No. The other guy reported the same issue but named his ports wrong (mixed them up). You can actually find evidence of him coming to that conclusion from a simple google search. He had the original post on multiple forum sites.
Just a reminder, and to clear some things up,:
-My cable is a DVI-D Cable. (all pins and dash sign).
-I am not having trouble running anything on 144hz. I have an asus vg248qe that outputs 144hz.
-When I plug in my cable to the bottom dvi port (which is a dvi-d dual link port), and run league of legends, the game looks ultra smooth and damn nice. However, it feels slow. like there is some kind of input lag or something. It actually affects my performance.
-When I plug in my cable to the top dvi port (which is a dvi-i dual link port), league of legends feels a lot more fast while playing, just a lot more reactive and crisp feeling.
