Well, the HDMI 1.4 specification will support 3D tv and it's maximum frequency is stated as:
HDMI 1.4 was released on May 28, 2009, and Silicon Image expects their first HDMI 1.4 products to sample in the second half of 2009.[53][106] HDMI 1.4 increases the maximum resolution to 4K × 2K (3840×2160p at 24Hz/25Hz/30Hz and 4096×2160p at 24Hz, which is a resolution used with digital theaters); an HDMI Ethernet Channel, which allows for a 100 Mb/s Ethernet connection between the two HDMI connected devices; and introduces an Audio Return Channel, 3D Over HDMI (HDMI 1.3 devices will only support this for 1080i)[107], a new Micro HDMI Connector, expanded support for color spaces, and an Automotive Connection System.[53][108] HDMI 1.4 supports several stereoscopic 3D formats including field alternative (interlaced), frame alternative, frame packing, line alternative, side-by-side half, side-by-side full, 2D + depth, and 2D + depth + graphics + graphics depth,[50][109][110] with top/bottom half and full formats to be added in January 2010. HDMI 1.4 requires that 3D displays support the frame packing 3D formats at either 720p50 and 1080p24 or 720p60 and 1080p24.[110] High Speed HDMI 1.3 cables can support all HDMI 1.4 features except for the HDMI Ethernet Channel.[50][109][110]
So I can tell you now that you will not need 120Hz input - in fact, you only need 24Hz input for true 1080p 3D across HDMI using 4096×2160p at 24Hz.
