Step1.First of all you have to set up all three monitors using ati eyefinite... three of your monitor will display only one screen.... step2.then you need to split those three monitors as three screen(such that each will display three different programs)using hydra vision...
if you like to use your three monitors as three screen displaying same thing on three of them then you simply need to plug three monitors to your card(no eyefinte and hydra needed)
