If there is any question about household appliances, we go with a piece of paper to the nearest store and try to get the answers we need. So I, one day, ask a sales assistant: “What is the difference between HDMI and DVI?”, He answers without hesitation: “It's just that DVI is outdated, today few people use such cables, but HDMI is already a new generation!”.
I saw perfectly well that a large number of computers are still equipped with DVI outputs, but HDMI is also found more and more often.
In fact, the difference between the two interfaces is obvious.
If you decipher the abbreviation, then everything will fall into place. In short, HDMI (High-Definition Multimedia Interface) transmits video signal and sound simultaneously, while DVI (Digital Visual Interface) transmits only video. As for the quality of the picture, there is really no difference, here the screen on which the image is displayed is already playing an important role.
HDMI is much more compact, this interface does not need special mounts, which is why it is also used in mobile electronics. But DVI is much larger, and it was not without mounts.
There is still a difference
HDMI bandwidth is three times that of DVI. In terms of numbers, this is up to 10.2 Gbps versus 3.4 Gbps for DVI. In addition, a standard HDMI cable can easily reach 15 meters in length, while for DVI, here you can only use cable lengths up to 10 meters.
There are two versions of HDMI cables
There are two versions of HDMI cables - 1.3 and 1.4, so to speak, old and new. HDMI 1.4 is a later, evolutionary version. Supports ultra-high definition video 2K and 4K, but HDMI 1.3 only supports FullHD resolution. And also version 1.4 can work with the 3D image format. There is a nuance ... To ensure a greater level of device compatibility via an HDMI cable, for example, if you are going to watch movies from Blu-ray discs in 3D 1080p, also play games in Full HD, watch TV in Side-by-Side 1080i modes or Top-and-Bottom 720p, then an even more advanced HDMI cable marked 1.4a is required.
Digging deeper, it turns out that there are several types of HDMI connectors that vary in size. In cases where portable devices are used, be it a smartphone, tablet or even a photo-video camera, then HDMI connectors of a reduced format with a mini or micro prefix are used.
In fact, the topic of the difference between HDMI and DVI is not at all complicated, the minimal knowledge outlined in our material is enough to understand the nuances and make the right choice. Then the purchase will be really successful!
