late model 2009 imac27/ 1900x1200
I have a late 2009 imac with ATI Radeon HD 4850 512 MB.
I am running an HPLP2475w from the display port at 1200x1920.
I want to add a Cinema Display 23" at 1920x1200.
I am running Lion 10.7.2.
What adapter should I buy for usb to DVI? (or should I go another route)
