all ATSC HDTV standards and supports 8-channel digital audio, with extra bandwidth to
accommodate future enhancements. HDMI has two types of connectors. Type A and Type B. Type A
and Type B connectors use 19 pins and 29 pins, respectively. The Type B connector is designed for
very high-resolution displays that are expected in near future.

come with a 15-pin VGA connection cable, even if they are capable of handling digital signals coming
from DVI connections. However, some monitors come with both types of cables. DVI has three main
categories of connectors. They are. DVI-A, DVI-D, and DVI-I. DVI-A is an analog-only connector,
DVI-D is a digital-only connector, and DVI-I is an analog/digital connector. DVI-D and DVI-I
connectors are of two types. single link and dual link. DVI supports UXGA and HDTV with a single set
of links. Higher resolutions such as 1920 x 1080, 2048 x 1536, or more can be supported with dual
links.
