Unfortunately this does not work with multiple HDMI sources on multiple HDMI displays. I've tried category 6 cables and 2 different category 5e cables, all shorter than 100 feet. All 3 cables worked, I can connect them to other devices. This product took longer than expected to ship, which stunned me when it arrived and was not working. I ended up having to create a workaround for my event that wasn't optimal. If it worked it would be a very good solution for me. I don't know if this is due to compatibility with my devices or just a faulty device, but I ended up having to buy a much more expensive version of this solution locally. Unfortunately we don't have a micro center nearby or anything else with good prices and we ended up paying nearly 4x for a working alternative product.
