To set it up you need an ATI card with "eyefinity"
Catalyst Control Center software (comes with ATI cards)
and of course 3 monitors.
All 3 monitors or tvs combine to become one "long" monitor, so it is very important that the resolutions are at least "close" to each other or it looks stupid.
youtube "how to set up eyefinity" will get you a lot of good results on the steps to set it up.
An example of FRAPS video of me playing on eyefinity: http://www.youtube.com/watch?v=Zbaavhg0IaA Edited, Jan 11th 2011 9:02pm by DoctorMog
