In the last 12 months sales of high definition televisions have skyrocketed. Today's cutting-edge Hdtvs and high definition sources demand dramatically higher data rate transfers than old generations of Audio / Video components. They place imaginable bandwidth/performance demands on Hdmi cables. In fact, today's most industrialized components operate very close to the limits of current Hdmi technology.
Online forums have been inundated with questions about Hdmi cables. As an manufactures insider I have been answering a amount of these questions. Here are five of the most often asked.

1. Is there literally a unlikeness between high-priced Hdmi cable and reasonable cable?
There is a unlikeness between high-priced and budget Hdmi cables. It revolves around the potential of the cable build and the materials used. The demand is either this will sway my set up. First you should conclude the distance between your source and your display. If this is less than 15 feet a "standard" cable will be ok.
If it is more than 15 feet you are best to think a "high speed" cable. Make sure that you buy from a reputable source and that the cable is marked with the Hdmi logo and says that it is a version 1.3 (don't worry about a, b or c as these are only testing protocols) If you live in a coastal or high humidity area it is worth considering getting a cable with gold connectors. While this will not improve your signal it will stop corrosion degrading the signal over time.
Some people assume that as the signals are digital either the cable works or not. Sometimes any way the 1s and 0s aren't all there because of signal degradation due to inferior cable construction. That can be especially true with audio and video sources such as Cds and Dvds. The signal will degrade gracefully, to a point and then it will break up. Music and video is not like data. Digital signal processors can work with a degraded signal and deliver less than perfect sound and pictures.
You can never improve a digital signal by using an high-priced cable but you can literally degrade a signal using an inferior cable.
2. Is it ok to bend Hdmi cables?
It is best to avoid bending an Hdmi cable, literally do not kink it. What this does is changes the distance between wires, shielding and insulation internally within the cable.
The process of cable found can have a dramatic result on how the transmitted facts looks from one side of the cable to the other. This means that a cable with great shielding and a more accurate distance between the "intelligence" and "ground" wires, will yield a great relationship with less interference. Many things can sway your signal. The electrons will originate a standing wave in the cable; this will originate a small magnetic field around the cable. Any imperfection or splice in the cable will disrupt these waves and will reflect/refract the waves. Magnetic facts can also leak from one cable to another.
3. Should I buy 1.3a Hdmi Cables or 1.3b Hdmi Cables or what?
There is a bit of blurring in the shop about all of the versions. What you are referring to here is the specification version, not to be confused with the connector type.
As long as you pick version 1.3 you will be ok. The suffixes of a, b or c merely refer to the testing protocols and literally have no buyer impact, although makers are using them to market. (bigger numbers/letters are better...)
4. Will I be able to get the same potential video/audio with a Hdmi to Dvi-D cable?
"Dvi-I" stands for "Dvi-Integrated" and supports both digital and analog transfers, so it works with both digital and analog optic Display Units. "Dvi-D" stands for "Dvi-Digital" and supports digital transfers only. Dvi also includes provision for a second data link for high resolution displays, though many devices do not implement this. In those that do, the connector is sometimes referred to as Dvi-Dl (dual link).
When you change Hdmi to Dvi you drop the audio as Dvi does not sustain any audio signals. You will need to take a separate cable link between your source and the sound ideas for this to work.
You will need also to relate the software settings in your source so that they know that you are not outputting audio from the Hdmi but a separate outlet.
Some new Dvd players, Tv sets (including Hdtv sets) and video projectors have Dvi/Hdcp connectors; these are physically the same as Dvi connectors but transmit an encrypted signal using the Hdcp protocol for copy protection. Computers with Dvi video connectors can use many Dvi-equipped Hdtv sets as a display; however, due to Digital possession Management, it is not clear either such systems will at last be able to play protected content, as the link is not encrypted.
5. When I connect my laptop Blu-ray to my Hdtv I get an error about violating copy rights. What can I do?
You are facing an Hdcp (High def copy protection) issue here.
Hdcp is a form of digital copy protection industrialized by Intel Corporation to prevent copying of digital audio and video article as it travels over assorted cables and connections, even if such copying would be permitted by fair use laws. Each device handshakes with the other and then passes an encryption key to say that it is ok to display or play the signal. It does this for every frame, typically 30 times per second. If you are having problems with blank audio or video it is more than likely that one of your devices does not sustain Hdcp.
Typically if you are connecting with Hdmi all the way through the relationship chain you should not have this problem.
