so i saw your 24 screen eyefinity using 4 cards and was inspired to build a 9 screen photobooth for my work in a 3 x 3 grid
I did my research and purchased 2 x 7750 eye 6 cards giving me a total of 12 mini dp outputs
Now I can get 6 screens running from one card in a 2x3 but cant get the 2 cards to work together to make 3x3
if i use the 15.x.x drivers I can use 2 cards , 3 screens from 1 and 2 from the other card but im limited to a max 5 screens
if i use the latest drivers i can only use 1 card and a max 6 screens
I have tried windows 7 x64, windows 8.1 and windows 10
Kind of stuck now not sure how you got 24 screens running off 4 cards when the latest drivers wont allow two cards to work together
appreciate some help making my 3x3 !
