## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent reception on all units
*by T***R on September 28, 2018*

I purchased 6 of these units along with 1 transmitter unit. Long story short, all TVs output excellent quality video without any lag. If you like to know the details, read below.The units are shipped by default for unicast mode. If you are using this for unicast, there are other J-Tech Digital products that are much cheaper and will meet your needs. If you want to use multicast, this is the unit for you. The instructions that come with the unit assume that you know what you are doing. The way I have it setup is 1 transmitter to 4 TVs and 2 projectors for a total of 6 units. The CAT 6 out from the receiver goes to a network switch and the receiver gets the Cat6 cable and converts back to HDMI out. Without doing anything, once your connections are complete, you'll get a screen that says "Transmitter found, connecting". It'll never connect until you configure the unit to multicast. To do this, you have to connect a laptop or computer to the same network switch and type in the address that you see on the screen of the TV which will open the web GUI. Here, you can change it to multicast mode and reboot. Once the reboot is complete, you'll have the picture displayed. of what ever you have connected.Hope this helps

### ⭐⭐⭐⭐⭐ 4K With 1x3 Setup (TVs In Portrait Orienation)
*by T***A on April 2, 2020*

I bought these about a year ago straight from the J-Tech Digital website (not Amazon) because I was not sure at the time if their "lifetime support" was covered for Amazon purchases. Like now, the prices appear to be exactly the same and shipping was also free from the J-Tech Digital website.I purchased x1 transmitter (JTECH-VW-4KPT) and x3 receivers (JTECH-VW-4KPR) for a 1x3 setup with TVs in portrait orientation. My media player is an Odroid-N2 (running Coreelec aka Kodi). My connections are as follows [Odroid-N2 (HDMI Source) --> Anthem Receiver --> JTECH-VW-4KPT --> Netgear Switch --> JTECH-VW-4KPR --> TVs]. I'm not 100% sure how it works, but each TV says it is showing 4K (so ~12K total). The total image is definitely at least 4K. But I am not sure how the source could start at 4K and then expand to 12K. Either way, it looks great!Things I learned along the road to setting this up.1) J-Tech customer service has been excellent.2) You will need to turn on multi-casting for the transmitter and receivers.3) You will either want a switch that will allow multi-casting to only the specific ports the transmitter and receiver are plugged into. Multi-cast packets are basically a way for the transmitter to flood the video packets to all receivers. This allow all TVs to display their portion of the image at the same time. You do not want this multi-cast traffic flooding your whole network.3b) Another solution for this is to isolate these on their own 1gb basic switch which is not connected to your regular network. Then these multicast packets are not able to flood your regular network.4) Try to keep the length of ethernet cable going to the receivers the same length. You want the video to be in sync for all of your TVs.5) My units all came setup to assign themselves a random 169.254.x.x IP address. J-Tech has a tool on their website to help you find each device and set them to DHCP (automatically get an IP address from the router) or allow you to assign them a Static IP. If you opted to put these on their own separate switch (3b) then you do not need to worry about this.6) On the Video Wall tab of each device, be careful which device is selected when hitting apply.7) On the transmitter: Turn On "Enable Video Over IP", "Enable Video Wall", "Best Effort", "Maximum Frame Rate Effort 100%", "Enable USB Over IP in Auto Select mode"8) On the receiver: Turn On "Enable Video Over IP", "Enable Video Wall", "Scalar Output Mode Pass-Thru", "Enable USB Over IP in Auto Select mode"9) You do not need a POE switch. But it makes powering these so much easier.10) Don't forget bezel gap compensation. I got really into it an purchased a caliper to get as accurate a gap distance as I could. Overkill, yes. But also worth it.Overall if I build another TV, these are likely the controllers I would use.Edit:These units send the IR signal from your remote, through the transmitter, to each receiver, and finally to each TV. With some clever placement I am able to turn all three TVs on/off with one button press.
