Convert DVI-D to VGA
VGA (Video Graphics
Array) is a hardware specification for display monitors and computers that
allows a computer to display applications on a VGA-based monitor via a VGA
cable. VGA technology is one of the oldest forms of display hardware in
computing and is outfitted in virtually every computer system in the world. VGA
uses analog signals but is compatible with most digital devices. While DVI
technology has superseded VGA technology, both specifications are often
included in personal computers, with VGA technology being much more common in
laptop computers than desktop computers.
What is DVI-D?
DVI (Digital Visual
Interface) is a hardware specification for computers and display equipment that
is similar to VGA. DVI-D (Digital Visual Interface Digital) refers to DVI
technology that is used exclusively with digital devices, while other versions
of DVI can be used with analog devices. While VGA technology was made for
analog computers, DVI technology is more modern and is intended for digital
computers and display equipment, such as monitors and projectors. While VGA and
DVI produce similar quality on regular monitors, DVI produces much higher
picture quality on LCD monitors and other high-definition equipment.
How to Convert DVI-D to VGA
In order to convert
DVI-D to VGA, either a DVI-D to VGA conversion cable or a DVI-D to VGA adapter
must be implemented. DVI-D to VGA conversion cables and adapters are similar
but the conversion cable allows the user to separate the devices over a short
distance while the adapter requires the devices to be back-to-back. Most
display devices have their own cable, allowing the user to connect the adapter
to a DVI port and use the VGA cable to bridge the distance between the two
devices. Either method allows the user to convert DVI-D digital signals into
VGA analog signals so that a DVI-D source device can be used with a VGA output
device.
Applications
A user may wish to
convert DVI-D signals into VGA signals if he/she is using a DVI-D computer and
a VGA monitor or projector. DVI-D technology is found in most modern digital
equipment and should be used with a DVI-D output device, such as an LCD
monitor. However, if the user’s output device is older than the source device,
it may depend on analog signals and not have a DVI-D port.
