HDMI over Ethernet was a bit of a learning curve. Priror to choosing Gofanco, I used another vendor's product with disappointing results, mostly image dropouts at inopportune moments, which turned out to be poor hardware, not my wiring job. Since I made the switch to Gofanco, I am very happy. Gofanco's directions and recommendations are spot-on. Their equipment worked perfect on the same CAT6A wiring.Their cabling best recommendation is premade Cat6/6A/7 solid copper (not stranded copper) directly between the Receiver & Transmitter, no patch panels, couplers, or keystones in the middle. What I ended up doing was somewhat close- I had a patch panel and aesthetics to be concerned about. Therefore, I ran solid copper Cat6A from end to end, however I terminated the ends of the main cable with keystones at the wall and patch panel. I then used standard solid copper Cat6 (not 6A) cables from the wall/patch panel to the transmitter/receiver.Some notes on Ethernet cabling. Shielding. It's highly unlikely to help in all but the noisiest of environments. The electromechanical characteristics of unshielded cables actually help products like this HDMI transmitter work properly. Save your money and go for a higher quality unshielded cable instead. What is higher quality? Solid copper core. Stranded copper cables (while within spec) are fine for traditional data and gigabit speeds. However, at higher frequencies and 10gig rates, stranded's ability to work at that rate over long distances falls off more quickly than with solid copper. In terms of this HDMI extender, remember it isn't ethernet-protocol based at all, it's just using the cable. Get a solid copper core cable, and you will have a better experience. Finally, I'm calling out CAT7. This is not a standard IEEE certified standard. CAT7 performance is within reach of CAT6A. Also, vendors tend to "lie" about CAT7's superiority while selling you a rebranded CAT6A cable. In the IT Industry, CAT7 has a bad rep for being nonstandard (read: proprietary). The leap was made from CAT6 -> CAT8, which was IEEE certified. This is very much a case of "just because it's a bigger number, doesn't make it better."In short- with your cabling:* Prefer solid copper core over stranded* Use unshielded cables* Cat6A is the sweet spot, but CAT6 works great as well* If you can buy a premade 6A unshielded solid copper core cable, that's the best optionMy use case is ultimately with a PC with quad monitor output. Two outputs are used with 2 real monitors, 1 output for 2 real 4k TVs. The third (4K TV) output is a mirror of monitor 1. The 4k TVs are located in the office and living room, therefore they can display the same image from the same source, in two different rooms. I used the Gofanco's HDMI Loop Out to mirror the 1st transmitter's output into the 2nd transmitter. This has worked great and it overcame Windows' limitations of how many screens can mirror one source as well as not requiring additional HDMI splitting hardware.My source signal is 1080p/60 since that's the limit of my monitors in the office. Just to test, I've driven a 4k to the TVs by themselves. While it worked fine - no dropouts or glitches - the GPU has trouble with game performance at 4k. Until I get a more powerful GPU, 1080p is fine and is a consistently good performance level for what I play.I could not be any happier with these. If I had a complaint is that these devices run hot, so operate them in well-ventilated areas to keep them cool. The first of my two, I have had in place for a year and a half as of this writing, and it works just as well now as day one.

We've got two sets of these daisy-chained together in the server room by running the HDMI out from a computer to the HDMI in on one Tx (Tx #1), then from Tx #1 HDMI out to HDMI in on another Tx (Tx #2). They've been running 24hrs a day flawlessly sending digital signage output from a computer in a building's server room to two different displays. The distance is almost the max at about 130' and there are no issues with color, resolution, or anything else. Again, they've been working flawlessly running 24/7.

Installing Home Audio Dealer.Purchased 3 of these to distribute audio to a remote head-end. 25 feet max from each display unit. Cat 6 cable.First one was bad out of the box. No picture or loop out.Second one worked for audio to Yamaha receiver.Loop out worked for display - LG 6190 75".No remote control capability from txr to rcv unit. Couldn't adjust or mute audio.Technical support was basically non-existent.Leave a VM and hope they get back to you.Called at 1PM EST. Call returned at 6 PM after we had departed from client's home.Tech had no clue what was going on. Told that they would get a unit connect it on the bench and get back to us.Never received a call.This product had great specs. We would have used this in a number of upcoming projects, if it had just worked.Definitely not worth the headaches and time.

using cat 5 i was able to use this to connect to my BENQ T800k and HTPC to Enclave Cineaudio.no issues . used flat white cat 6, hid it under the baseboard. great streaming 4k , playing 4k mkv from HTPC

Full 4K video works great across a 100ft Cat 5e cable.
