External display res. issue:

Hello all, my first post, I usually find answers by searching but this time I need help. Thanks in advance.

I have a MBP 15" Early 2011, just got a like new DELL 2711 display, I do photography so I wanted something bigger to replace my 23 Cinema Display. I got the apple mini display port to DVI adapter as well as the mini display port to HDMI.

I did a search before I got the display to check the max output resolution on over the mini display port out of my mac, apparently it is 2560x1600...

The think is, I can't select anything over 1920x1080 using the miniDP to DVI and that is what I had on the old apple display...

Any help would be greatly appreciated.

 

Hi,

Thank you for the queck reply, this is something new to me... what is the USB for if I may ask...

Could I use something like this instead since the DELL has the displayport?

Thank you guys for all of your help and input. I need to source out this cable now, one with good feedback and one that is available where I live.
