I just purchased an Eizo 30" multiscan 2560x1600 to use on my MacBook Pro 2010, and I also purchased from MonoPrice the mini displayport + USB to dual link DVI adapter, I read many stories on the original from Apple, but it does not work properly.
The MacBook Pro recognize the monitor and its resolution of 2560x1600 and when I select this resolution the monitor displays a poor image, like blurred and letter rendering are horrible, I need to go back to Apple resolution 1920x1200. Could you assist?
