HDMI Cable
Hi,
I have bought a few HDMI cables, but I just found out that there is different specification for them , and I would like to know how do I find out whether the cable are 1.3 or ealier -- Thank You in Advance Merci a l'avance Martin |

Most all cables sold lately are "1.3" cables. Nice summary at http://en.wikipedia.org/wiki/HDMI#Versions |

HDMI Cable
I still don't know how to identify whether my cables are 1.3 or not, I read
the whole page on Wikipedia (I can not say that I undertood everything, but I did most) "UCLAN" wrote in message ...

If you *must* know, check the retail packaging the cables came in, or the online site at which they were purchased. If none of the above works, and you can't sleep at night without knowing, buy new cables. Good HDMI cable FAQ at http://www.hdmi.org/learningcenter/kb.aspx#46 |

HDMI Cable
It is not that I can not sleep at night, it is somehow PVR and DVD, are made
to use 1.3 cable, and since I change my flat screen TV there is not signal that goes from either of them when they are using HDMI So I want to know if it is the cable or not before I buy new one, at over $30/cable, I do not want to throw them away for nothing "UCLAN" wrote in message ...

It is because of a bad cable, or incorrect implentation on your part. For less than 3-5 meter runs, v1.3 cables are not mandatory. What you haven't told us is the history of these cables. From the FAQ: "Q. Can HDMI cables contribute to devices not working properly together?" "The vast majority of image quality or interoperability issues with HDMI devices are related to the software (firmware) used for device communication and content protection, and have nothing to do with the HDMI cable. In particular, these issues are often caused by the software related to HDCP handshaking, or from devices improperly handling the device capability information read through HDMI (e.g. the device has an incorrect EDID, or an inability to properly read an EDID). It is fairly uncommon for the cable to be the cause of HDMI compatibility problems. In fact, the robustness of the HDMI specification has been verified by the fact that we have not found a compliant HDMI cable that is the root cause of HDMI playback issues with compliant devices." "Q. What is the difference between a “Standard” HDMI cable and a “High-Speed” HDMI cable?" "Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables. * Standard (or “category 1”) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal. * High Speed (or “category 2”) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600). "Q. Will my Standard cable work in High Speed applications?" Although a Standard HDMI cable may not have been tested to support the higher bandwidth requirements of cables rated to support high speeds, existing cables, especially ones of shorter lengths (i.e., less than 2 meters), will generally perform adequately in higher speed situations. The quality of the HDMI receiver chip (in the TV, for example) has a large effect on the ability to cleanly recover and display the HDMI signal. A significant majority, perhaps all, of the HDMI TVs and projectors that support 1080p on the HDMI inputs are designed with quality receiver chips that may cleanly recover the 1080p HDMI signal using a Standard-rated HDMI cable. These receiver chips use technology called “cable equalization” in order to counter the signal reduction (attenuation) caused by a cable. We have seen successful demonstrations of 1080p signal runs on a 50 ft. cable, and a 720p signal run on a 75 ft. cable. However, the only way to guarantee that your cable will perform at higher speeds is to purchase a cable that has been tested at the higher speeds and labeled as “High-Speed.” More good stuff in the FAQs.
