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 George Robinson

Great product and works perfectly. I had a 40ft ceiling for HDMI, had no issues with HD but the signal dropped when I upgraded to 4K. I already had CAT 6 mileage. Unit comes with wall brackets and two 4K compatible HDMI cables. Installation took 15 minutes. Only hiccup trying to figure out the EXT vs LOC dip switch. I still do not understand. At first there was no picture, I read the instructions 4 times and didn't understand. Then flipped the switch, waited 30-60 seconds and got the picture. I didn't have to manually set up my TV or 4K player to force 4K. He switched automatically. The device works flawlessly with no glare or cut outs on the first two movies I watched. In addition, it also has an IR return channel. I'm not using this yet but will be using Logitech Harmony to control my TV.
