As we've just eluded to, HDMI has had a tonne of versions over the years, each offering up an increased level of bandwidth that allows for the transfer of higher resolutions and refresh rates.
HDMI has come a long way since the original arrival of HDMI 1.0. The latest iteration of HDMI offers up to 10 times the data transfer of the original standard, keeping up with the ever-growing performance of both consoles and PC hardware.
