Dual vga monitors on DVI-I and DVI-D

Alw1n used Ask the Experts™
I am running Win 7 x64 on an intel DQ45 m/b which supposedly has dual monitor support. The video ports are DVI-I and DVI-D and the kit came with one DVI-I->VGA adapter. I have two LCD monitors (vga only) so obviously could not connect both, so I bough a DVI-D->VGA adapter.
I have downloaded the latest drivers from Intel (GMA4500) and have both the monitors connected to the DVI 'I' and 'D' ports respectively but when doing graphics 'properties' I only ever get the option for 'single monitor' and only the monitor using the DVI-I adapter works.
Has anyone else tried using a DVI-D to VGA adapter in this scenario?

From what I'm reading on the internet DVI-D is pure digital format and the signal would need to be converted to an analog signal before VGA monitor would pick up the signal.
Below is a review page for a DVI-D to VGA converter, I think they ran into the same problem.


"In order to convert a DVI-D signal, which is  digital only, to a VGA, which is analog, you would first need to use an  adapter that converts the digital signal to an analog signal.  This  device alone will not allow you to connect a vga monitor to a DVI-D  video card.  If you have a DVI-I video card, it may be possible but with  a different product."

Also, I read up on the reviews on Newegg, people are saying the same thing about this...

You cannot convert DVI-D  to VGA with this item.  You actually need a convertor box which run  about $200.  Best thing to do is get a new monitor or new card.Cons: If you can't and have no options, google  DVI formats to get more guidance.


Thanks, just by virtue of the fact that mine doesn't work I would agree with the comments in the links you sent.

The marketing of these converters is quite deceptive as it would appear that they are useless for their assumed purpose.
The motherboard's marketing is more deceptive because 'dual monitor' can only be used when one of the monitors supports digital video (which I am sure the majority of consumer items currently don't).
