    		    Ascentia J and Win 95 Monitor Refresh Rate

    PROBLEM

    The Ascentia J system may not display the image properly on an external CRT,
    if the VGA was configured to any resolution with "High Color (64K)" depth,
    in a Windows 95 environment.

    CAUSE

    The refresh rate for 800x600x64K SimulScan mode is 56Hz.  The monitor used
    may not support this mode.

    SOLUTION

    Please review the monitor's specification for refresh rate.
