C2G Address HDMI Extension Challenges and Solutions in New White Paper

Joe Cornwall’s “Ghost in the HDMI Machine” White Paper Offers Insight Into the Payload Factors Contributing to HDMI Extension Issues

DAYTON, Ohio — March 9, 2022 — C2G is providing AV integrators with an in-depth look at the challenges of extending HDMI connectivity beyond its 15-meter passive connectivity limitation in its latest white paper “Ghost in the HDMI Machine,” written by Legrand’s AV Technology Evangelist Joseph D. Cornwall, CTS-D/I. Available for download here, the white paper dives into why this high-bandwidth connection is sensitive to a number of issues arising from manufacturing decisions and installation environmental conditions and how integrators can ensure dependable operation of client’s media solutions.

“HDMI is both the single most significant connection — and challenge — of 21st century AV design,” said Cornwall. “While we’ve certainly come a long way since the inception of this technology, there are still times when a well-done installation mysteriously runs aground. At that moment, it’s often difficult to pinpoint the source of the problem. That may lead to some intensive hours spent troubleshooting and ordering equipment. This white paper is the result of our intensive research and analysis and exposes what lies at the heart of many HDMI extension problems — proper application of power. Our goal is to help integrators anticipate, avoid, and address HDMI issues efficiently and effectively.”

Key information highlighted in the white paper includes:

Illuminating the potential and reasons for HDMI failure because of voltage starvation
The role that the I2C HDMI transport protocol, chip sets of active copper and active optical cables, and more play in payload complexities
A power supply analysis of tested sources
Solutions for mitigating HDMI extension link issues today

About C2G
When you need reliable connections, be sure to turn to C2G and our high-performance cabling and connectivity solutions. We’ve grown into respectable players in the IT and AV industries, though we still retain our scrappy vibe from the early days. And we’re not above having the occasional mascot. (We miss you, Cable Guy and Captain Connector!)

That’s what you get with C2G – an incredible focus on delivering unique, value-added solutions along with a singular commitment to creating lasting, dependable partnerships. It’s not unheard of for executives to be seen repackaging products in shipping or for a sales rep to hand deliver a rush order when unusual circumstances arise. We’ve been that way since our founders ditched their 1984 Salem Mall PC resell store in Ohio to focus on expanding the custom cables they made in the back that were selling like hotcakes.

We use premium components and the latest technologies to keep pace with the fast-moving changes in AV technology. Quality is so important to us; we have our own manufacturing plant to ensure our products meet our demanding expectations. We put our cable performance second to none and make sure we comply with industry specifications across RoHS, R.E.A.C.H. and WEEE. Check out our 7,000+ stocked solutions or ask about custom kits.
