When HDMI became available into the market there were a few individuals who compared it to DVI. The issue is, are they truly different or just the same? To learn more about this continue reading and figure out what’s in it between the two.

Before, it was DVI that rule the industry. DVI is Digital Video Interface after that HDMI arrived or the High-Definition Multimedia Interface. From the term alone you already have the concept that both are digital. HDMI and DVI have lots in common as well as have a couple of differences.

To begin with, HDMI has the capability to transfer both audio and video signals whilst DVI can only have video signals. This can be very convenient since you just require one cable for your video and audio signal transmission. Because DVI needs another wire for audio signal transmission HDMI wins in this factor. With HDMI you will not have jumbled wire connections.

HDMI is the newest in the digital technology field, and just like the DVI, it also has excellent-quality pictures and videos. High-speed HDMI cables cater 3840?2160 as well as 4096?2160 resolutions, whereas DVI gives up to the maximum of 2560?1600. Both HDMI and DVI produce the same quality of video, which is much better than analog by the way. Digital cables send out signals in binary (1s and 0s)-it’s either you obtain a signal or you don’t-nothing in between.

Another benefit of HDMI over DVI is its security feature. HDMI bears a content security protection called High Definition Content Protection or just HDCP. This HDCP operates by encrypting digital signals through an authentication key and in case the authentication failed then there will be no signal transmission. This renders your data secured because no one can simply transfer signals without the authentication key.

The physical aspect of the two is also very different from one another. HDMI again is ahead than DVI in this aspect. HDMI appears very much like an USB cable which is sleek and simpler to connect while DVI is large with a number of pins at one end. Now, HDMI definitely is more user-friendly compared to DVI but they have one thing in common, though they can be used to have long runs like wall installations you must get the kind of HDMI and DVI which are thicker so it can effectively send out signal without signal loss.

In case you would rather use HDMI, you might be glad to know that it is backward compatible, which means that you can hook up a DVI source to an HDMI output. What you need to seek out is a cable with a DVI connector at one end and HDMI on the other. This will enable you to connect DVI and HDMI devices without the need for external converters.

HDMI has the advantage over DVI when it comes to providing uncompressed audio and video altogether using just one cable. Although both DVI and HDMI are the same and the quality of video they deliver is not at all different, HDMI remains one step higher. With its increased bandwidth, HDMI can support future technologies, so you don’t have to think about buying a new cable when a new technology arrives.

HDMI has been around in industry for several years and today we can see several products that come with HDMI. Since it is commonly used, HDMI cable is provided now in numerous size and one of it is the 1.5m HDMI cable. To know the many lengths of HDMI cable, do browse 1.5m HDMI cable site.
