Qhov no yuav ua rau cov LCD TVs tau txais 10.2Gbps cov ntaub ntawv xa mus, thiab 1.3 version ntawm kab yog tsim los ntawm plaub khub ntawm kev sib kis, uas ib khub ntawm cov channel yog lub moos channel, thiab lwm qhov peb khub yog TMDS raws (tsawg kawg. Kev sib kis ntawm cov teeb liab sib txawv), lawv qhov kev sib kis ceev yog 3.4GBPs. Tom qab ntawd 3 khub yog 3 * 3.4 = 10.2 GPBS muaj peev xwm nthuav dav 24-ntsis xim qhov tob txhawb los ntawm HDMI1.1 thiab 1.2 versions rau 30, 36 thiab 48 ntsis (RGB lossis YCbCr). HDMI 1.3 txhawb 1080 P; Qee qhov kev xav tau tsawg dua 3D kuj tau txais kev txhawb nqa (txoj kev xav tsis txhawb, tab sis ua tau qee qhov ua tau).

HDMI 1.4

HDMI 1.4 version tuaj yeem txhawb nqa 4K, tab sis raug rau 10.2Gbps bandwidth, qhov siab tshaj plaws tuaj yeem ncav cuag 3840 × 2160 daws teeb meem thiab 30FPS ncej tus nqi.

HDMI 2.0
