External monitor on Imac

[Silversil]

Hi everybody.
I have a mid-2010 Imac and I have linked to it a Wacom Cintiq trought mini display port cable. I use the setting "mirror display" to see the same image on both displays.
Now my question is: can I add another external monitor ad use it to see another image respect to the image visualized on Cintiq and Imac displays?
Tnanks to everybody.
Bye

I think you may only use one external monitor on the 2010 imac.

I have a 24" external on my imac (older than yours) via mini dvi port but no t mirrored. I have them independent.
The port will only support one monitor.

Hi, thanks for your reply.
I founded this discussion on another forum:

My GPU is ATI Radeon HD 5750 102MB

But I don't undersant how I could do it..

From my readings an imac GPU is not the same as a card in say a mac pro.
as such the imac card does not support the eyefinity for triple monitor use.

It does not look like you can run triple monitors on your current hardware.

Not sure if this video will help you specific situation or not.

Looks like it requires some additional hardware and software updates. Does not work out of the box.
