[English] PDREADME.TXT MATROX GRAPHICS INC. 2002.02.20 Matrox PowerDesk for Windows 2000/XP Revision 5.82.018 Contents ======== - Description of this release - Installation - [English...]New features[...English] - More information - Notes, problems, and limitations 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.
