OREI KVM 4K HDMI Over Ethernet Extender Balun Over CAT7 230ft, POC HDCP 2.2

This KVM over ethernet extender really works great. I used a 100 ft Cat7 cble to connect a 4K portable monitor. using mirrior mode at 4K with LINUX has no problem at all.1) 4K video. This works great, although 3840X2400 doesn't work with my 3840X2400 monitor, 3840X2160 does work, xrandr says 3840x2160@30, but I don't see any flickering.2) there is almost no latency at all using both mouse or touchpad, no delay with my portable keyboard. This is really a premium feature to me as I type really fast,I feel like this is really a solid product. for under 100$, I really recommand this extender.

Purchased thinking my existing "4K" HDMI cables were sufficient. Paired with new Cat6 run around a new construction home, looking to keep all my computers and noisy equipment away from my TV upstairs. Lag and color inaccuracy were an issue until I grabbed a pair of HDMI 2.1 "8K" cables for $10 for a 2 pack here. All issues vanished, and you could almost game on this connection now, almost zero latency and beautiful picture. It's ideal for home theater and that's what I use it for. Now I get to kill my snooping TV's network access!

I wanted to like this product. It is well built and well packaged. Compared to other’ direct from china’ KVMs this was far superior in build quality, documentation and accessories. HOWEVER, the USB functionality will not work with for touch function on a display. The two on the unit are apparently dedicated for mouse and keyboard. Therefore, this unit could not work and I had to return it.

My goal was to use my computer in two places. It's one part convenience (I can work inside or in the detached office), part insurance (I can keep the expensive hardware in the house, far from rental clients), and part functionality (the tower won't be adding any fan noise to my recording studio audio). I have identical 4K monitors in both locations, with a 100 ft. Cat7 cable between them.At first, I couldn't figure out why the screen was blacking out randomly for a few seconds at a time. I thought maybe the CAT cable wasn't keeping up with video, control, and audio simultaneously, or it was a shielding issue (based on other comments). After troubleshooting everything I could think of, I got new HDMI cables that I knew would be version 2.1. That made the blacking out go away and now it's working flawlessly. So, make sure to try that, if you're having issues. An HDMI is a CAT cable with a different connector; a cheap one might not keep up with 4K/60.There are no drivers to install and the housing and ports all appear solid. Overall, I'm satisfied with the money saved over more expensive options. If you have the money and don't want any hassle, maybe a more expensive one would be better. But, they might all have the same quirks.

Exelente producto

I use this to run the feed from my security cameras from a splitter to my TV.The units seam to have a sturdy case and were very reasonably priced.No issues with setup at all, simply connect the transmitter to your source, connect the receiver to your Tv/monitor, and run a ethernet cable between them. They connect instantly and I haven't had any issues with video quality or them not being compatible with the PCs/monitors and TVs i have used.

I would give this one star but it works most of the time so I give that an extra star for that. The problem is occasionally it will stop entirely and sometimes the video starts blinking; goes off briefly and then comes back on; about once a minute. The solution for me is to reset by unplugging and replugging the power adaptor. I am using it at 1080p resolution. It was a good idea when it worked well enough!

Works very well. My house has CAT6 cabling however using a 4K monitor was a little blurry. It was lag free.

I finally found the perfect way to stream my PC directly to my TV! I set up a server in my other room, but it was a pain to install an HDMI cable from there to my bedroom. Luckily, there was already a LAN cable installed, and this product worked great. I tried some cheap TX-RX transmitters, but none of them worked because my TV is HDCP compliant. There are different models available, some of which are cheaper than this one, but I chose this one because it also has USB passthrough so I can connect my Keyboard/Mouse/Gamepad to it, and also stream 4K at 60 frames per second. My stream is working without any lags, but there’s some flickering on the TV. Maybe it’s because of the HDMI cable and I need to replace it.Otherwise, this product is worth the price and highly recommended!

had some issues with it, it's overall an ok product but found that it cannot properly detect the 3440x1440 resolution but only 1920x1080 or 4k via hardware switches with wrong scaling.alos the wireless keyboard is typing all the characters wrong via kvm..

I bought this KVM thinking it can do over ip but to my dismay it will only worked via one cable that must support Poe as the power supply is at one end distributed to the other. Not too sure what case use for just one cat6 cable as I believe most getting kvm is precisely to make available control and command to the other end of the network. Perhaps it my fault but your description could have been clearer and of yes why no bold model number it will clue people in which one is getting

Very bad product, very low image quality and seller won't refund full amount after you test the item. Don't buy i advice you.

Works like charm. However beware that the product works with CAT 6/7 Cable only as per the specifications. If you happen to have a CAT 5e cable It won't work over few meters. I have been using a CAT 6 Cable for approx 30 Meters and it works. Absolutely no lag. Mouse and Keyboard also work fine.
