Review on 🔌 Cable Matters 4K 60Hz HDMI Extender Balun with HDMI 2.0 and HDR - Wall Mount 4K HDMI Over Ethernet Extender up to 164 Feet - Supports Local Monitor Loop-Out: Optimal HDMI Extension Solution by Abdalla Galloway

Update 4/30/21: After a few months everything was working fine. During the winter I had occasional failures with our heat pump, but once I switched back to the air conditioning the failures became fairly frequent. I had a keystone and connector that had to be unplugged and after that it now works in place. I turned on the AC and turned on some other elements at the same time. No falls. So the key is to use a piece of wire. No connections, no sockets. In fact, it's just a very long connecting cable. Update 12/30/20: So after a few weeks with a new wiring configuration I've come to this conclusion. This device works perfectly/amazing/best when using a non-disruptive cable. For some reason the reliability of the signal drops rapidly every time you add a coupler or capstone. My final iteration is that I removed all the keystones, connectors and patch cords from the setup and had to connect the cables as below so it's a continuous run. All stability issues have been fixed. If there was one trapezoid left in the mix it worked 99% of the time but when my AC kicked in. the signal disappeared and returned within 2-3 seconds. and when exiting the loop. Perfection! So, to the credit of Cable Matters, my request isn't going anywhere. They took the time to not only answer it, but ran some of their own tests just to prove that it matches my tests. At least I have a second TV that works great and has the same sound and picture performance as if it were connected directly to a cable box. everything worked fine. Then I bought a new TV and there is still no explanation as to why I had any signal dropping issues in the first place. I contacted Cable Matters and they responded. Typical basic response to an initial email asking questions about my hardware and setup. I didn't expect more but I received MUCH MORE information than I ever expected and we emailed each other several times in a consistently positive manner. It's huge in my book. The real person on the other end who actually reads the email and can understand what I was trying to say. They even went as far as testing the device on their site and that's how we came up with the solution. THAT is customer service. Being able to provide limited technical information about the signal quality as I don't have the equipment to address it, they picked up what I said and responded with what I could try - again unexpected and awesome to do. I know it's a one-way street too. They'll learn something they didn't know, and maybe it's something that can be overcome in a future product, or it could be an overhaul of the instructions that will help someone else. Now that I know that, I would never have a problem starting with it. It seems like every time I have a connection the signal between transmitter and receiver gets degraded. It was even determined where a short cable is and where a long cable is, if you connect several together, it does/does not work. To put it mildly, very interesting. My build is in a wall so I had keystones at each end and a data center in my basement where I connected two cables with a coupler. That means I had two patch cords (one at each end) and two wires in the wall that connected to a port in the basement --- 4 wires total - so it's easiest to imagine the total length being less than 100 Foot. I've since spliced the crimp connectors I had left over from the wired alarm, made two connections in the basement, and finally ran the wire from the wall to the transmitter, effectively reducing the setup to a patch cord and a keystone wire to the wall. on one end and a plug on the other. What does it all mean? To put it simply, if I had it and could do it all over again, I would run a straight through cable from where I have the transmitter and receiver and let it extend 6 feet out of the wall on both ends, with connectors on each end – actually a connecting cable from the transmitter to the receiver. Up until this point, as a temporary setup, I was running standard 50ft Cat5e cable across the floor left over from something else, which was working great while I tinkered with my in-wall setup. So right now I have a stable melody. If I still have problems with the signal, I unplug the connection cable and do the same thing as on the transmitter side, unplug the keystone and just run the cable away from the wall. But up to this point, with the keystones removed and the cables spliced (I confess I'm NOT a fan of this, but in this case I don't have much choice/possibility) everything works as it should. I can definitely recommend Cable Matters. I use their cable at home and at work and I think there is up to 30,000 feet between them. I also use their other products and if they support that kind of customer service. All I can say is that I will remain a customer for life. First Review: What helped me was the fact that the host (sending unit) has a built in HDMI splitter. The picture quality is the same as if my FIOS device was connected directly to the TV. I connect it with CAT6 cable, just like my previous installation elsewhere with two other brands. I only had CAT5 --- and that was the problem. For any good network cable installation for any reason --- I will only use solid copper or stranded copper depending on what it is intended for. I will not use copper clad aluminum. He's just not that good. In the end, the box works as it should and is a welcome addition to my electronics menagerie in my smartphone.
