Microserver Gen10 - No video output via DIsplay port when the VGA port is not connected

Hi,

I am having some issues getting video out of the DP (diplayport) and would appreciate any help. Most of the tests I did where with CentOS 7.

If I connect my server via DP  it has no video output. If I connect the the server to two screens (one via DP the other via VGA), both screens works fine, but only after the OS is loaded. At boot and in the BIOS menu only the VGA is working.
Once the OS is loaded and I have output in both screens, I can change primary, set up mirror,etc. But as soon as I remove the VGA connection, the DP stops sending video.

As per the above, the problem doesn't occur when the VGA port is connected to another screen at the same time.
I also tried to to change the graphics config in the BIOS, from automatic to forced, but same results.

 

Thank you
