People who think they need monster cables for long hdmi runs are crazy, HDMI cables like any cable (digital or analog) can only carry a signal so far depending on specs of signal and gauge of cable. In the case of digital signals theres no way you get snow effect like somepeople claim in this thread, what happens is the reliability of the signal lowers you'll either get it or not.
You'll notice that longer cables on monoprice come in 22AWG thats because if you up the gauge, you reduce attenuation. Simply put 22AWG will carry that signal farther than 24AWG. At the same time the range of HDMI 1.0 vs 1.3 (340MHz) will be very different with 1.3 signals not going very far.
Better solutions like HDMI extenders via Ethernet (Cat6)
