5 out of 5 eggsUpdate

Pros: Greetings TechLords..

I found out what the problems/issues are concerning the use of these devices.

When hooking 2 or more of these units together, you need to use cable
HDMI cable that is in full 1 to 1 connectivity. That means, they can
fully pass a HDMI tester with all green lights on all channels/lines/wires/data lines etc.

I have only found a few hdmi cables that can do this.
Most cables are "chopped" and are missing 3 to 7 pins of data/signal.
Those cheap cables work fine going from computer to monitor, but this device
needs to have all the pins. I cannot believe Comprehensive Tech Support did not
tell me this in the chat session.

I tested cable after cable until I got stuff to work, and that verified what was going on.
I bet I tried 8 different cables from different manufacturers.

The cable I bought earlier in the year that had these properties, are now out of stock.
So I need to try some others.

I am not sure why the Cable Manufacturers will not disclose if there cables are "FULL" or not. If I get them and they are not "FULL", I send the stuff back and blast them on the reviews...
