Hello there I have some trouble connecting my monitor (Samsung S27A550H) to my MacBook Pro 7,1, 13" (NVIDIA GeForce 320M). I do have a HDMI to mini displayport cable. But when I connect them, the quality of the monitor is not HD, it is blurred. Could it be that my 13" cannot send an HDMI signal? Or is the NVIDIA GeForce 320M not good enough?
