We haven't had nearly as many issues in with HDMI as reported by some (or maybe most) members here.

What brands/devices are causing you guys the most issues? How long are the runs that cause you guys issues on average?

I'd really be curious to know.

I'm fine with HDMI but If I were to replace it with something it'd be Ethernet. JAP is pretty cool but I've yet to have a chance to try it. What'd be awesome is if all devices (sources and displays) could plug into a network (this would either be the same as the house network or a separate network altogether). Then each display could choose to poll from a source on that network. You'd have easy to terminate cabling and it'd be through a standard all (hopefully) installers are already familiar with.

Far-fetched idea, though!
