to get the best possible image on your screen and to reduce flicker, you might need to reset the resolution and refresh rate of your monitor. you can view and change monitor settings through your operating system using the instructions in the readme files on the device drivers and ibm enhanced diagnostics cd or in the c:\ibmtools\drivers\ directory on the hard disk of your computer. see your operating-system documentation for more information about monitor settings.

    before changing monitor settings, review the documentation 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 could damage the monitor. the information that comes with your monitor usually includes resolution and screen refresh rates that your monitor supports. if you need additional information, contact the manufacturer of the monitor.

    if you are using a cathode ray tube (crt) monitor, set your monitor for the highest noninterlaced refresh rate that the monitor supports. if your monitor complies with the video electronics standards association (vesa) display data channel (ddc) standard, it is probably already set to the highest refresh rate the monitor and video controller can support. if you are not sure whether your monitor is ddc-compliant, see the documentation provided with the monitor.

    if you are using a flat-panel monitor, the refresh rate does not have to be set to the highest noninterlaced refresh rate that the monitor supports. flat-panel monitors produce flicker-free images even when they are operating at a minimum 60 hz noninterlaced rate.

    if you have a dual-monitor video adapter, see the video adapter device driver readme file and documentation for more information about enabling dual-monitors.
