graphics chips in your system (for
- example, 3 Matrox MMS-Quad cards), your system may stop
- responding when running a DOS program in full-screen mode. If
- your DOS program supports it, run it in a DOS window.
-
-
- Matrox TV output
- ================
-
- Certain models of Matrox graphics cards support TV output. With TV
- output support, you can view or record your computer display with
- a TV or video recorder connected to your graphics card.
-
- Recommendation
- --------------
- - While playing games using TV output, we recommend you use a 640
- x 480 display resolution. This is because the resolution
- capabilities of TVs are lower than most computer monitors. If
- you use a higher display resolution (800 x 600 or 1024 x 768),
- the display on your TV may not look as sharp as the display of
- your computer monitor -- that is, some of the extra detail may
- be harder to see on your TV.
-
- - For Matrox G100/G200 graphics cards with TV output support:
- Matrox default advanced TV output settings are good for viewing
- most computer graphics (for example, computer games or your
- Windows desktop) on most TVs. Based on broadcast standards,
- there are advanced TV output settings that are better suited for
- viewing full-screen video (for example, from a video file).
- These settings are:
-
- NTSC
- - Brightness: 180
- - Contrast: 234
- - Saturation: 137
- - Hue: 0
-
- PAL
- - Brightness: 167
- - Contrast: 255
- - Saturation: 138
- - Hue: 0
-
- Note: For ideal settings, you may also need to adjust the
- settings on your TV. The default brightness, contrast,
- saturation and hue settings on most consumer video devices are
- higher than broadcast standards. These settings are usually okay
- for viewing video but may not look okay with computer graphics.
- (This is why Matrox default TV output settings are lower than
- what's ideal for video.) For more information on how to adjust
- settings on your TV, see your TV manual.
-
- More information
- ----------------
- For more information on display settings, see your Matrox manual
- and online documentation. For information on how to change the
- display resolution of a game you're using, see its documentation.
-
- Note: The Matrox zoom and virtual desktop features aren't
- supported in TV output mode. Also, TV output mode isn't supported
- if you have more than one Matrox graphics card in your computer.
-
- Note: For TV output with full-screen DOS display modes under
- Windows NT 4.0, only text display modes (02h, 03h) are supported.
