Recently, I was finalizing a large commercial audio video job and needed to test a connection from a laptop to a video projector. I needed the laptop to be located in the front of a large auditorium and the video projector is mounted 16 feet up on the ceiling. We are projecting an image over 200” diagonal. The laptop HDMI output was to run via HDMI extenders to an HDMI matrix switch input and then outputting from the matrix switch, through more extenders, to the video projector and seven plasma TVs. The other sources, DirecTV box, DVD, AppleTV, etc worked great to the projector and the plasma TVs. They were connected directly to the HDMI matrix switch inputs via an HDMI cable. When we tried to connect the laptop, via HDMI extenders, to the HDMI switch input, we had severe video dropouts. The video image would only come on for a few seconds and then go away for minutes. I swapped everything in an effort to isolate the problem. I tried several brands of HDMI extenders, including (5 brands), and not one would work consistently. I had installed CAT6 cable and there was no way to run a new wire now either. The next morning, I received an e-mail asking me to try out your Zigen extenders. I called Zigen tech support and explained to you about the problem I was having. You told me that your extenders will likely resolve my issue. I received the Zigen extenders, installed them the next day, and the video image was stable and perfect.
I can’t thank you enough for your help and for building a superior product. This problem was a major show-stopper for us, with no known solution. I am signing up as new Zigen dealer and will use your extenders exclusively. I called and ordered three more sets to quickly resolve some nagging issues at a couple of other jobs. A true Plug & Play product like this makes our job easier and helps us look professional when stuff works the first time.
Thank you, Dave
