My video card has displayport & DVI-I. I used this picture. I have:

  • DVI-I to VGA (Currently use this to connect Acer monitor)
  • Bizlink (Active Display Port to DVI-D) Cable. View
  • DL-DVI-D to VGA adapter
  • First display: Acer G225 HQ (VGA & DVI-D port)
  • Second display: Dell 19 inch monitor (VGA port)

I want to use dual monitor. But I'm connecting video card to bizlink, DVI to DVI, and Dell monitor.

My video card can support multimonitor. Geforce GT 330 Review

How can I connect a second monitor?

The way you describe it is confusing, but it sounds like you're trying to connect the Dell monitor via VGA, through a DVI-D adapter, through a DisplayPort adapter, to the DisplayPort connector on the card. This will not work because DVI-D is digital only. You need an active digital-to-analog converter somewhere along the line, that's what an adapter like that is intended to be used in conjunction with. I'd just buy a DisplayPort to VGA converter (which generally don't need external power beyond what the DisplayPort provides itself, which is a nice bonus).
