I remember a thread about HDMI length limits here in the distant past; I think Trevor has successfully run 1080p over 50' cables but possibly with not quite 100% reliability?
Adam remembers correctly: I did many installs with DVI over 50' cables at "normal" rez's (like anything under 2550x1440). And a couple of DVI-HDMI cables (they exist) at 50' too. Since DVI/HDMI is almost the same thing signal-wise, I would expect HDMI/HDMI at 50' to be fine too. Never tried 100'.
Since a 50' HDMI cable is fairly cheap compared to an active HDMI/ethernet repeater, start with the cable. Heck, maybe even 100' will work, let us know!
If you have to go the active repeater route, I would expect everything designed for that purpose will work perfectly fine. There will be a tiny delay, though, with all those conversions (few ms?). Might be enough to bother a hardcore gamer.
(You think stringing HDMI through walls is tough, try DVI!!)
