5 of the Most Frequent HDMI Questions Answered

 

In the final 12 months sales of high definition televisions have skyrocketed. Right this moment's reducing-edge HDTVs and high definition sources demand dramatically higher data rate transfers than earlier generations of Audio / Video components. They place incredible bandwidth/performance calls for on HDMI cables. In truth, at the moment's most advanced components operate very near the limits of present HDMI technology.

 

 

Online boards have been inundated with questions about HDMI cables. As an business insider I have been answering a number of these questions. Listed below are 5 of the most usually asked.

 

 

1. Is there really a difference between expensive HDMI cable and cheap cable?

 

 

There is a difference between costly and funds HDMI cables. It revolves across the quality of the cable build and the materials used. The query is whether or not this will affect my set up. First you should determine the length between your source and your display. If this is less than 15 ft a "customary" cable will be OK.

 

 

If it is more than 15 ft you might be finest to consider a "high speed" cable. Make certain that you buy from a reputable source and that the cable is marked with the HDMI logo and says that it is a model 1.3 (don't worry about a, b or c as these are only testing protocols) If you happen to 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 because the signals are digital either the cable works or not. Generally nevertheless 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 equivalent to CDs and DVDs. The signal will degrade gracefully, to some extent after which it will break up. Music and video just isn't 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 expensive cable but you possibly can actually degrade a signal using an inferior cable.

 

 

2. Is it OK to bend HDMI cables?

 

 

It is best to avoid bending an HDMI cable, certainly do not kink it. What this does is changes the distance between wires, shielding and insulation internally within the cable.

 

 

The process of cable manufacture can have a dramatic impact on how the transmitted information looks from one side of the cable to the other. This implies that a cable with higher shielding and a more precise distance between the "intelligence" and "ground" wires, will yield a greater connection with less interference. Many things can have an effect on your signal. The electrons will create a standing wave within the cable; this will create a small magnetic discipline around the cable. Any imperfection or splice in the cable will disrupt these waves and will mirror/refract the waves. Magnetic information may leak from one cable to another.

 

 

3. Should I purchase 1.3a HDMI Cables or 1.3b HDMI Cables or what?

 

 

There is a bit of confusion within the market about the entire versions. What you might be referring to here is the specification version, not to be confused with the connector type.

 

So long as you select model 1.3 you will be OK. The suffixes of a, b or c merely consult with the testing protocols and really have no consumer impact, although makers are utilizing them to market. (bigger numbers/letters are better... )

 

 

4. Will I be able to get the same quality video/audio with a HDMI to DVI-D cable?

 

 

"DVI-I" stands for "DVI-Integrated" and helps both digital and analog transfers, so it works with each digital and analog Visual Display Units. "DVI-D" stands for "DVI-Digital" and helps digital transfers only. DVI additionally includes provision for a second data link for high resolution displays, though many units don't implement this. In those who do, the connector is typically referred to as DVI-DL (dual link).

 

 

While you convert HDMI to DVI you drop the audio as DVI doesn't help any audio signals. You will have to take a separate cable link between your source and the sound system for this to work.

 

 

You will want additionally to review the software settings in your supply in order that they know that you're 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 identical as DVI connectors but transmit an encrypted signal utilizing the HDCP protocol for copy protection. Computers with DVI video connectors can use many DVI-equipped HDTV sets as a display; nevertheless, as a result of Digital Rights Management, it is just not clear whether such systems will eventually be able to play protected content material, because the link will not be encrypted.

 

 

5. Once I join my laptop Blu-ray to my HDTV I get an error about violating copy rights. What can I do?

 

 

You are going through an HDCP (High def copy protection) issue here.

 

 

HDCP is a form of digital copy protection developed by Intel Corporation to stop copying of digital audio and video content as it travels across varied cables and connections, even when such copying would be permitted by honest use laws. Every gadget handshakes with the other after which passes an encryption key to say that it is OK to display or play the signal. It does this for each frame, typically 30 instances per second. If you are having problems with blank audio or video it is more than likely that certainly one of your devices does not support HDCP.
