My eyefinity stopped working, I Have 2 SAPPHIRE HD 7870 GHz Edition OC 2GB in crossfire and have 3 iiyama monitors set up, when i first set up eyefinity it worked fine playing bf4 and got 60fps on medium settings and when i got out of game the left screen went black all of a sudden so i swapped around cables and there was always one monitor black so i updated the amd software and now it only gives the option for setting up eyefintiy with 2 monitors even though there are 3 connected, i have swapped around cables at the back using 2 dvi and a mini display port all coming from the same GPU and still no results. Any suggestions on a fix?
