DVI-HDMI adapter: description, purpose, technical characteristics of the device

HDMI is a high-definition multimedia interface, it is used in new models of computers, laptops, TVs. It refers to the methods of qualitative transmission of digital information. This connector connects the personal computer and the TV, while not only the image but also the sound information is transmitted through the cable. Therefore, this interface is so popular.

Assignment of adapters

Such devices are used increasingly. We can say that for today HDMI is the most perfect interface. An HDMI-to-DVI adapter cable is used in cases where it is necessary to transmit a digital video signal in high quality. This device allows you to connect digital signal sources to receivers that may not have connectors of this type at the same time. As a result, digital signals can be transmitted without loss of clarity. This transfer can be done from a personal computer to a TV or a projector. In this case, switching can be performed 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 PC monitor via the HDMI port. Connect the DVI-HDMI adapter cable in the following order. First you must turn off both devices. Then, through a video cable, the TV is connected to a personal computer. The end of the cord with a plug is connected to the output of the PC (or laptop), and the other to the TV. After that, the TV is switched on first. Its operation is determined by an easy flashing of the screen, showing the loading of Windows from the computer being turned on. The video cable can also be combined with the old DVI digital video format interfaces. To do this, use a DVI-HDMI adapter. However, it is worth paying attention to one point: such a connection will not have an audio signal, since the DVI-format does not support the transmission of sound.

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 the technology of four-layer screening. It excludes the possibility of influencing the transmitted signals of electromagnetic and magnetic interference. The 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 the resolution of the picture 1920x1080 (1080 p).

HDMI-DVI adapter

Such a device has overall dimensions of no more than a standard matchbox. It is the following design: an HDMI connector and a DVI socket. When buying a DVI-HDMI adapter, you must first determine which cable will be used to connect the digital devices. And already proceeding from this information it is necessary to choose an adapter. To transmit audio signals, you can use a separate cable (if you have an audio or video receiver, you are advised to give priority to the digital connection). The main advantage of such an adapter is the absence of loss of quality in the transmitted image. This is very convenient for owners of Full HD or HD Ready TVs, as to view high-definition video, you do not need to purchase an additional Blu-ray player or media center. 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 the TV screen in perfect quality.
