Before, analog wires were used to connect DVD or cd players and gaming consoles to televisions. The use of analog connections caused problems such as low quality videos, constant video interference and wire tangles. With the help of an hdmi cable today, people can now watch high quality videos and play video games with realistic graphics. The introduction of this type of cable in 2002 was not an instant hit to people. It took a while before televisions adapted to this technology. But today, most HDTV’s are built with hdmi ports. In fact, the best way for a television to display high quality videos is through this cable. Although this cable is useful in many ways, there are still some problems that people encounter with its use that every buyer should know.
Pros of Hdmi
•Ease-of-use – The main advantage of getting an hdmi cable is that it only comes in a single cable. This means that there is less wire clutter and people will no longer be confused to as where the cable should be connected. There is no need to use multiple cables because with hdmi, both the audio and video feeds use the same cable.
•100% digital performance – Older cables used to compress audio and video date before displaying them. Because of this, the quality of the video is reduced. On the other hand, hdmi no longer needs to do this. It uses uncompressed data and delivers pure digital video and audio feeds. Because of this, videos are crisper and are shown at higher resolutions.
•Auto-adjust – The system intelligence of hdmi capable devices can adjust the appropriate aspect ratio and resolution that would give people the best viewing experience. The source device and the television will communicate with each other and determine the best setting to be used. Without using hdmi cables, people will have to manually do this. For them to get the best output manually, they must know what resolution does their television has and what resolution does the video come in before they manually adjust the settings.
Cons of Hdmi
•Display abnormalities – Display abnormalities such as screen blackouts and flickering can be experienced when using hdmi cables. This is usually caused by the authentication process hdmi uses to prevent unwanted access. This authentication process, also called as handshake, is supposedly to take place in an instant. However, this is not the case for many users. Usually, this process takes place at a slower pace than expected. This causes the delay and other abnormalities people experience with hdmi. The problem becomes even worse or more frequent when this type of cable is used on cable boxes.
•Cable length – Other cables can run up to any length and still function properly. With hdmi cables, cable length is only limited to 35 meters for standard types while the high speed variation can only go for as long as 10 meters. Going beyond this distance will require the use of extenders such as UTP, fiber and coaxial.
Although there are some cons when using an hdmi cable, a lot of people still use this cable for HD outputs because of its performance. In fact, most manufacturers include hdmi ports on their laptops and monitors as one of their standard features. Because of this, the use of hdmi cables is one of the most practical ways to watch high quality videos. Even gaming consoles recommend the use of hdmi cables to view the best graphics their games have to offer. If an hdmi cable is not used, the quality of a video will only be mediocre even if the best HDTV’s and blue ray discs are used.
