The monitor is connected to other devices using various interfaces, which are currently abundant. Depending on the technological solution, the connection options are of two types - analog and digital. The latter are represented by two main interfaces - DVI D or HDMI. What is better and what, in fact, is the difference between these technologies? Which connector should you choose? The following will be discussed in more detail, the better HDMI than DVI.
The requirements of modern technology
To determine which connector is better - DVI or HDMI, you should understand why you need to consider only these two connectors, because there are other interfaces, for example, DisplayPort or VGA. Firstly, DisplayPort is used primarily to connect the monitor to a computer, providing a connection between multiple screens, but for the HD format this interface is definitely not suitable. VGA is considered to be an outdated solution at the moment, many leading companies have refused to use it in their technology. By the way, it was thanks to VGA that the analog signal was transmitted .
But analogue broadcasting today also recedes into the background due to the fact that it clearly shows the majority of imperfections in the image. The device first converts the digital signal to analog, and then vice versa. Excessive transformations of the picture leads to noise appearing on the screen - bifurcation, copies of objects, buttons or text become a frequent problem. Particularly vividly, these shortcomings are noticeable on the first modern LCD monitors, which only supported VGA connection.
As for the connectors, now most manufacturers place ports for both digital cables on the rear panels of the equipment. But, as a rule, this only complicates the task when you need to decide which cable is better - HDMI or DVI.
Interface Common Features
Both HDMI and DVI transmit video using the same technology called TMDS. The necessary information in this case is encoded in such a way as to obtain the most harmonious sequence of bits. Thanks to the latter, a high level of frequencies is achieved and, as a result, a better image.
In addition, only one cable is used for one port and the other (despite the fact that HDMI is single-channel, but DVI is a multi-channel solution, which will be discussed below). This is possible thanks to the use of special adapters.
Distinctive features
Many personal computer users opt for High-Definition Multimedia Interface. Why is this - the better HDMI? What can DVI not boast of? There are two main differences:
- An HDMI cable can transmit not only video but also audio. This provides high quality not only sound but also pictures. Most DVI models do not have such a function, although, of course, there are exceptions to the rules.
- High-Definition Multimedia Interface is a single-channel cord, but the data transfer rate reaches one hundred megabits per second. But the products of a competitor are distinguished by several channels, one of which transmits an analog signal. For devices powered by such a signal, a DVI cable is just a godsend. Thus, the company keeps up to date, but does not ignore the needs of owners of equipment, which can not boast of an innovative "filling".
To determine what is better than HDMI than DVI, you need to understand that the image quality is more dependent on the device that needs to be connected. The picture that appears on the screen is affected by the signal level. But the stability and quality of image transmission is already provided by the cable.
But do not try to connect one cord in place of another, for this there are special adapters. Otherwise, you can simply lose the sound. Although both interfaces work using the same technology, the differences make themselves felt.
High-Definition Multimedia Interface
What is better than HDMI than DVI is that it is the High-Definition Multimedia Interface that is used by many companies that produce equipment. It is such a common interface that with hdmi you can connect not only televisions and monitors to computers, but also laptops, tablets and smartphones, game consoles and players.
The cable, consisting of only one channel, is still widescreen, allowing you to form an entire system from various multimedia devices. The latter in some cases is especially necessary.
New cable versions have excellent compatibility and can easily replace previous models. HDMI has good bandwidth, which is important for gamers or just those users who like high speeds and superior sound. At the same time, HDMI is completely innovative, supports only digital format. That is, any old models of equipment cannot be connected using it.
Digital visual interface
DVI-interface has three varieties that support various modes - digital, analog and analog-digital. A picture with a high expansion, this cable can transmit a distance of not more than five meters. Signal transmission can be carried out in two modes. The first is single link (single mode), the second is dual link (dual mode). The latter provides operation at high frequencies. So, with a poor-quality picture when using the single mode, it is dual link that will correct the situation.
Competitive advantage
HDMI is a more intelligent interface anyway. Developers monitor trends and keep up with the times. Most models of modern technology at the moment and in the near future will definitely use this particular type of cable.
HDMI or DVI for the computer, which is better to choose? In this case, you can use one or the other interface. The final choice depends on the destination. If high-quality sound is important, then it is better to use the first connector, in the absence of this need, DVI is also suitable for connection. This type of interface is especially good because its developers, although they are developing technologies, do not forget about those who use old devices. After all, quite a lot of users have computers and televisions that are already "not in trend." It is in this case that it is better to dwell on DVI.
