KVM displays blank screen when connected to HP ProLiant server
Question
KVMXXX displays blank screen when connected to HP ProLiant server
Issue
KVMXXX units display a blank screen when connected to the rear VGA port of an HP ProLiant server. In many cases, the KVM will fully function when connected to the front VGA port, if available.
Product Line
KVMXXX model KVM's - KVM0108A, KVM0116A, KVM0216A, KVM1116P, KVM2116P, KVM2132P
Environment
All serial numbers
All firmware versions as noted
Cause
The issue is linked to an older version of server BIOS having a conflict with the Extended Display Identification Data (EDID) supplied by the KVM.
Resolution
Disabling one of the VGA ports, or upgrading server BIOS to the most recent revision can resolve the issue. The next steps would be to set the BIOS setting for "embedded video connection" to "Always enable". Schneider Electric will not be able to assist with updating server BIOS - it is recommended before installing anything to a server that you speak with the server manufacturer first.
