I have two X9DRW-iF motherboards with Intel i7-3820 CPU installed, but both motherboards did not give video output with on board VGA port. Is there something I need to do to make them work?
You are using the wrong type of CPU. X9DRW-iF only supports Intel Xeon Processor E-2600 series (LGA2011). I7-3820/LGA2011 is not supported by X9DRW-iF motherboard.
