30" nec 3090WQXi 2560 x 1600 support on 15" macbook pro

My question is, can this be done?

My machine is the older 15" macbook pro, 2011 generation, with the 2.4GZ processor and i7 processor.  I have 2 usb and 1 thunderbolt ports.
I have the apple thunderbolt to mini Dvi plug.  When I attach the NEC 30" the max resolution I can get is 1900 x 1080.  Apple told me that is
due to the thunderbolt to mini-dvi plug, in that it only supports external resolution up to 1900 x 1080 and that if I need to go higher, I have to
have a Thunderbolt enabled monitor.  The rep I spoke with said that even if I had a HDMI connection on the back of the monitor which I don't,
I would still be limited to the 1900 x 1080 since I am going from thunderbolt to HDMI.  

I just am curious about this, and wanted to double check.  Nothing wrong with the NEC 30", but it seems strange to me that I can't get the correct
resolution on the monitor from the macbookpro.  

Any hints or help would be greatly appreciated.

you need MDP to dual-link DVI adapter

Thanks, that got it working,  I had asked the apple tech support if that was the correct adapter, but they kept telling me that no matter what, I would not get the
2560 x 1600 unless I used only a thunderbolt monitor. 

Works fine with correct resolution with the correct apple adapter.
