    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.
