There is a countless number of TV, DVD, Blu-ray players and other electronic equipment and each one of them with their own goals and agendas, trying to push this or that technology. The complete standardization of the TV and PC video and audio formats is definitely still in the future and the consumer is left with countless choices and no direction. When it comes to setting up a home theater, you can choose to connect your equipment with DVI, HDMI, Component Video and many other cable types and even if you know what each one of them does and does not, picking the best one is still challenging. The truth is that all these interfaces have their advantages and weaknesses and for different setups, a different one might be appropriate. For instance, many people believe that they should not use Component Video since it is analog, but the analog canals are capable of transmitting a signal over much longer distance than a digital HDMI cable.
However, most people would heartily recommend HDMI cables for your home theater, and in most cases, they would be right. The HDMI cables carry digital signal, which does not require conversion and carry audio and video over a single cable, which would make your setup much neater. In addition, the latest version HDMI supports 4K × 2K resolution, which is actually not supported by any hardware yet. This means that the HDMI interface is ready for devices that are going to be manufactured in the fixture and will support newer and more bandwidth-intensive TV and PC video formats. Another advantage of the HDMI cables over other types is the fact that they support the most widely used audio codecs and formats and could help you get the best surround sound from your audio system. The only drawback of the HDMI cables seems to be the relatively short distance that they work over, but for most users this is not an issue at all. When linking a video or audio source to a TV only five or six meters apart, the HDMI cables will give you excellent quality audio and video as long as both devices are HDMI-ready. However, if you want to connect a video source, which is more than ten meters away from your TV, then you might (or might not) run into problems. A single HDMI cable should work over 10 to 15 meters distance, but longer length might require extenders or the use of active HDMI cables.
