The information in this article applies to:
  • Microsoft Windows NT Workstation version 3.51
  • Microsoft Windows NT Server version 3.51

SYMPTOMS

After you apply Service Pack 4 (SP4) to an IBM ThinkPad 755CE/CSE/CD/CX/CV/CDV, 750C/755C, 370C, or 345C, you cannot go to higher resolutions than VGA with 16 colors.

RESOLUTION

After applying SP4, reinstall the IBM driver downloaded from IBM again. The driver can be downloaded from IBM (www.ibm.com). It is a self extracting file named Vf75xwnt.exe.

The old version of the driver downloaded from IBM (dated 10/7/95) needs to be set up again after SP4 is applied.

MORE INFORMATION

IBM ThinkPad 755CE/CSE/CD/CX/CV/CDV, 750C/755C, 370C, and 345C use the Western Digital video chip set. For resolutions higher than 640x480x16, the driver from IBM is needed. The driver name is Wdvga.sys. If SP4 is applied to one of these systems that have the SVGA driver loaded, it replaces the Wdvga.sys, which brings back the system to standard VGA 16 colors.
