big problem to install my second monitor
 

I use from 1 year my 24 inches DELL monitor in sly mode with my 2 grafic cards geforce 7900 GTX.
I decided to use a second monitor and I have the 204B from samsung.

My second monitor never works and I don't know what to do ...

Re: big problem to install my second monitor
 

In my Nvidia control panel, advanced option, I have only one choice --> Only use one display ( Single )
I know there should be another choice ( Dual )

I downloaded again Nvidia drivers, but still only one option.
I tried both analog and digital for the 204B driver, I tried all 4 sockets, etc.
Why is it so hard to install ?
I spent about 8 hours today only with that.

Need Help tx

Edit: Believe it or not, I made a random thing 30 seconds after this post and it worked. Of course I tried this thing numerous times in these 8 hours.
Life is strange sometimes ...
