ROFAVEZCO HDMI Extender Over Ethernet 4k 60HZ Uncompressed 18G/BPS Over Single Cat5/6 up to 40m(165ft), RS232+POE+IR+HDCP2.2, HDR CEC EDID Management.

I was looking for a product to replace a previous solution from StarTech which did perform well for video, but required 2x Cat5E to deliver 'acceptable' video to my office from a PC in the garage. This unit does better and with only one Cat5e cable.When comparing the similar devices before buying this, I was a little worried that this would not be a high quality unit, given the price, and if it failed then I could always buy another one, or go for something else.Boy was I ever wrong. This thing is amazing!I specifically wanted a product that would deliver 4:4:4 chroma-subsampling, basically so that there are no video compression artifacts ( fuzziness, or colour bleeding ) in the video at my desk. I also wanted support for 4k60. What I get is perfectly crystal clear HDR content and gaming.I was really impressed with this pair of units, they actually quite happily run are 4k75 on my current hardware over approximately 40m of Cat5E, though your mileage may vary. I'm using a screen resolution of 2560x1080, so not quite 4k, which probably means the resolution headroom is allowing the slightly higher refresh rate.The computer I use as a video source is a dual-boot linux and windows machine and I have never had any issues with switching between environments. It just keeps working.I've never used the IR or RS232 features, but I will say that the receiver unit is small and light enough that I have it fixed to the wall under my desk with 2 command strips and it has not fallen off yet.The power delivery over Cat5 is a bonus as it means I don't have an extra power supply or cable to cable-manage under my desk. There is a socket on the receiver device, i guess this is in case its ever needed, but I've never needed to give it any extra power. On the topic of power, the power supply that comes in the box has a little nut on the plug so it can be fixed into the transmitter so that it does not fall out, which has been really handy in the initial few days while getting it all fixed to the wall in the garage.The one thing I did notice when I first plugged all this in is that the transmitter gets very warm, almost warmer than I would want it to get, but it's not been a problem and performance has been rock solid for almost a year now.I use this in a setup with a ezcoo kvm switch so that I can flip the monitor and keyboard on my desk between the PC in the garage and a laptop on the side of my desk, it's a good setup and works very well. I'm very happy with it and would recommend ezcoo products. They are excellent value for money and perform at least as well as one would expect, probably better.

I purchased one set of these to use with a 4K projector and was so impressed, I purchased another to use with a 4K TV.Both sets work over cat5e Ethernet. One total cable length is about 12m, the other is much longer at about 24m. In both instances the Ethernet cables go back to a patch panel from my AV rack and I then used Cat 5e patch leads to link them together. In other words, these are not just single lengths of cable. It also means you can use them with RJ45 sockets.Initially when I connected up one set (transmitter and receiver) it would not work which led to the discovery that there was a loose twisted pair at one of the RJ45 sockets. The problem disappeared once I fixed this. Incidentally, I found the LEDs particularly helpful to confirm whether signals were actually being sent / received between the units but they can be a bit distracting in a darkened room (they cannot be turned off).Although the units look identical, one is marked ‘transmitter’ and the other ‘receiver’ in very small writing, so don’t make my mistake of connecting them up the wrong way round.As other reviewers have stated, both units run surprisingly hot.The IR emitter and receivers also work well, albeit they are not marked up so you have to guess which one transmits (it’s the bigger one) and which one receives (the smaller teardrop-shaped one).It’s a pity there is no audio return channel (ARC). It seems that Ezcoo does make a more expensive unit that includes this function but it only appears to be on sale in the USA. Also, if you mount the unit using the supplied self-adhesive Velcro pads or the supplied brackets and screws, it’s impossible to disconnect the Ethernet cables without dismounting the units because the spring clips used to secure the cables aren’t accessible. Ezcoo could easily fix this if they manufactured the units so the Ethernet ports were flipped 180 degrees. Also the self adhesive pads used to secure the IR transmitters are not strong enough and mine soon fell off.Another thing I would like to have seen is the ability to connect a 12v trigger in order to turn on the units remotely rather than being left ‘on’ all the time. I suppose I could fix this with a smart plug but that’s yet another command I’d need to explain to the family in what is already a complex setup!
