If either of your inputs is a game console you're going to want > 4.95Gbps:
HSYNC: 1920+280 (horizontal blanking pixel No.)
VSYNC: 1200+50 (vertical blanking line No.)
total pixel per frame = 2200x1250 = 2.75 Mpx/frame
Bit rate = 2.75 Mpx/frame x (3x8) bit/px x 60 frame/s = 3.96 Gbit/s
TMDS: 8 bit -> 10 bit
TMDS bit rate = 3.96 Gbit/s x 10/8 = 4.95 Gbit/s
Most blurays will require much less, since they are 24 frames per second...about 2.5Gbps
If you plan on running 3d 60fps, it'll take 9.9Gbps of bandwidth.
HDMI 1.4 and HDMI 1.3 Category 2 Are both certified to those speeds (if you're shopping at a brick and mortar store, look for both of those things)
