Luxi CHD-110 HDMI communicator for fixing HDMI's EDID and HDCP problems

The Luxi CHD-110 HDMI Communicator is the world’s first solution for HDMI EDID and HDCP issues. It helps resolve most problems related to EDID negotiation and HDCP content protection. This device works using a female-to-male pigtail, eliminating the need for separate mounting. It’s an essential tool for AV installers.

Why you need it:

• About 15% of all HDMI systems fail due to the communication (handshaking or copyright) collisions even when nothing wrong with each component.
• This leads to the customers and installers frustrations; the reputation damages and unnecessary product returns to the manufacturers.

How does it work:

The root cause of most HDMI problems in the field is the I²C communication protocol used in the DDC line which carries both HDCP and EDID data. The I²C uses one wire for two way communications; when one device does not detect another device already talking on the line, it would start talking at the same time and causes collisions and lead to corrupted HDCP or EDID data. The Communicator has microchip inside to alter the communication timing to avoid collisions and issuing new HDCP key.

Troubleshoot first before using this product:

One of the most common and puzzling symptoms of any HDMI based system is that the display having a flashing or snowy picture or no picture at all, even the system is well designed and installed and each component is tested good. The two most likely causes of this problem are:

• 1) System does not have enough bandwidth or the cable is too long for the signal data rate.
• 2) DDC (hand shaking or copyright) communication breaks down.

How to fix the issue:

• First bring the source device next to the display and connect the two directly with a short (2m) HDMI cable to verify if the display is compatible with the source.
• Lower the source device output data rate (primarily the resolution) by one step (e.g., from 1080p to 1080i/720p, or from 1080i/720p to 480p), then reconnect the source device back to its original place in the system.
  • If the picture comes out, then you know the problem with the system before was caused by not enough bandwidth of the system.
    • Add a HDMI Extender between source and display or HDMI booster somewhere in series with the cabling to fix the problem.
  • If the picture still does not come out after lowering the resolution, then most likely it’s a DDC communication problem and use this HDMI Communicator to fix it.
