The advent of high definition television has increased the demand for DVI and HDMI. A DVI to HDMI cable can be used when a user wants to convert and relay video from a DVI source to a HDMI display device without the need for a converter. Use of these cables has no negative effect on video quality as the same high resolution will be maintained. As such, there is no difference between DVI and HDMI since both make use of digital video signals, but the debate regarding which is better is an ongoing one. Both these technologies use the same encoding/decoding scheme and can be connected by using these cables.

The major difference between the two is that while HDMI uses a different 19-pin connector which allows it to carry audio as well as video over a single cable, DVI only carries video over a single cable. Continue reading »

High definition multimedia Interface or HDMI as it is known is an audio video interface which transfers uncompressed digital streams over a single cable. The cables which are used to do this relay are HDMI cables. Available in two categories, category 1, tested at 74.5 MHz, known as standard and category 2 tested at 340 MHz and called high speed, these cables also fall in the two categories because of their specific lengths. Since both audio as well as video can be transferred over a single cable, it is also changing the face of the multi media and entertainment industry. A variant of this cable, the HDMI extension cable, supports standard HDMI video, enhanced HDMI video and high definition HDMI. Compatible with almost all digital display devices such as HDTV’s, plasma displays, LCD TV’s and projectors, these cables are referred to as the future of HDTV. Another variant is the DVI to HDMI cable.

If a user needs to convert video from a DVI source and present it on an HDMI monitor or display device and vice versa, they can make use of the DVI to HDMI cable. They perform the same action as the HDMI cable since they use the same encoding scheme. Continue reading »

Video Graphics Array or VGA, as it is commonly referred, is the graphics standard used in older computers. Even though many computers today still support this graphics standard, it also depends on the type of monitor being used. These days the cables which carry the display signals are referred to as VGA cables. Available in a wide range and at different prices, the more expensive models have gold plated plugs or shielding which prevent interference. However, experts believe that these expensive models offer almost the same image quality as the cheaper versions. The main thing which should be kept in mind while selecting these cables is the cable length. The length should be equal to the distance between the source and display devices as longer cable lengths can lead to Continue reading »

A compact audio/video interface for transmitting uncompressed digital data is the High-Definition Multimedia Interface best known as HDMI. The HDMI cables are ones which relay digital video, audio and control signals without any deterioration. All these signals are transmitted over a single cable and using these cables is a space saving solution. Used to connect a high-definition device to an HDTV, one end of the cable needs to be plugged into the HDTV’s HDMI input slot and the other end into the device’s HDMI output slot. Once this is done, signals can be transmitted and HDMI outputs received. These cables provide excellent Continue reading »
