I recently switched from a penryn MBP to a Unibody one. I was using a DVI-HDMI adapter to connect it to my HDTV. With the new computer I purchased a Mini Display port adapter and HDMI cable and connected it to the same TV. There seems to me to be a noticeably poorer quality to the HDTV picture now than there was with the older set up. Has anyone else noticed anything similar? Any thoughts on why? Thanks.
