Digital video cables are used for transmitting digital video signals from one video source to other output media like LCD projectors, LCD televisions, and computer monitors. They are composed of pin connectors arranged in different types like HDMI, DVI, DFP, and P&D. They can display videos up to 720p or 1080i resolutions. Some digital video cables can transmit analog and audio signals aside from digital video signals.
Types of Digital Video Cables
Kinds of Digital Video Cables include the following:
HDMI (High Definition Multimedia Interface) digital video cables
HDMI digital video cables are used for transmitting uncompressed video and audio signals in one cable.
They can transmit multi-channel audio and high bandwidth video for excellent sound and resolution.
They come in six- to 15-foot lengths.
They can be used with LCD projectors, DVD players, and LCD televisions.
DVI (Digital Video Interface) digital video cables
DVI digital video cables are used for transmitting both analog and digital video signals.

They come in six- to 15-foot lengths.
P&D (Plug & Display) digital video cables

Choosing Digital Video Cables (Buying tips)
Connector: Choose a digital video cable with gold-plated connectors for resistance to corrosion and rust, and for efficient signal transmissions.
Compatibility: Before buying a digital video cable, check if it is compatible with your computer, laptop, LCD projector, or other electronic device. Some digital video cables can only be used for certain devices, so consult your cable manufacturer for a list of compatible systems.
Length: For home and office use, choose a digital video cable six to 15 feet long, as one longer than 15 feet can produce video distortions. However, if you really need a longer digital video cable, test its output quality at the store. You can also do a brand comparison to know which one works the best.
