Description of this release
===========================
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.
New features
============
This software includes new features, especially for Matrox
hardware with DualHead support. These include:
- The use of different DualHead features (Multi-Display, DVDMax,
Zoom, and Clone) *without* restarting Windows
- Easier-to-use interface for DualHead controls
- Controls for dividing graphics resources (memory and bandwidth)
between your main and secondary displays
- More features accessible through user-defined hot keys (keyboard
shortcuts)
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
================================
- 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 (3D) support
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.)
- Video playback with DualHead modes
If you have a a DualHead supporting graphics card and you're
using DualHead Multi-Display, Clone, or Zoom mode, digital video
may appear as a solid color on your secondary display. This can
happen if video is played using the hardware-overlay feature of
your Matrox graphics card. Video played using the overlay
feature is generally of higher quality but it can be viewed only
on your main display.
Because only one program at a time can use the overlay feature,
any other program started while the overlay feature is used
won't be able to use the feature. The overlay feature will be
available to the first program to start after the program
currently using the overlay is closed.
For video that normally uses the hardware-overlay feature, you
may be able to view the digital video on your secondary display
by running another instance of the video player or by using a
video player that dynamically supports both hardware-overlay and
non hardware-overlay video playback (such as Microsoft Media
Player 7).
- 15-bit color palette support for Windows 2000/XP
For advanced users: By default, the 15-bit color palette is
unavailable for Windows 2000/XP. If you need to use this color
palette, you can make it available by adding the
"User.Enable15Bpp" value to your Windows registry and then
setting this value to "1". If you're adding this value, add it
under "HKEY_LOCAL_MACHINE" > "SYSTEM" > "CurrentControlSet" >
"Services" > "mgau" or "g200" or "g400" > "Device0". The value
type is "REG_DWORD".
- MPEG video playback and bus mastering
Mystique, Millennium II, Productiva G100, and G100 MMS -- While
playing MPEG video files with the bus mastering feature enabled,
your computer may stop responding. To disable bus mastering,
right-click your Windows desktop background, select "Properties"
> "Settings" > "Advanced" > "Options", disable "Use bus
mastering", then click "OK" > "OK" > "OK" to restart your
computer and for the changes to take effect.
