As far as display compatibility
is concerned, HDMI supports
every uncompressed standard,
enhanced, and high definition
video format including the older
PAL format.
Furthermore, HDMI’s high
definition television
resolutions supported are 480i,
480p, 720p, 1080i, and 1080p.
Most standard PC monitor formats
are also supported by HDMI.
These include
VGA,
XGA, and
SXGA at resolutions of
1600x1200 and beyond.
HDMI also supports uncompressed
audio formats and compressed
audio formats including Dolby
Digital, Dolby Digital EX,
DTS, and DTS EX. Following
the DVD-Audio standard, HDMI was
built to handle 1-8 uncompressed
audio streams and has sample
rates of 48, 96, or even 192
kHz. Compressed multi-channel
audio streams can also be
handled at sample rates of 192
kHz.
Fortunately for those with
numerous DVI devices, HDMI is
backwards compatible with these
and devices using the
EIA-861
DTV profile. The additional
features of HDMI, however,
including digital audio and
Consumer Electronics Control (CEC),
will not work on these systems.
