This means that they cannot play HDCP content at a resolution higher then what can be attained through a single DVI connection. The G80 cannot play HDCP content on a double-link, or two DVI, connection. And so, anyone buying an HD DVD or Blu-ray player, each which require an HDCP decoder, cannot view content at much higher resolutions then 1080P (1920x1080). R600 allows for HDCP playback on a dual link connection, which translates to a maximum playback resolution of 2048 x 1536.

newtekie1It doesn't matter, 1080P is good enough, that is what the content is at so anything higher is just taking a 1080P and stretching it. You can take a 640x480 picture and stretch it to 2048x1536, but it will still look like a 640x480 picture.
