even though says for "mini" display port, will fit just fine in the "thunderbolt" display port. i have a macbook air and purchased so i could display videos on my tv from my mac. initially, video showed just fine without issue but i could only get audio from my mac and not tv. i read one of the other reviews and once i switched my audio sound source from my laptop to my tv it worked like a charm! i would recommend this product to anyone looking for a cable for this purpose!!
