Four monitors with two HD 6870s. Second card undetected?

  1. I dont want to run my cards in crossfire, but instead have each card run two monitors. I installed my cards plugged all 4 monitors in, booted up, installed drivers, and restarted.

    I cant detect my two monitors plugged into my second card. Im not sure if that means my second card is not being detected, or if i need the crossfire bridge connecting the two cards.

    I know the monitors work, already tested. I figured i would try putting the bridge on the two cards but my 6870s didnt come with one, nor did my motherboard.
    Really dont know what to do here, ive always owned nvideas.

    Both cards seem to be running, both fans are going.

    I'd order a CFX bridge personally. Your running dual GPU's, so it makes sense to have them connected.

    Although I'm not sure if you are required to have the bridge in place to use the video output of another GPU. That said, a single HD6870 can run upto six displays anyway, at least mine can.
