I have the R9 280x Matrix Platinum from Asus and i cant seem to be able to set up eyefinity on 3 screens it works on 2 and it wont go any higher i have reinstalled the drivers and the bios for the card and it still cant do 3 screens my friend says that it is because it is a non reference card as it uses 4 display ports and i have 3 asus vn247h and currently going to see if i can buy a gtx 780 6gb but before i do i want to get the r9 280x working so that i dont have to buy a new card i have installed the drivers from amd's web sight and even asus's amd drivers for my card and i still cant get 3 screens working and as Logan got a 7970 with the same vn247hx3 which uses the same layout i was wondering how he set it up and if i could get help.
Thanks
