Does any one know of a cable that will connect the Lightning port on my IPad Air to HDMI. I already have Apple TV at home but I'm looking for a portable solution when travelling. I have a Wifi only I pad and all the cables I can find online only work with personal hotspot so are not compatible with my I pad. There are also plenty of cables that work with the old 30pin ports, it seem strange that there is a huge gap of wifi only lightning iPads that can't connect to HDMI. Any help or recommendations would be great.
