HDMI Tools & Solutions


More and more consumer electronics products continue to emerge into the full HDMI™ digital environment. With these new HDMI™ products usability and reliability will be a challenge.

The popular belief that “digital is simply 1’s and 0’s and HDMI™ does not care about cable quality” is just not true!

The HDMI™ cable is the most sophisticated audio/video interface in the history of home electronics. And while some believe there to be litte need for higher quality cabling, testing has shown that quality counts. The internal geometry of an HDMI™ cable will determine how well and consistent the data between devices will travel. Proper two-­‐way communication is critical between HDMI™ sources and without it, problems can occur.

Since the inception of HDMI™, Ethereal has been leading the march for higher quality cables and problem solving solutions to help ensure more reliable connectivity via the HDMI™ platform.

Here at Ethereal we don’t “stretch the truth” or make claims that just aren’t true. Ethereal works directly with industry leaders and designers to design affordable, high quality and reliable home theater products. So when you need real answers to real problems look to Ethereal HDMI™ solutions to help get your picture back on the screen.
