Review on HDMI Extender Over Ethernet 4K 60Hz Uncompressed 444 - Cat5e Cat6 Up to 40m(165ft)/ 70m (230ft), with CEC, RS232, POE, IR, HDCP2.2 and EDID Switch by Kenyatae Tillo

Replaced a unit that ran from my home theater to a waterproof backyard unit. This way I can move the projector from the theater to the backyard. My total mileage is about 140ft, which translates to 128ft of Cat5e (replaced with Cat6) and 6ft of HDMI 2.0 at each end. That mileage is long enough to be able to project from behind without people tripping over cables and getting in the way of the projector. My last device cost a fraction of that and basically did the same thing. The main reason I wanted to upgrade was the Poe. I have limited power where I'm projecting so there's one less outlet which makes the process easier. PoE works, although after a night at the movies I have to remember to go to the movies and turn off the transmitter or both devices will stay on. whether there is a signal or not (and they get very hot). A great feature would be a switch on both devices that controls both devices. Even better would be to use a sleep timer when there is no input that disables both the TX module and the RX module. Anyway, I've changed the socket that the theater device is plugged into to a Zwave socket, which allows me to turn both devices on and off with the Hubitat. I haven't used RS232 but am assuming it controls devices through the boxes, not the boxes themselves. Try an IR repeater. It's a great idea, but it's not needed in my scenario. I originally used terrestrial ethernet as Cat5e which worked in 3D, 5.1, with CEC on my previous HDMI extension system. This one worked almost as well, but dropped CEC commands and audio quality, and the timing was variable. The work light on the RX module was blinking menacingly, which the manual explains means the unit is not receiving a full signal. Luckily I ran the outdoor ethernet in conduit so it was easy to switch to Cat6. I ended up needing another Cat5e cable somewhere else in the backyard anyway, so it worked. With Cat6 I get 3D 1080P, CEC and TrueHD. Not bad. but he still has an ominous flare. I didn't notice any quality degradation with the new cable, so it will only blink, I don't care. I would look into optical HDMI before investing in Cat7, but the flickering could just mean I can't run 4k HDR. I won't be moving to a native 4k projector for a while, so this isn't a deal breaker. For what it's worth I used Cat6 with no internal separator so it could be a crosstalk issue. My components are connected through my receiver on the TX side and I get PCM audio through each of my 5 external speakers (and 3 other channels that my receiver can drive but isn't connected). CEC is very convenient for volume control and works well. I usually use my Apple TV on an external display (connected internally to the receiver) for convenience, and this setting allows me to control the volume on the receiver using my iPhone's volume buttons. The ARC exception prevents certain settings. The main problem I have is the size. To make the body narrower, it was lengthened. This means I can't fit it into my 2 seater weatherproof box and have to buy a new one. Although my last block fit well, I had to slide the power supply in to avoid losing it, which wasn't ideal either. I'll be upgrading my waterproof connection and using this extension, but it's worth noting that the previous extension I had costs a few times less than this one requires and is smaller. I recommend it with reservations. If your installation doesn't use any of the advanced features of this device, you may be better off purchasing a device that does just what you need and no more. especially if you are on a budget. If you drive long distances on the highest settings you might be better off buying Cat6a or better and on lower settings Cat6 really is the bare minimum.
