		    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.
