three technologies, HDMI, DVI and Displayport are all commonly
used today for connectivity of video and audio
capability is for only video and therefore it is used only
for computer displays and monitors. HDMI has become the
standard today for all devices requiring both video and
audio with one simple and compact cable and connectors.
Most devices today have HDMI and this includes all television,
and related video/audio equipment which work in the home
is a digital display interface developed by the Video Electronics
Standards Association (VESA). The interface is primarily
used to connect a video source to a display device such
as a computer monitor, though it can also be used to transmit
audio, USB, and other forms of data.
VESA specification is royalty-free. VESA designed it to
replace VGA, DVI, and LVDS. Backward compatibility to VGA
and DVI by using adapter dongles enables consumers to use
DisplayPort fitted video sources without replacing existing
display devices. Although DisplayPort has much of the same
functionality as HDMI, it is expected to complement the
interface, not replace it.
is becoming the industry replacement for outmoded display
technologies such as DVI, LVDS and VGA and it”¦s currently
being built into all new PC chipsets, GPU”¦s and display
controllers from major silicon manufacturers. DisplayPort
utilizes a state-of-the-art digital protocol and provides
an expandable foundation to enable amazing digital display
experiences. Designed for low power implementation and high
performance, DisplayPort enables the next generation display
technology while providing compatibility with existing equipment.
Designed specifically for usage in space-constrained applications
like ultra-thin notebooks, netbooks and graphic cards where
connector space is at a premium and where display performance
HDMI and DisplayPort are designed as scalable solution for
high performance digital display connectivity. Both enable
the highest resolutions, the fastest refresh rates and deepest
color depths over standard cables. DisplayPort has unique
features and capabilities that enable exciting new types
of displays and display usages. And it doesn”¦t require
PC owners to replace all of their equipment because simple
adaptors allow DisplayPort enabled devices to connect to
monitors and projectors that use older technologies.
Licensing, LLC announced on October 25, 2011 that there
were over 1,100 HDMI Adopters and that over 2 billion HDMI-enabled
products had shipped since the launch of the HDMI standard.
From October 25, 2011, all development of the HDMI specification
became the responsibility of the newly-created HDMI Forum.
