A:AnswerThis cable is intended to convert the mini-display-port(thunder port)(Mac) to hdmi. This cable is specifically for that, not for another computer type. That being said the cable is useless for the intended purpose.
A:AnswerIf you are looking at a mac yes it is supposed to be for 4k however you will be better off getting the adapter from thunder port(aka mini display port) to hdmi and just getting a straight hdmi to hdmi cable. Not trying to give a strict negative response about this product, but due to the recent update to mac OSX it is useless for any Mac user.
A:AnswerIf your tablet supports HDMI or Mini DisplayPort connection, then this cable will work with it, Roger. Check out this link for more product information, http://www.belkin.com/us/F2CD080/p/P-F2CD080/.
