G40 display not seen as DDC1 on IBM PC 340 system
Applicable to: World-Wide
Symptom :
IBM PC 340 Series 6560 systems may fail to recognize the IBM G40 Color Display as a DDC1 compliant monitor in the Setup Utility and may cause display failures during operation.
Problem Isolation Aids :
During the setup of the IBM G40 display in the 6560 system Setup Utility, the option for DDC1 capability may not be shown as an available setting. This setting is only available if the system detects that the monitor attached is DDC1 or DDC2B compliant. The IBM G40 display is DDC1 compliant.
This problem may also produce a failure of not displaying the IBM logo and POST test during startup. The operating system startup will be the first images displayed.
No other IBM or OEM DDC1/DDC2B compliant display has exhibited this problem.
Fix :
Use either of the following procedures to setup the IBM G40 display on a PC 340 6560 system:
Systems using DOS/Windows 3.11 or OS/2 WARP
1- Press F1 during POST to access the Setup Utility.
2- Select Devices and I/O ports.
3- Select Video
4- Disable DDC
5- Select Custom Monitor type
6- Fill in the refresh rates for the IBM G40 display.
640x480 - 75 hz
800x600 - 60 hz
1024x768 - 43 interlaced
7- Press ESC twice.
8- Select Save and Exit
Systems using Windows 95
1- Boot to the Windows95 Desktop.
2- Click right mouse button on the Desktop.
3- Select Properties.
4- Select Refresh Rates.
5- Fill in the refresh rates for the IBM G40 display.
640x480 - 75 hz
800x600 - 60 hz
1024x768 - 43 interlaced
6- Click OK.
Users with multiples of the SAME machine type may use the CMOSCOPY.EXE file to copy a systems CMOS configuration to another system. This eliminates the need to manually configure each system using the Setup Utility.
