George from Toronto, Canada
HDMI

George is a system integrator and he knows about wireless HDMI. George says that video scalers like DVDo.com have wireless HDMI 60Hz solutions that work really well because it handles spectrum that isn't used much. It works great -- up to 50 feet. And the walls aren't really an issue. George says that doing it through Cat5 or Cat 6 and baluns work as the best option in that case.
