IBM PC Server/IBM PC - OEM monitor fails
Applicable to: World-Wide
Symptom:
Systems utilizing an S3-Vision 864 chip set, such as IBM PC 300/700 systems, may experience unexpected Video configuration errors when an OEM monitor is connected to the system unit. This problem applies to OEM monitors that implement the VESA Display Data Channel (DDC) standard.
This problem has been seen on "NEC" XE15, XE17, XE21, XP15, XP17, and XP21 monitors. It may also occur on other vendor monitors when connected to an IBM system, or with IBM DDC Compliant monitors attached to other vendor's system units.
85xx and 95xx Micro Channel systems using XGA-1, XGA-2, Image Adapter/A or Image-I Adapter/A could also experience video problems with OEM DDC monitors.
Problem Isolation Aids:
- The system displays a 162 error at POST. The set-up utility indicates a change has occurred in the video selection.
- The power LED on the monitor flashes, indicating that the display has lost sync or entered the power saver mode.
- The failure does not occur if the system is powered on 10-15 seconds prior to the monitor.
- An IBM monitor with DDC does not exhibit the above symptoms, whether it is DDC enabled or not.
- The IBM PC 300/700 system is NOT at Flash BIOS Level 65A or higher
Fix:
This is an OEM monitor incompatibility. No system parts should be replaced in an attempt to fix this problem.
- PC 300/700 BIOS level 65A and higher corrects this problem.

Note:
BIOS level 65A or higher has the support for DDC1. To enable this support, access the Setup Utility and select the Devices and I/O, then Video Setup. Enable DDC1 Checking. Enabling DDC1 checking will cause a 20 second delay during POST to allow the system and monitor to synchronize.
- As an immediate workaround the IBM PC 300/700 system should be powered on first, at least 10-15 seconds prior to turning on the monitor.
85xx and 95xx Micro Channel systems using XGA-1, XGA-2, Image
Adapter/A or Image-I Adapter/A must be powered on 10-15 seconds prior to turning on the monitor.
Notes:
DDC (Display Data Channel) allows basic configuration information to be passed between the system unit and the monitor. This enables the system unit to automatically configure for optimum monitor performance. This capability is sometimes referred to as "Plug'n Play"
