TITLE:  Ascentia P     and Samtron Monitors
 
 
ISSUE 
 
   The Ascentia P system may display distorted video on a Samtron 
   monitor under the Windows 95 operating system.
        
   This issue affects the following systems: 501997, 503039, 503040, 
   and 503041.    

 
BACKGROUND 
 
   When an Ascentia P is set to simultaneous display with the LCD 
   panel closed, the screen becomes distorted under Windows 
   Explorer. In Windows Explorer, the vertical bar that divides the 
   folders and contents will become s-shaped, looking  rough and 
   jagged. This distortion is caused because the Windows 95 display 
   properties do not match the exact specifications of the external 
   monitor attached. 
       
   When the unit is set for simultaneous display with the LCD panel 
   open, the display functions properly.    

 
ACTION 
 
   To resolve the issue, perform the following steps:
   
   1. Download the Samsung  display drivers, file name
      SAMSUNG.EXE, from Microsoft’s Web page at:
     
    http://www.microsoft.com/kb/softlib/mslfiles/samsung.exe 
   
   2. Update the Windows 95 display list.
   
   3. Follow the install procedures as outlined in the 
      INSTALL.TXT file included with the SAMSUNG.EXE file.
        
   Make changes in the refresh rate depending on the resolution and 
   type of Samtron monitor being used. The following configurations  
   have been tested and are known to work:    

 
NOTES 
 
   This issue has only been seen at resolutions greater than 640x480 
   on TFT displays.
