What Is An HDMI Cable and Attention problems

When it comes to digital cables, HDMI Cables wholesale are the most advanced cables you can get today. HDMI cables transmit both uncompressed audio and digital video signals from one device (such as a Blu-ray player) to your flat-panel TV. This ability to carry both audio and digital video signals is great because it eliminates the need for separate audio and video cables, thus reducing clutter. What’s more, you get the highest quality signal possible because HDMI cables support all high definition TV (HDTV) resolutions (including 720p, 1080i and 1080p) as well as EDTV (480p) and standard definition signals. As for audio, while even more improvements are in the works, HDMI cables currently support up to 8 channels of 24-bit audio. This is the best you can get today.
HDMI 1.4 Specification
The HDMI 1.4 specification, which was announced in June of 2009, introduced some major enhancements to HDMI cables. These improvements were further advanced in March of 2010 with the release of the 1.4a specification. The most important capabilities included in the HDMI 1.4 specification were:
Support for Ethernet – This allows you to use an IP-enabled device without needing a separate Ethernet cable.
Audio Return Channel – This eliminates the need for a separate audio cable because you are now able to send audio to a surround sound audio system through the HDMI cable.
Support for 3D – the new version now support both input and output protocols for major 3D video formats. This allows you to get the full benefit of a 3D TV or gaming system.
Video Resolution Support Beyond 1080p – you now have full support for next-generation displays with super-high resolutions that are even higher than 1080p HDMI Cables.
There are several other enhancements introduced in the 1.4a specification. If you would like to learn more, read our comprehensive review of the 1.4a specification in our blog post entitled, What’s New With The Version 1.4a HDMI Specification.
The CL2 and CL3 Designations
The CL2 and CL3 designation define how HDMI cables react in a fire. Both CL2 and CL3 rated cables are made with flame retardant, low-smoke materials, making them safer if they are exposed to heat or fire. Because CL2 and CL3 cables are flame retardant, they can be used for in-wall installations. That means that these types of cables are safe to run through your walls. Never run any type of cable through your walls if they are not rated for in-wall use.
