Hi, someone tried to work with wireless hdmi? wanna try it, but not sure that it'll work
In case you did not follow all the previous 19 answer discussion, this is an Arduino forum. It has been explained in detail that HDMI is a technology relevant to current PC-type computers extending down to the capabilities of the Raspberry Pi and similar machines. 
But an Arduino in no way resembles a Raspberry Pi, and these fora are for the discussion of Arduinox and electronics that may be used in association with them, so while some people do use an Arduino in association with a Raspberry Pi, discussion of HDMI is clearly neither relevant nor appropriate here.
