resolution issue with 30" DVI connected to retina MBP
I am unable to get HD res on a 2010 Apple Cinema Display 30" DVI when I connect it to my retina display Macbook Pro.
Can anyone help? As the display setting aren't giving me any options over 1280x800 and the external monitor is an HD one.
Thanks,
Simon
