Attention Before you change any monitor settings, be sure to review the information that comes with your monitor. Using a resolution or refresh rate that is not supported by your monitor might cause the screen to become unreadable and damage the monitor. The information that comes with your monitor usually includes the resolutions and refresh rates that the monitor supports. If you need additional information, contact the manufacturer of the monitor. To minimize screen flicker and jitter, set your monitor for the highest noninterlaced refresh rate that the monitor supports. If your monitor complies with the VESA 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 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-ConfigureUtility Program CD for your computer. Instructions for installing the device drivers are provided on the Ready-to-Configure Utility Program CD in the README file that corresponds to your operating system. IBM also maintains the latest versions of video device drivers for all IBM-manufactured computers on the World Wide Web. 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 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 video controller in your computer supports the use of AGP, 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. Chapter 3.
