fyi, I'm running 30FOOT lengths of hdmi to my projector and a tv in an adjacent bathroom out of my powered splitter, that would apparently be about the max. I rearranged the room, which required me to add a 15ft extension to the cable going to the bathroom, and it no long works properly. it will NEVER work if any of the other displays are on, and it only works about 25% of the time if it's the only display on. I haven't quite figured out what the issue is, it seems to work ok for my computer desktop, but not at all for video.
for a 22 meter run, it's probably cheaper to buy a second source, or maybe one of the wireless transmitters will work over that distance(still pretty doubtful though). that hdbaset or whatever it's called is crazy expensive, and seem to be what's required for those kind of lengths.
