    What's the crack with SLI cards and their DVI cables?

    My m8 just got his new £1500 pc and he can't get any signal into the monitor. The monitor works cos it displays a message saying "no signal". The computer turns on, both graphics cards fans are spinning.

    There is a normal 'blue' monitor connection/cable, and a one that's apparently for DVI input. However, the 2 grahics cards only have 2 ports each that are both the DVI cable type so for the 'blue' cable an adaptor has to be used to get it to plug into a card.

    Is there a specific combination that the cables have to be plugged in? Seriously have no idea why the computer won't work :(

    The irony of someone buying an SLI rig but they can't even get a monitor to work is more than a little funny.

    Maybe an xbox 360 would have been a better purchase. :lol:

    Do the graphics cards have 2 dvi ports each (total of 4 visible)?

    Have yor tried the dvi - vga adapter in each of the four dvi ports?

    I'd try turning to pc off, plug ther cable into each one, restart the pc.

    Keep doing this until you see the 'post' screen.

    If you can see the post screen but not the OS I'd boot the OS into safe mode (I think you press f8) and reduce the resolution (or if the screen is lcd set it to the correct res).

    If all of this fails you may have broken hardware.

    I do kinda feel that if your mate doesn't know this sort of stuff he's going to struggle to get the best out of this 1.5k sli pc but I could be wrong. :)

    also remember tht there are three types of dvi cable, dvi-d(digital), dvi-a(analog) and dvi-i(intergrated).

    dvi-d you can't just use an adaptor to convert to vga, because vga is analog and dvi-d is digital.

    You need a digital to analog convertor to do that so if your trying to convert this it won't work.

    To tell which type of dvi it is, you need to look at the one long flat pin if it has pins round it its analog, if it doesn't it dvi-d.

    I've never see a dvi pc graphics card that isn't dvi-i, I think it's standard.
