OK, what are you saying? you still don't believe HDMI supports 1080p@120Hz
Here is official HDMI website linkhttp://www.hdmi.org/learningcenter/faq.aspx
Here is the quote from their website:
Q. What is the difference between a Standard HDMI cable and a High-Speed HDMI cable?
Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables.
Standard (or category 1) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.
High Speed (or category 2) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).
end of quote.
Discussing HDMI handshaking protocols is out of topic, me not go there, but as the website said, you can do whatever you want with the signal (increase color depth, increase FPS, or resolution) as long as you stay bellow 10.2 Gb and that's good for about 120Hz @1080 and overhead.
