HDMI Field Bulletin Because HDMI is the hot new thing, we get a lot of questions about it. And because the connectors (mandated by licensing agreements) on both the cables and on the equipment are more fragile than most they are easy to damage. Here are some tips, and additional information that we thought you may find helpful: o
All AudioQuest HDMI cable models are certified and fully HDMI compliant. That’s our starting point. In addition, we use larger conductors than the norm and silver plating for improved performance.
o
Our better HMDI cables really shine on longer lengths. It’s expensive to preserve the integrity of delicate digital video signals over long lengths.
o
We make HDMI and DVI cables in long lengths. However, because the sending and receiving circuits are different in different products, we always recommend testing all components in the chain (the source, receiver or processor, cables, and display) to ensure they function properly together. This is especially important when the cables are to be run in the walls or ceilings and when the cables are 12 m or longer.
o
No HDMI cable over 7.5m long can support a signal and deliver full 1080p performance.
o
In order to be able to run longer lengths, within 60 days we plan to introduce an HDMI Extender that effectively doubles the usable distance. It is about half the size of a cigarette pack, receives power from the HDMI source piece, and is to be installed in-line, between two cables. Stay tuned for more info as we near the introduction date for this product.
o
Our new, inexpensive HDMI-A cables (all copper, not silver plated as stated incorrectly in the March 2005 Retail price Book) and HDMI-X are now also available in HDMI > DVI as well as HDMI>HDMI configuration. Please specify when ordering.
o
Always strain relief HDMI cables whenever possible. This can be as simple as wire-tying to another cable. It lessens the chance of damaging the connectors. Or having them fall or be pulled out.
o
Our DVI>HDMI, HDMI>DVI adaptors, swivel adaptor, and couplers do not hinder performance. Use them with confidence – but again, strain relief the cables (see above).
o
We have heard of a number of problems involving the new HDMI switching A/V Receivers including those from Denon and Yamaha. Many have problems when they are switching HDMI sources, particularly cable boxes. You may want to test this switching capability before committing to a particular system design, and running cables. The receiver manufacturers want to be sure you are using fully compliant cables. With AQ – you can be confident that you are (see first item on this list).
o
Component video is a stable and reliable way to handle a Hi-Def video signal. It is always smart to include a long component video run in parallel with an HDMI cable, when access to those cables will be limited in the future. The MAC-3 and MAC-6+ cables are perfect for this.
o
When using the best available component video cables, some people prefer the results to those achieved with DVI or HDMI. Don’t rule out component video as a viable alternative simply because it isn’t the newest.
o
The highest settings do not always produce the best results. Don’t automatically assume that because your display can handle 1080i you should set your DVD player to output 1080i. A lower setting may produce fewer artifacts, and a better picture. For a good explanation of why, see the article “HDMI me” by Thomas Norton in November 8, 2005 Ultimate AV Newsletter.
