HDMI Over Ethernet Adapter Extends HDMI Connections Up to 98
Feet, Saves MoneyS  HDMI is a great technology, but if you have
to run the cable over long distances they're not the most
reliable. Ethernet cable (or, more correctly, Cat5e/Cat6 cable),
on the other hand, is better at traveling many feet. It's also
cheaper. The solution? Use an Ethernet cable to extend your HDMI
connections. All you need is this little adapter.  As Apartment
Therapy Tech points out, the cost of running HDMI over long
distances is about 80 cents per foot, whereas Cat5e/Cat6 is only
15 cents. Seems like a pretty good deal.  UPDATE: Some people
feel it's better to just pay up for the expensive, lengthy HDMI
cables, and here's why. We're not saying one way or the other is
correct/best, but just want to provide you with both sides of
the story so you can make an informed choice.  HDMI Extender
