I'm pushing a heavy gauge flat Monoprice cable (24AWG) to the limit at 35 feet. No problems so far. I think some early cheap HDMI cables had problems, but it is hardly new technology now and even BlueJeans says that most cable works fine until you get to long runs.

Monster is just leveraging its name recognition and in-store placement agreements to charge absurd prices. Return it.
