I'm not quite sure what you are asking.  In addition to the number of links on
the chip itself, you are limited by how the board is wired up.  E.g., if your
board only has one DVI port on it, you are limited to 1 dual-link DVI display
since HDMI does not support duallink and DP requires an active adapter to
support duallink DVI.
