Connect a third monitori into my pc

I have a ATI readeon 5800 series graphics card, Windows 7, and trhe monitor.
First monitor i connected through dvi cable.
Second monitor i connected through vga cable.

And i tried to connect third monitor through hdmi/dvi cable(http://www.jdr.com/interact/item.asp?itemno=CBL-HDMI-DVI)

And windows keep saing the error "unable to save display settings." http://gen.cubik.ee/displayError.jpg
And i tried this fix http://www.techmowgli.com/viewsearchresult.aspx?sid=588 but i dont have any TMM or MobilePC entries on regedit.

  1. Which card is it?
    I think that for most 5000 series cards, you need to use the DisplayPort to connect to one of the monitors. You can get a displayport to vga adapter for about $30.
    For me, my card has 2xDVI, 1 HDMI, and 1 Displayport - I used the 2 DVI and an adapter to go from Displayport to VGA.
  2. ok, now i reconfigured my monitor, i discovered my montor have HDMI inputs.
    Now i connected my main monitor through hdmi and scondar monitor through DVI
    and i have one free DVI and i used this to connect third monitor, but still the same error.
    I dont think so that proble is on monitors or cables.

    Instead of Windows, try using ATI Catalyst Control Center (make sure your Catalyst drivers are up-to-date) to make your changes. I would also avoid that HDMI/DVI cable, I have used one before and it can act funny depending on your graphics card/monitor.
  4. tied ACC, but but no use.
    But is the ati card supports 3 monitors at once

    You cannot connect 3 monitors on Eyefinity without atleast one of them being a Display-port connection. If you monitor doesn't support display-port there are some adapters out there for display-port ~ dvi that you can buy.

    Can you whow me on google what is a display-port connection adapter
  7. Although I know nothing about this company the displayport adapter seem's to be what I had in mind

    Here's the newegg link for a displayport-dvi adapter
  8. ok, thanks
  9. No that won't work decode. Just look at the review.

    Pros: It works for what it was designed for.

    Cons: Well if your planning on using this with a 5xxx series ATI Card, It will not work to get you to use your 3rd monitor. It's not a powered one, thus the card can't handle it. Check out dell's DP2DVI Converter, however it'll set you back about 100 bucks.


    As far as I know you need one of those expensive active adpaters.

    I could be totally wrong, but thats what I've seen....
  10. Don't buy one of those active adapters! ATI has heard you and is releasing a solution:

    Hope this helps :)
  11. If one of your monitors supports VGA, you can always use a VGA>Displayport Adapter. I've tried it and it works fine.
