DL380 Gen10 displays is blank on a APC 19" RACK LCD Console

[Chris Isaksen]

Our new DL380 Gen10 shows a blank screen on a APC 19" RACK LCD Console monitor (AP5719).   Keyboard works just fine but no screen display.  Firmware is all up to date.  KVM-USB has been swapped out along with the lan cable - no good.  The AP5719 works fine with Gen9 on down, even thought we need to set the "embedded video connection" to "Always enable". This is our standard on all servers and still no display.  Can only get a screen when connected to the the front display port on another monitor.  

This is just a VGA port what could HPE have changed to mess this up ?  Why can't they just use a basic/standard graphics gpu.

While iLO5 does have a newer Matrox chipset, it is still just standard VGA. You say it displays on another monitor connected to the front VGA port, will it also display on this monitor if it is plugged into the rear port?  Will the APC monitor work when connected to the front port?
