RE:Redmere active HDMI Cables work with ViveHere's some further proof, nice table which cables are tested and work: https://www.reddit.com/r/Vive/wiki/cables Apparently passive HDMI cables work only upto 5m/15ft. with the Vive, which is probably too short for many users. Among the longer active HDMI cables tested working, three brands explicitly state Redmere chips included (Monoprice, Ligawo, Redhead). Not sure about the others, but certainly this looks favarable for Spectra7.
