Display Data Channel (DDC) standard, it is probably already set to the highest refresh rate that the monitor and video controller can support. If you are not sure if your monitor is DDC-compliant, refer to the documentation provided with the monitor. Video Device Drivers To take full advantage of the Matrox MGA-1164SG 3-D video controller in your computer, some operating systems and application programs require custom software, known as video device drivers. These device drivers provide support for greater speed, higher resolution, more available colors, and flicker-free images. The video device drivers are provided on the Ready-to-Configure CD that comes with your computer. Instructions for installing the device drivers are provided on the Ready-to-Configure CD in the Matrox README file that corresponds to your operating system. (When you open the README file, a prompt might appear requesting you to specify Mystique or Millennium. Specify Mystique.) If your computer has IBM-preinstalled software, video device drivers have already been installed on the hard disk in your PC. However, the device driver installation instructions in the Matrox README file will be helpful if you ever need to reinstall the device drivers; if you want to change video resolution, color depth, or monitor settings; or if you need information on obtaining and installing updated device drivers. Video Controller The Matrox MGA-1164SG 3-D video controller in your computer supports the use of a bus master, which can speed up the process of displaying video graphics. This feature for the video controller is activated by the video device drivers when the video interrupt feature is set to Enabled (the default) in the Configuration/Setup Utility program. If you leave the bus master activated, the video device drivers and the video controller operate at a faster speed. When the video controller needs information from system memory, the video controller can become the bus master and fetch the information directly from memory. This means the video controller will not have to wait for the microprocessor to read the information and write it to video memory. You can deactivate the bus master by changing the video interrupt setting from Enabled to Disabled, using the Configuration/Setup Utility program (described on page 37). 24 Using Your Personal Computer
