High-Definition Multimedia Interface or HDMI is an industry-supported AV interface. It has been brought into use to transmit uncompressed digital data. It has turned out to be a great alternative for analog standards, because they have both video and audio interface combined in a single cord instead of the multiple cords that used to be in circulation earlier. These are among the best cables available for personal computers, Blu-ray disc players, DVD players, video projectors, televisions, and video game consoles. These cables have several advantages over the other forms of interfaces, which are discussed below.
One of the first and most important advantages of HDMI cables is that they transfer uncompressed digital audio and video with the highest quality. If you want to get the best resolution, you may choose Category 2 HDMI cables. These are also known as high-speed cables. These have been tested at 340 MHz. Besides, they offer resolutions like 1080p60 and 2160p30. In fact, this is much better than the Category 1 cables, which only offer 720p60 and 1080i60 resolutions.
One of the special features of the HDMI cables is that they have backward compatibility. This means they can be connected to the earlier interface such as the DVI as well. The only requirement is that you connect the DVI with HDMI. No other interface enables this type of connection.
HDMI cables are very cost effective when you consider the quality of the picture they deliver. Besides, they are also very easily operated and can be availed at as low as $25 for 1080p resolution. The cables that support HDMI 1.3 and belong to Category 2 cables are the most affordable ones. They also support uncompressed video formats from the cable TV providers in my area. The prices vary according to the length of the cable you require. Still, they are very low-priced when compared to analogous cables.
One of the best thing about HDMI cables is that there is no more clutter behind your devices caused by a bunch of wires. These have been replaced by a single cable from the respective cable providers. It serves the purpose of multiple wires that were used to transfer audio and video separately.
HDMI cable directly renders digital interface, unlike the analog interfaces. The latter requires a digital-to-analog and vice-versa to be transmitted. This causes the degradation of signals. However, the signal quality is unchanged in HDMI cables all the way.
