HDMI is a high-resolution multimedia interface, it is used in new models of computers, laptops, TVs. It relates to methods for the qualitative transfer of digital information. This connector connects a personal computer and a TV, while not only the image, but also audio information is transmitted through the cable. Therefore, the interface mentioned is so popular.
The purpose of the adapters
Such devices are used more and more often. We can say that today HDMI is the most advanced interface. An HDMI-to-DVI adapter cable is used when it is necessary to transmit high-quality digital video. This device allows you to connect digital signal sources to receivers that may not have this type of connector at the same time. As a result, digital signals can be transmitted without loss of definition. Such a transfer can be made from a personal computer to a television or projector. In this case, switching can be carried out for any devices that are equipped with interfaces of this type.
How to connect a DVI-HDMI adapter cable
Both of these interfaces are fully compatible. This means that it is possible to connect the device to a personal computer monitor via the HDMI port. Connect the DVI-HDMI adapter cable in the following order. First, turn off both devices. Next, through a video cable, the TV is connected to a personal computer. The end of the cord with the plug is connected to the output of the PC (or laptop), and the other to the TV. After that, the first turn on the TV. Its work is determined by the light flashing of the screen, showing the loading of Windows from the included computer. The video cable can also be combined with the old interfaces of the DVI digital video format. To do this, use the DVI-HDMI adapter. True, you should pay attention to one point: such a connection will have no audio signal, since the DVI format does not support audio transmission.
Specifications
These adapters meet the standards of both interfaces. They have excellent conductivity and high throughput characteristics at high frequencies. The conductive part of such a cable does not contain oxygen copper, so the transmitted signal reaches the receiver without distortion. Moreover, these products use four-layer shielding technology. It eliminates the possibility of exposure to transmitted signals of electromagnetic and magnetic interference. DVI and HDMI connectors have gold-plated contacts, and special protective caps are put on the plugs. In addition, such a cable is necessarily equipped with ferrite rings. The standard length of the product in question is three meters. The cable has two plugs: HDMI (19pin) and DVI-D DualLink (24 + 1pin). It supports picture resolution of 1920x1080 (1080 p).
HDMI to DVI adapter
Such a device has the overall dimensions of no more than a standard matchbox. It has the following design: HDMI plug and DVI jack. When buying a DVI-HDMI adapter, you must first determine which cable will be used to connect digital devices. And already based on this information, you should choose an adapter. To transmit audio signals, you can use a separate cable (if you have an audio, video receiver, it is recommended to give preference to a digital connection). The main advantage of such an adapter is the absence of quality loss in the transmitted image. This is very convenient for owners of Full HD or HD Ready TVs, since you do not need to additionally purchase a Blu-ray player or media center to watch high-resolution movies. If you have a personal computer or laptop with DVI connectors, you only need to buy an inexpensive DVI-HDMI adapter. And you can enjoy watching your favorite movies, video clips from your PC on your TV in perfect quality.
