Higher speed: although all previous versions of HDMI have had more than enough bandwidth to supports all current HDTV formats.
HDMI increases its single-link bandwidth to 340MHz (10.2Gbps) to support the demands of future HD display devices, such as higher resolution.
Deep color: HDMI supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) color depths, up from the 24-bit depths in previous versions of the HDMI specification, for stunning rendering of over one billion colors in unprecedented detail.
