Optiplex 990 Multi-Display settings in BIOS

This question has been answered by acmd9

Hello,

does anybody know what the bios setting "Video" -> "Multi-Display" -> "Enable Multi-Display" effect? It just says "This option enables or disables Multi-Display. It should be enabled for Windows 7 32/64-bit only. This feature is not applicable to other operating systems."

By default its disabled.

I am using a HD 6450, not the onboard video.

 

Thank you

Daniel

  • I had this same question and here is the answer from a Dell support chat:

    ... this model does something different from our other systems in regards to onboard video and video cards.If you have that setting enabled, and a video card installed, and you're running Windows 7 with both drivers installed, you can use both the onboard video and the additional card

  • When  combining a dual monitor card with the integrated video port offer the ability to run a three-monitor set up? I have tried to install two video cards to set up a three monitor set up and it failed.

  • All this means is that you can use the displayport and vga at the same time for 2 different monitors.  I have a ATI 6670 and it completely disables the onboard intel video.

  • We are trying to run 3 monitors from an Optiplex 990.   Did this solution work?   I've tried installing 2 cards for the ability to run 3 monitors with no luck.  I can run 2 monitors from a single card plugged into the primary PCI express slot, but every time I plug in the second card into the PCI express slot #2 all three monitors go blank.

    If I can use the on board video along with a single card, we can live with it.  What are the required settings?

    I've also thought of purchasing a triple monitor capable card for my next step if the onboard and single card setup does not work.

    Any help will be greatly appreciated.

  • Cant use onboard with x16 video  get an ATi card with eyefinity and some mini display port adapters.

    While Eyefinity is a fantastic tool, it does have a couple major drawbacks in a budget-oriented environment. The most significant restriction is mandatory DisplayPort use. In a triple-display setup, at least one monitor must use the card's DisplayPort output. If one of the displays doesn't have a DisplayPort input, the user must purchase an active DisplayPort to HDMI/DVI/VGA converter in order for it to work. The active part is key because it means a low-cost passive converter won't work. Unfortunately, most active DisplayPort-to-HDMI/DVI converters seem to be in the $100 range.

  • Maybe you have the same problem I had.  I have the Two DUAL HD 6350 cards and found there is a setting called CrossFire that is on by default.  When I turned it off I was able to connect monitors to both cards.

  • Where is the switch setting?

  • It is in the Catalyst Control Center.  There may be other ways to get there, but here is how I found it.

     

    1. From the Catalyst Control Center Start Screen choose Performance - AMD CrossFire.

    2. Un-check "Enable CrossFire."

  • A different approach would be.
