Active or Passive DP adapter for DZ77BH-55K

I am about to purchase several DZ77BH-55K motherboards and plan to use two DVI monitors with them. This board has a HDMI and Displayport output so I wanted to know if the following configuration would work:

Display Port > DVI (Using a passive adapter)

HDMI > DVI

Both monitors will be set to a resolution of 1920x1080.

I found this Intel FAQ that say yes, this configuration should work with Passive adapters (albeit with a 3 montior config):

Question: Is passive dongle supported in 3-display configurations?

Answer:

Yes. Passive dongles are supported if the system manufacturer programmed the BIOS to support dual-mode interoperability (DisplayPort > HDMI, DisplayPort > DVI, DisplayPort > VGA).

Note See display combinations for valid passive dongle configurations based on the connected display.

So does this board have dual mode interoperability enabled in the BIOS?

Thanks,

Ali

Hello aliatgb, 

I understand that you are inquiring if the Intel(R) Desktop Board DZ77BH-55K will have dual mode interoperability enabled in the BIOS.

In regards to your inquire, it will support the dual mode interoperability and it is enabled by default.

Regards.
