Review: Long distance 4K/60 Hz HDR signal is no problem with the 4KEX70-H2 - This review is for the AV Access 4KEX70-H2, HDMI 2.0 Over HDBaseT Extender. The packaging was excellent, with everything packed well to protect against any kind of shipping damage. The H2 comes with a transmitter, a receiver, a single 18VDC power supply, an IR transmitter, and IR receiver, two Phoenix male connectors for RS232 passthrough, and a user manual. Setup is very easy. Connect the transmitter and receiver with a suitable Ethernet cable, connect your HDMI source to the transmitter, connect your TV via HDMI to the receiver, connect the power supply to either the transmitter or receiver (Power over Ethernet is bi-directional so it doesn’t matter which unit has it), and then plug in the power supply. The units power up quickly, with both showing a steady power light almost immediately. There will be a slight delay as the transmitter and receiver negotiate the connection, but in all of my uses that is only a few seconds. Once the connection is stable the power and link LED lights will be on steady, the status LED will blink, and the HDCP LED will either be on or off depending on the signal having HDCP or not. I have an Onkyo TX-NR676 4K/60 Hz HDR receiver that has HDCP 2.2, a Shield TV, a PS4, and a Vizio M55-E0 4K/60 Hz HDR TV, and everything works exactly as it should. I use a 26ft CAT-7 cable run in-wall, with CAT-6 keystone passthrough jacks on each end, and CAT-7 patch cables that connect to each of the H2 units. I went with CAT-7 just to allow for future expansion, but I tested the setup with a standard 20ft CAT-5e cable and I had no issues at all, which supports the manufacturer recommendations for cable type and length. I’ve had no connection issues, no intermittent signal issues, and no signal quality issues. The receiver does get very warm to the touch, but since this is passively cooled and it uses the metal case to aid in cooling, I’m not concerned with it. As long as there is adequate ventilation I don’t expect any problems at all. I’ve had these powered up for over 8 hours and haven’t had a single issue due to the heat. I do have a UPS configured with my receiver as a master, so the H2 units are powered off when the receiver is turned off/goes into standby, so I don’t have any experience with heat when the devices aren’t being used – although I did read other reviews that stated the receiver is still warm even if there is no input signal being transmitted. Overall, I’m very happy with the 4KEX70-H2 in my home theater setup and I recommend using them if you have a long (25ft+) distance between your TV and your input devices.
Review: Actually works! - i tested 5 different brands/models of 4k hdmi extenders before these and all had their issues except this one. My use case is video from Nvidia Shield TV to Denon Receiver into HDMI Extender over can6a about 30 feet to an Epson projector. Picture shows up even past the splash screen (most of the other models didn't make it past the splash screen) and in 4k (that was another brands issue) and CEC works for the most part. The off command on the Nvidia Shield turns off the projector, unfortunately waking the Shield TV with the Shield Remote does not consistently wake the projector. Sometimes it doesn't work, sometimes it does (though it often takes up to a minute), but to be fair i really can't place the blame on the extender, it could be any of the devices in the chain (I actually suspect the projector) and it worked as well or better than any other unit i tested. A quick note of advice. After doing some rack work (I shortened the cat6a cable going out of the unit) when I plugged the Extender in, the power button flashed red and no other lights lit up and there was no picture on the screen. It turns out I wired the cat6a cable exactly backwards and obviously it didn't work. Just a word of advice if you have no picture and a flashing red power light: check your cable termination.

### ⭐⭐⭐⭐⭐ Simple to set up, works awesome.
*by G***N on April 27, 2018*

I decided to move all of my gear (network, AppleTV, Xbox, audio amp, etc) to a closet rather than have all of it and the mess of wires under the TV. Since it's unrealistic to make custom length HDMI cables at home, I found this "BALUN" device that can carry HDMI over a standard ethernet cable. AV Access HDMI 2.0 has been the easiest to get wired and running. Simple beyond expectations. You only need to power one end. The other is automatically powered over the ethernet cable. The's no additional latency as far as I can tell, so gaming consoles work fine. I've had video conversion hardware in the past where the latency (the time between your controller input and the result appearing on the TV) was a huge problem and made gaming impossible (think dodging an opponent and your character doesn't actually dodge until a half second or more later), so I was a bit concerned. No problems like that whatsoever with this box. There was a minor issue with one of the IR cables. I sent them a note through Amazon. AV Access customer service replied the same day, and within a couple of days after that I had a replacement set of cables at no cost and more importantly -- no hassle.
