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 provided in the readme files on the device driverand ibm enhanced diagnostics cd (in the video device driver) that comes with your computer. see your operating system documentation for more information on monitor settings.

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

    to minimize screen flicker and jitter, set your monitor for the highest non interlaced 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 the monitor and video controller can support. if you are not sure if your monitor is ddccompliant, see the documentation provided with the monitor.

    if you have a dual-monitor video adapter and you connect both monitors but the second monitor doesn't work, do the following:

    1.go to start→,settings→,control panel

    2.double-click display properties-,settings-*display type.

    3.enable the multi-head option.

    4.close all control panel windows.
