M910s : Force VGA output at BIOS level when both DP and VGA are in use?

Hi,

 

I am looking for a BIOS settings on M910s to force VGA in Post instead of DP, can you point me in the right direction?

 

Cheers,

Nicolas

The DP and VGA are from the same video card, right? Is it an onboard video card?  Would you mind describing more about your scenario?

Hi TicTac1,

 

Thanks for your reply.

 

We are using the onboard video card (VGA + 2 x DP)

 

The scenario is as following, we have 36 x M910s separeted in 2 groups of 18 :

--> single view over VGA

--> dual view over VGA and DP

 

All the PCs are connected to a KVM extender then on the Transmitter there are a local console were a KVM over IP is connected for remote access.

 

The KVM over IP dongle is only analogue and are all connected to the VGA port of the PCs.

In single view scenario when the PC starts it can be controlled at BIOS level through the KVM over IP, however in the dual view scenario, I can't see the POST message or BIOS image via the KVM over IP (VGA) because the M910s output only the POST to the DP port. If I disconnect the DP connection it goes straight to the VGA.

 

I am looking for a way to force VGA output always during post and BIOS operation.

 

Let me know if you need more details.

 

Nicolas

I'm afraid the setting entry was not available for end user. According to hardware certification requirements, DP output is the first priority

I'm thinking that if a DP->VGA dongle could be helpful? That is KVM also connect to DP port via the dongle.

Hi TicTac1,

 

Thanks for your reply, it was not the answer I was hoping but at least I know it now.

 

I am going to use Digital dongles and replace all the analogue one.

 

It will be great to have this information somewhere and of course a BIOS settings to change the prioritization.
