Dual Monitor with Radeon Sapphire HD 7770 GHz Edition, is it possible?

If yes, how? (He plays with a PC)

I'm writing on behalf of my brother, we are both quite rookies about computers so I apologise if the answer is noobish!

I think they support up to 6 displays with the Eyefinity feature. Depending on what display connectors do you have on your card, but for example you could use a DVI and a HDMI cable.

And why when he plugs in the second monitor nothing happens?
he can't setup anything because anything appears.

 

[VicVega1]

I think you have to set them up in Catalyst Control Center or Display Properties in COntrol Panel first.
What connectors did you use?

 

[davideeeeh]

He uses a VGA connector for both monitors

and which signal ports of the graphics card are used?
If one of the monitors is connected with a DVI-D or HDMI port it won't work without a converter, since VGA is analog and HDMI/DVI-D are digital.
What are the exact models of monitors?

EDIT: ok, I see the video card has a DVI-I, HDMI and Display Port 1.2 available, so you must be using a converter of some sort. What's the setup? which ports are you guys using?
