multi display monitor

[Constantinos Hadjikostas]

Hey,
I am using 2 cards R9 280 via crossfire and i want to have more than one display. I wonder what is the maximum numbers of displays that i can use with my hardware?

What specific card are you using? This is usually down to the number of outputs of the card. Remember all monitors will connect to the top GPU. If I am correct about this then you could connect six monitors however I doubt your card will have that many outputs.
Also what are you trying to achieve? Eyefinity or just more Desktop space.
