i have compared ,there is a little bit difference.
with same tv , same video card and different cables.
the more expensive cable is better than other.
the specification is the words' shadow. the expensive one seems sharper.
but, not so much difference , and at the same time the difference not only depends on your tv or monitor, but also cables.
the monitor + video card + cables = the performance!
same card, same web page.
but the hdmi version is actually different.
the expensive is 1.4 ,the other is 1.3.
the expensive one is thick. it contains more lines i think.
the more lines provide better and more correct signal.
maybe. so many items which are not sure.
